CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202421079816 filed on 21/10/2024, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
Generally, the present disclosure relates to VIC provisioning. Particularly, the present disclosure relates to a system and method for provisioning a Vehicle Interface Controller (VIC) of a connected vehicle.
BACKGROUND
Modern vehicles integrate advanced electronic control units, sensors, and communication interfaces to monitor performance, energy consumption, and operational status. The connected nature of the vehicles requires provisioning processes that authenticate vehicle identities, control units, and subscriber profiles to establish secure communication links with telecommunication networks and cloud platforms. Provisioning in the vehicle enables dynamic generation of authentication keys, session management, and profile activation, ensuring vehicles maintain trusted connections to mapping services, remote diagnostics, and location-based applications essential for efficient operation and service delivery.
Conventional technologies in vehicle communication focus on telematics control units, over-the-air updates, and embedded SIM management, which allow vehicles to connect to networks for navigation, diagnostics, and infotainment services. Several provisioning frameworks implement authentication mechanisms based on static keys or pre-registered certificates for secure data exchange. The existing technology relates to embedded SIM (eSIM) provisioning systems that authenticate network access using predefined identifiers such as IMSI and static certificates. The eSIM provisioning systems provide remote subscription management and allow initial activation of communication interfaces. Specifically, during network access, the device initially uses a predefined IMSI stored on the eSIM to identify itself to the carrier’s network. The network queries the IMSI and establishes that the device is allowed to access the provisioning services (such as the Subscription Manager Servers), restricting access to essential provisioning in case of requirement.
However, there are certain problems associated with the existing or above-mentioned mechanism for provisioning a communication interface controller in a connected vehicle. The existing technologies reliance on static authentication procedures exposes communication interfaces to spoofing, replay attacks, and unauthorized access. Further, conventional eSIM provisioning lacks adaptive mechanisms to integrate dynamic contextual parameters, such as, but not limited to, geolocation, timestamp, and diagnostic data for enhanced security. Furthermore, the existing technologies limit real-time validation of vehicle and controller identities. The embedded SIM provisioning techniques authenticate based on fixed identifiers without accounting for operational context or session-specific attributes, reducing resilience against tampering. Additionally, validation processes occur at network endpoints without verifying the integrity of identifiers against vehicle-generated parameters, leading to potential security breaches.
Therefore, there exists a need for a secure, interoperable, and automated alternative for provisioning a communication interface controller in a connected vehicle.
SUMMARY
An object of the present disclosure is to provide a system for provisioning a communication interface controller in a connected vehicle.
Another object of the present disclosure is to provide a method for provisioning a communication interface controller in a connected vehicle.
Yet another object of the present disclosure is to provide a system and a method for the dynamic generation of the authentication keys for provisioning.
In accordance with a first aspect of the present disclosure, there is provided a system for provisioning a communication interface controller in a connected vehicle, the system comprising:

The system for provisioning a communication interface controller in a connected vehicle, as described in the present disclosure, is advantageous in terms of ensuring dynamic generation of the authentication keys based on the contextual parameters, providing high resistance against replay attacks and credential spoofing in the provisioning server. Further, the association of identifiers with the cryptographic signatures guarantees data integrity and prevents manipulation of the vehicle identifier, controller identifier, and subscriber identity during transmission. Furthermore, the subscriber profile management server enforces strict validation of cryptographic signatures, ensuring that only verified identifiers result in subscriber profile activation. Moreover, the linkage of subscriber profile activation with the cloud platform services enables authenticated access to navigation, telemetry, and diagnostics, strengthening the reliability of connected vehicle operations.

Subsequently, the advantages include, but are not limited to, strengthened security of the communication interface controller 102, reduced latency in profile provisioning, improved integrity of vehicle-to-cloud communication, and enhanced trustworthiness of connected vehicle 104 operations through the authenticated subscriber profile activation.
