Embodiment 1

[0070] An embodiment of the present invention is a security authentication method for Internet of Vehicles communication based on a national secret algorithm. Based on the SM2 digital signature algorithm, the SM2 public key encryption algorithm and the SM3 hash algorithm, the on-board terminals and roadside facilities in the Internet of Vehicles realize the Two-way identity authentication between terminals and roadside facilities, such as figure 1 shown.

[0071] The on-board terminal and the roadside facility are factory-preset with a random number generator in the security chip to generate the private key respectively , , and stored in the storage unit of the security chip, which cannot be acquired by external devices.

[0072] Before the two-way security identity authentication between the vehicle terminal and the roadside facility, the vehicle terminal and the roadside facility respectively send the certificate request file to the CA, and the CA respectively issues th...

Embodiment 2

[0108] Another embodiment of the present invention is a vehicle networking vehicle terminal based on a national secret algorithm, including a random number generation module, a certificate issuance module, an identity authentication message construction module, and an authentication module, such as Figure 5 shown. The vehicle-mounted terminal in this embodiment implements the security authentication method for the vehicle-to-vehicle communication vehicle terminal based on the national secret algorithm described in Embodiment 1, wherein,

[0109] The random number generation module generates a private key through the random number generator in the security chip preset in the vehicle terminal, and stores the private key in the storage unit of the security chip, which cannot be acquired by external equipment;

[0110] The certificate issuing module is used for the vehicle terminal to send the certificate request file to the CA, and to receive the digital certificate generated by...

Embodiment 3

[0114] Another embodiment of the present invention is a vehicle networking roadside facility based on a national secret algorithm, including a random number generation module, a certificate issuance module, an identity authentication message construction module, and an authentication module, such as Figure 5 shown. The roadside facility of this embodiment implements the security authentication method for the roadside facility of the Internet of Vehicles communication based on the national secret algorithm described in Embodiment 1, wherein,

[0115] The random number generation module generates a private key through the random number generator in the security chip preset in the roadside facility, and stores the private key in the storage unit of the security chip, which cannot be acquired by external equipment;

[0116] The certificate issuance module is used for the roadside facility to send the certificate request file to the CA, and to receive the digital certificate gener...

Abstract

The invention belongs to the technical field of vehicle network security, and discloses a vehicle network communication security authentication method, system and equipment based on a national secret algorithm. The method of the present invention includes: the vehicle-mounted terminal constructs an identity authentication request message and sends it to the roadside facility; the vehicle-mounted terminal receives the identity authentication response message and verifies the signature; if the verification is successful, the vehicle-mounted terminal calculates the session key and its hash value and constructs a confirmation message to send To the roadside facility; it is used by the roadside facility to calculate the session key and its hash value for comparison and verification; if the hash values ​​are equal, the security authentication succeeds and a session key is generated; if they are not equal, the security authentication fails. The present invention combines SM2 digital signature algorithm, SM2 public key encryption algorithm and SM3 hash algorithm to ensure that the method can be applied to the communication process between vehicle-mounted terminals and roadside facilities, and can resist Various attacks.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles security, and in particular relates to a security authentication method, system and device for Internet of Vehicles communication based on a national secret algorithm. Background technique [0002] Driven by the existing computer and communication technology, the traditional automobile industry realizes the communication between vehicles and between vehicles and roadside facilities by carrying sensor equipment and communication equipment. However, due to the openness and high-speed mobility of the Internet of Vehicles communication environment, the vehicle's user identity, geographic location and other private information may be exposed in the network. If the user's identity is not legally authenticated, the user's information cannot be effectively protected, and the Internet of Vehicles communication will bring a series of security problems such as user privacy leakage, identity frau...
