Embodiment 1

[0048] The embodiment of the present invention provides a two-way authentication method between a vehicle-mounted terminal and a central platform, and the main contents of the method include:

[0049] The key management system uniformly distributes the corresponding unique key information in advance for the vehicle terminal and the central platform, where the key information consists of the terminal / platform ID (identification number), key ID, time stamp and terminal / platform public key. The key information signature private key is signed, and the key information signature public key is issued to the vehicle terminal and the central platform as the basis for mutual authentication.

[0050] The vehicle-mounted terminal and the central platform perform mutual authentication through the signature public key of the key information, and judge whether the key information is legal according to the terminal / platform ID, key ID and time stamp in the content of the key information.

Abstract

The invention relates to a bidirectional authentication method and system for a vehicle-mounted terminal and a central platform, and the method comprises the steps: distributing corresponding unique secret key information to the vehicle-mounted terminal and the central platform, signing a signature value signed by a private key through the secret key information, and issuing a secret key information signature public key to the vehicle-mounted terminal and the central platform for mutual authentication; the vehicle-mounted terminal and the central platform perform mutual authentication througha secret key information signature public key, and judge whether the secret key information is legal or not according to a terminal / platform ID, a secret key ID and a timestamp in the secret key information; according to a temporary public key and a random number generated by the vehicle-mounted terminal and the central platform in the interaction process of the vehicle-mounted terminal and the central platform, a session key is negotiated by combining a public / private key of the vehicle-mounted terminal and the central platform, and encryption communication is performed through the negotiatedsession key. According to the invention, the coupling problem of the central platform and the key management system is improved, the terminal key leakage risk is reduced, and the two-party authentication efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of network authentication, in particular to a two-way authentication method and system for a vehicle-mounted terminal and a central platform. Background technique [0002] With the rise of Internet of Vehicles technology, more and more vehicles are equipped with vehicle-mounted terminals with wireless communication functions. However, the vast majority of vehicle-mounted terminals do not take security measures, and directly transmit communications in clear text on the Internet. With the rapid development of the Internet today, security issues are becoming more and more prominent. Clear text communication may lead to theft of communication data, leakage of sensitive information, and even criminals issuing control commands to vehicle terminals through protocols, resulting in more serious security risks. [0003] In current security technologies, a digital certificate SSL (Secure Sockets Layer, Secure Sockets ...
