Battery Data Management System And Operation Method Thereof

Abstract: An operation method of a battery data management system, according to an embodiment disclosed in the present document, may comprise the steps of: a terminal acquiring a public key and a first message by transmitting battery-associated information to an authentication server, encrypting the first message via the public key, and transmitting the encrypted first message to a battery authentication module; the battery authentication module acquiring the first message by decoding the encrypted first message by using a pre-stored first key, generating a second message that is based on random number information, encrypting the second message via the first key, and transmitting the encrypted second message to the terminal; the terminal acquiring the second message by decoding the second message via the public key, and transmitting the first message and the second message to the authentication server; the authentication server generating a third message that is based on the random number information, and transmitting the generated third message to the terminal; the terminal encrypting the third message via the public key, and transmitting the encrypted third message to the battery authentication module; and the battery authentication module acquiring the third message by decoding the encrypted third message by using the first key, generating a second key that is a shared session key, encrypting the second key via the first key, and transmitting the encrypted second key to the terminal.