In an embodiment, the provisioning server 110 is configured to generate at least one authentication key dynamically based on at least one contextual parameter. Specifically, the communication interface module 106 collects at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity from at least one vehicle subsystem 108 and transmits the information to the provisioning server 110. The provisioning server 110 processes the received identifiers and initiates computation of the authentication key in real time, ensuring that each communication session associated with the communication interface controller 102 is uniquely bound to the contextual information. Further, the dynamically generated authentication key secures the transmission path and forms the basis of subsequent verification steps undertaken by the subscriber profile management server 112. The process involves the provisioning server 110 utilizing the contextual data, such as, but not limited to, session timestamps, vehicle identifiers, or diagnostic session parameters, to calculate the authentication key through cryptographic functions. Furthermore, the authentication key directly links to the communication session initiated between the communication interface module 106 and the provisioning server 110, eliminating the possibility of reusing static credentials across multiple sessions. The authentication key is securely mapped to the at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity before being applied in the authentication process. Moreover, once generated, the authentication key governs the secure validation of the transmitted identifiers, and only identifiers bound to the valid authentication key are allowed to progress to the subscriber profile management server 112 for integrity verification. Consequently, the creation of a non-replicable and context-specific authentication environment is achieved that enhances the security of subscriber profile provisioning for the communication interface controller 102. The dynamic nature of the authentication key ensures that every provisioning attempt reflects real-time system conditions, thereby eliminating vulnerabilities associated with predictable or static authentication mechanisms. Additionally, the advantages include, but are not limited to, robust session-specific validation of the vehicle identifiers, controller identifiers, and subscriber identities, improved protection against replay attacks and credential theft, and strengthened trust in subscriber profile activation workflows.
In an embodiment, the authentication key is generated dynamically based on a combination of the contextual parameters, wherein the contextual parameters comprise Vehicle Identification Number (VIN), current session timestamp, geolocation coordinates, and diagnostic session parameters. Specifically, the communication interface module 106 acquires the at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity from the at least one vehicle subsystem 108 and transmits the information securely to the provisioning server 110. The provisioning server 110 computes the authentication key by combining multiple contextual parameters, including but not limited to the Vehicle Identification Number (VIN), the current session timestamp, the geolocation coordinates of the connected vehicle 104, and the diagnostic session parameters associated with the communication interface controller 102. Further, the integration of the contextual parameters ensures that the authentication key remains unique for each communication session and is tightly bound to the operational state of the connected vehicle 104. The process involves the provisioning server 110 performing the cryptographic computation process that incorporates the VIN as a static but unique element for each connected vehicle 104, the current session timestamp as a temporal marker, geolocation coordinates as a positional attribute, and the diagnostic session parameters as operational indicators. Furthermore, the provisioning server 110 applies a hashing algorithm or an asymmetric cryptographic function over the combined contextual parameters to produce the authentication key. The authentication key is further associated with the at least one vehicle identifier, the at least one controller identifier, and the at least one subscriber identity to enforce strict authentication boundaries. Consequently, the heightened security and contextual relevance of the authentication process are achieved for provisioning the communication interface controller 102. By incorporating the VIN, the session timestamp, the geolocation coordinates, and the diagnostic session parameters, the authentication key reflects both the identity and the dynamic operational environment of the connected vehicle 104. Additionally, the advantages include, but are not limited to, prevention of replay attacks by binding authentication to a unique timestamp, elimination of spoofing attempts by linking authentication to the vehicle-specific VIN, mitigation of unauthorized access by validating against precise geolocation coordinates, and enhancement of the system reliability by incorporating the diagnostic parameters that confirm the controller’s active state.
In an embodiment, the provisioning server 110 is configured to time-limit the authentication key for each communication session and discard the communication session after completion of the time limit. Specifically, the communication interface module 106 receives the at least one vehicle identifier, the at least one controller identifier, and the at least one subscriber identity from the at least one vehicle subsystem 108 and transmits the information to the provisioning server 110. The provisioning server 110 generates the authentication key dynamically, associates the authentication key with the transmitted identifiers, and enforces a strict validity period. The procedure involves the provisioning server 110 maintaining the temporal validation process that links the authentication key to a specific session lifespan. Furthermore, the authentication key is computed using contextual parameters and stored temporarily within a secure session registry of the provisioning server 110. Each communication session involving the communication interface controller 102 is continuously monitored against the active time limit. Moreover, at the expiration of the defined time limit, the provisioning server 110 automatically discards the authentication key and closes the corresponding session channel, ensuring that no further identifier validation or subscriber profile activation attempts occur over an expired key. Any subsequent authentication request requires regeneration of a new authentication key based on updated contextual parameters, maintaining exclusivity for each session lifecycle. By enforcing time-limiting, the provisioning server 110 ensures that each communication session remains isolated, temporary, and uniquely bound to a single lifecycle, thereby preventing misuse of previously validated identifiers. Additionally, the advantages include, but are not limited to, enhanced resistance to replay attacks, minimization of risks associated with credential leakage, reduction in unauthorized reuse of session data, and improvement in overall trustworthiness of subscriber profile activation processes performed by the subscriber profile management server 112.
