FIG 23 is a schematic view of the initial stage of the mutual authentication between the distributed components and the general description of the apparatus for 3D printing. As shown, the key generation center or public key infrastructure / Authentication Center (PKI / CA) 2310 generated identity key / device key or digital certificate (public key, private key), and are issued to the server 2320 and 3D printing equipment 2330.
[0132]
About the identity of the key distribution initialization phase, for example, the following key management options are available:
[0133]
Certificate-based (PKI / CA) way;
[0134]
Identity-based public key systems (IBE) manner; and
[0135]
Device pre-shared key (PSK) based manner.
[0136]
The following will the mutual authentication process in the distributed components of the 3D printer embodiment of the present invention is based on three types of key management mode described example.
[0137]
In the certificate-based mode, it is shown in Figure 24, in the initialization phase, issued by the certification authority (CA) 2410 digital certificates to servers 2420 and 2430 3D printing apparatus. Certification process, CA 2410 as a trusted third party, responsible for verifying the validity of the certificate.
[0138]
FIG 25 illustrates an example of processing flow in this mode.
[0139]
① 3D distributed components connected to the printing apparatus 2530 2540, initiates authentication.
[0140]
②3D printing equipment 2540 certificate and signature information be sent to the distributed components 2530.
[0141]
③ distributed components 2530 2540 3D printing apparatus and a certificate signature information is forwarded to the server 2520.
[0142]
④ Server 2540 Certificate 2520 Certificate Server 2520 and 3D printing equipment be sent to the CA 2510 certificate validation, CA 2510 and to verify server 2520 and 2540 3D printing equipment certificate validity.
[0143]
Returned the correct response information ⑤CA 2510 verified.
[0144]
⑥ If the certificate is valid 3D printing apparatus, the server transmits to CA 2510 2520 2530 distributed components for server certificate verification result.
[0145]
⑦ distributed components 2530 CA 2510 returns to the 3D printing apparatus 2540 for server certificate verification result. In order to complete the verification.
[0146]
After authentication by the distributed key agreement member 2530 may be a 3D printing apparatus 2540, and further data communication between the parties is encrypted with a key negotiation.
[0147]
In the embodiment identity-based public key system, shown in Figure 26, in the initialization phase, generates a corresponding key 2610 (PK = ID 2620 and server-based 3D printing apparatus identification ID 2630 by the key generation center (the KGC) , SK). The key to the ID binding. In a public key system, the identity, ID itself may be used as a public key PK, such as identification numbers, email addresses, and so on.
[0148]
Compared with certificate-based authentication, identity public key system is relatively simple, because the identity of the private key is binding and does not require the use of the certificate, which verifies the identity and key relationships through a third party trusted platform.
[0149]
FIG 27 illustrates an example of processing flow in this mode.
[0150]
① identity server 2710 using the public key ID 3D printing 3D encrypted random information, sent over a secure channel 2720 distributed components.
[0151]
② distributed encrypted random member 2720 forwards the information to the printing apparatus 2730.3D 3D printing apparatus 2730 using the private key SK identity 3D decrypted random information.
[0152]

[0155]
Of course, for security communications in the above process flow, you can add the sender's signature for the communication of information to the recipient to confirm the true identity of the actual sender. That is, in addition to sending encrypted random information, but also attach a digital signature for the information. Digital signature is based on their identity private by the sender, obtained by the signature algorithm. Increasing the signature can effectively resist the-middle attack, i.e. inserted between the listener and the distributed components 3D printing apparatus, so that falsified communication content.
[0156]
On the other hand, without the use of random information as a decryption key, the authentication is passed, the distributed key agreement member 2720 may be a 3D printing apparatus 2730, and further data communication between the parties is encrypted with a key negotiation.
[0157]

[0160]
① 3D distributed components connected to the printing apparatus 2930 2940, 2940 issued to challenge information transmitting 3D printing apparatus.
[0161]
The printing apparatus 2940 ②3D ID 3D information and other auxiliary information be sent to the distributed components 2930. Meanwhile, 3D printing, the device 2940 by a preset specific algorithms, according to which the apparatus main key, received challenge information, and auxiliary information send deduced the encryption key EK.
[0162]
③ challenge information distributed components 2930, ID 3D information and other auxiliary information is forwarded to the server 2920.
[0163]