In an embodiment, the provisioning server 110 is configured to authenticate the at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity based on the generated at least one authentication key. Specifically, the communication interface module 106 transmits the collected identifiers from the at least one vehicle subsystem 108 to the provisioning server 110. The provisioning server 110 generates the authentication key dynamically through the contextual parameters and cryptographic computation and directly binds the generated authentication key with the identifiers. Further, the authentication process verifies that the transmitted identifiers align with the parameters used for generating the authentication key, ensuring consistency and security before transferring the authenticated information to the subscriber profile management server 112. The process involves the provisioning server 110 applying a verification algorithm where the authentication key functions as a reference signature for the received identifiers. Furthermore, the provisioning server 110 validates the at least one vehicle identifier against the authentication key by matching the embedded VIN data, validates the at least one controller identifier by confirming cryptographic association, and validates the at least one subscriber identity by checking alignment with the contextual parameters incorporated into the authentication key. Moreover, the authenticated identifiers are further transmitted securely to the subscriber profile management server 112 for integrity verification and subscriber profile activation. Any identifier failing to match the authentication key is discarded, and no further processing occurs for that data set. Consequently, the establishment of a robust verification framework is achieved where the authentication key operates as the binding element between identifiers and contextual session data, ensuring absolute security in the provisioning of the communication interface controller 102. The authentication mechanism prevents injection of false identifiers, enforces strict alignment between identifiers and contextual attributes, and eliminates any possibility of unauthorized profile activation. Additionally, the advantages include, but are not limited to, enhanced accuracy of identifier validation, increased resilience against spoofing attacks, strengthened assurance of the subscriber profile authenticity, and improved trust in connected vehicle 104 communication.
In an embodiment, the provisioning server 110 is configured to associate each of the at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity with at least one cryptographic signature. Specifically, the communication interface module 106 receives the identifiers from at least one vehicle subsystem 108 and forwards them to the provisioning server 110. The provisioning server 110 generates the authentication key based on the contextual parameters and applies the cryptographic functions, such as, but not limited to, hashing or asymmetric encryption, to each identifier. Further, the resulting cryptographic signature forms a tamper-resistant digital representation of the identifiers, ensuring that every vehicle identifier, controller identifier, and subscriber identity carries a unique verifiable imprint before being processed by the subscriber profile management server 112. The procedure involves the provisioning server 110 binding identifiers with the cryptographic signatures through signature generation algorithms. Furthermore, each vehicle identifier is processed with the authentication key to create a signature that represents the VIN and related vehicle data, each controller identifier is encrypted with the authentication key to generate a digital signature confirming the controller’s authenticity, and each subscriber identity is signed with cryptographic algorithms that embed contextual attributes such as, but not limited to, session timestamp or diagnostic data. Moreover, the subscriber profile management server 112 validates the received identifiers by comparing the transmitted cryptographic signatures with the reference data, thereby ensuring absolute data integrity before subscriber profile activation. Consequently, the establishment of an immutable verification mechanism that protects identifiers against tampering, replay, or substitution during provisioning of the communication interface controller 102 is achieved. Additionally, the advantages include, but are not limited to, enhanced protection of sensitive subscriber identity information, assurance of authenticity for the controller-related communication, prevention of data manipulation attacks, and improved system-wide confidence in subscriber profile activation.
In an embodiment, the at least one subscriber profile management server 112 is configured to perform integrity verification of the at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity by validating at least one cryptographic signature with a reference data set stored in at least one subscriber profile management server database. Specifically, the communication interface module 106 receives the identifiers from at least one vehicle subsystem 108 and transmits the identifiers to the provisioning server 110. The provisioning server 110 generates cryptographic signatures for each identifier and forwards the signed identifiers to the subscriber profile management server 112. Further, the subscriber profile management server 112 retrieves the reference data set from the subscriber profile management server database and executes a signature validation process to confirm that the received identifiers are authentic and untampered before progressing to profile activation. Furthermore, the vehicle identifier is validated by matching the generated signature representing the VIN against the database entry, the controller identifier is verified by ensuring that the cryptographic signature aligns with the stored reference pattern, and the subscriber identity is authenticated by checking the cryptographic association against the database record. The validation procedure ensures that only identifiers carrying valid signatures that match the reference data set are accepted for further processing. Moreover, any identifier with a mismatched or corrupted signature is rejected, maintaining a strict boundary for integrity enforcement within the subscriber profile management server 112. Consequently, the establishment of a data integrity verification framework is achieved that guarantees secure and reliable validation of identifiers during provisioning of the communication interface controller 102. By cross-verifying cryptographic signatures with a trusted reference data set, the subscriber profile management server 112 eliminates the possibility of unauthorized or manipulated identifiers being used in subscriber profile activation. Additionally, the advantages include, but are not limited to, preservation of end-to-end trust between vehicle subsystems 108, the provisioning server 110, and the subscriber profile management server 112, enhancement of data security by filtering out forged identifiers, prevention of unauthorized subscriber profile activation, and assurance of compliance with secure communication protocols in the connected vehicle 104.
In an embodiment, the at least one subscriber profile management server 112 is configured to generate a subscriber profile activation signal upon successful validation of the integrity verification of the at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity. Specifically, the communication interface module 106 transmits identifiers from the at least one vehicle subsystem 108 to the provisioning server 110, which associates the cryptographic signatures with each identifier. The subscriber profile management server 112 receives and validates the signed identifiers against the reference data set in the subscriber profile management server database 112, and upon confirming authenticity and integrity, produces the subscriber profile activation signal. Further, the activation signal forms the critical command that initiates secure activation of the subscriber profile within the connected vehicle 104. The procedure involves the subscriber profile management server 112 executing a sequence of operations beginning with validation of the cryptographic signatures attached to the identifiers. Furthermore, once the validation confirms complete alignment between the received signatures and the reference data set, the subscriber profile management server 112 generates the subscriber profile activation signal. The activation signal encapsulates the verified identifiers and binds the identifiers with the secure session marker, ensuring that the communication interface controller 102 provisions only authenticated subscriber profiles. Moreover, the generated activation signal is transmitted securely through the system 100 and received by the communication interface controller 102, where the subscriber profile is activated in association with the authenticated vehicle identifier, controller identifier, and subscriber identity. Consequently, the establishment of an end-to-end secure subscriber profile activation mechanism is achieved that ensures activation occurs only after successful verification of data integrity. By generating the subscriber profile activation signal exclusively upon integrity confirmation, the subscriber profile management server 112 prevents unauthorized activations and strengthens the reliability of the connected vehicle 104 communication. Additionally, the advantages include, but are not limited to, guaranteed authenticity of the subscriber profile activation, reduced risk of malicious or fraudulent provisioning, improved synchronization between the provisioning server 110 and the subscriber profile management server 112, and enhanced security in communication flows across the connected vehicle ecosystem.
In an embodiment, the at least one subscriber profile management server 112 is communicably coupled to a cloud platform 114, and wherein the cloud platform is configured to enable at least one of mapping services, location-based services, real-time telemetry, and remote diagnostics upon successful subscriber profile activation. Specifically, the communication interface module 106 collects identifiers from at least one vehicle subsystem 108 and transfers the identifiers to the provisioning server 110, where cryptographic association and authentication are performed. The subscriber profile management server 112 validates the identifiers, generates the subscriber profile activation signal, and transmits the activation signal to the cloud platform 114. Further, the cloud platform 114 receives the activation signal and initiates service enablement functions such as, but not limited to, mapping services, location-based services, real-time telemetry, and remote diagnostics, ensuring that the connected vehicle 104 gains authenticated access to cloud-enabled functionalities. The process involves a structured interaction between the subscriber profile management server 112 and the cloud platform 114. Furthermore, once the subscriber profile activation signal is generated, the subscriber profile management server 112 transmits service enablement metadata embedded within the activation signal to the cloud platform 114. The cloud platform 114 validates the activation signal, associates the identifiers with the authorized subscriber profile, and provisions access to services mapped within the cloud infrastructure. Moreover, the mapping services are activated through integration with the geospatial databases, the location-based services are initiated through GPS-driven data exchange, the real-time telemetry services are enabled by continuous vehicle-to-cloud data streaming, and remote diagnostics are facilitated by routing diagnostic parameters from the communication interface controller 102 to cloud-based diagnostic modules. The subscriber profile ensures that all cloud-enabled services remain bound to authenticated identifiers. Consequently, the seamless extension of subscriber profile activation into the domain of cloud-based services is achieved and which ensures the secure provisioning of the communication interface controller 102, directly enabling trusted digital services for the connected vehicle 104. By binding subscriber profile activation to cloud service initiation, the system 100 eliminates unauthorized access to sensitive mapping, telemetry, and diagnostic resources. Additionally, the advantages include, but are not limited to, real-time delivery of authenticated location services, secured streaming of telemetry data, reliable execution of cloud-based diagnostics, and unified control of vehicle-to-cloud interactions through verified subscriber profiles.
In an exemplary embodiment, the system 100 comprises the communication interface module 106, the provisioning server 110, and the subscriber profile management server 112 operating in coordination with a cloud platform 114. The communication interface module 106 receives identifiers from the vehicle subsystem 108, including, but not limited to, the vehicle identifier with the VIN of “1HGCM82633A004352”, the controller identifier of “CTRL-9087X”, and the subscriber identity in the form of an IMSI value “405872103456789”. Further, the communication interface module 106 transmits the identifiers to the provisioning server 110 for secure processing. The provisioning server 110 dynamically generates an authentication key based on the contextual parameters. For instance, the contextual parameters include, but are not limited to, the VIN, a session timestamp of 1693648200 seconds (Unix time), geolocation coordinates of latitude 28.6139° N and longitude 77.2090° E, and a diagnostic session parameter representing an active diagnostic state “DTC-OK”. The provisioning server 110 computes the authentication key by applying the hash function, such as, but not limited to, SHA-256, across the concatenated contextual string. The concatenated string is expressed as:
S = VIN ? Timestamp ? Latitude ? Longitude ? DiagnosticCode
S = “1HGCM82633A004352?1693648200?28.6139?77.2090?DTC-OK”
The SHA-256 function generates the authentication key Kauth as: Kauth = SHA-256(S)
Kauth=9f2a4b67d2f8b0e1c84df23d6b8b9e39f7a64e25d4b221a9d0c1a82bc86d9
Moreover, the provisioning server 110 associates the authentication key Kauth with the vehicle identifier, controller identifier, and subscriber identity, and subsequently applies cryptographic signing. Each identifier is hashed with Kauth using HMAC-SHA256, resulting in unique cryptographic signatures SigVIN, SigCTRL, and SigIMSI. For instance:
SigVIN = HMAC-SHA256(Kauth, VIN)
SigCTRL = HMAC-SHA256(Kauth, Controller Identifier)
SigIMSI = HMAC-SHA256(Kauth, Subscriber Identity)
Additionally, the subscriber profile management server 112 receives the signed identifiers and validates the identifiers against reference signatures stored in the subscriber profile management server database. For the VIN “1HGCM82633A004352”, the expected signature SigVIN* is computed from the reference dataset, and if SigVIN = SigVIN*, the vehicle identifier is verified. Subsequently, similar validation is applied for SigCTRL and SigIMSI. Upon successful validation, the subscriber profile management server 112 generates the subscriber profile activation signal Psignal = f(SigVIN, SigCTRL, SigIMSI), where “f” denotes a secure aggregation function. Eventually, Psignal is transmitted to the communication interface controller 102, enabling activation of the subscriber profile. Activation of the subscriber profile links the connected vehicle 104 with the cloud platform 114. Further, the cloud platform 114 provisions location-based services by mapping geolocation coordinates of latitude 28.6139° N and longitude 77.2090° E to the navigation grid, real-time telemetry services by streaming speed data of 62 km/h and the battery charge level of 78%, and remote diagnostics by reporting the healthy state with zero active Diagnostic Trouble Codes. The mathematical binding of identifiers with the authentication key ensures that each activation sequence is unique and session-specific, providing strong security against unauthorized access.

- receiving at least one vehicle identifier, at least one controller identifier, and at least one subscriber identity from at least one vehicle subsystem to a communication interface module;
