Anti-quantum calculation distributed Internet of Vehicles method and system based on identity secret sharing and implicit certificates

Abstract

The invention relates to an anti-quantum calculation distributed Internet of Vehicles method and system based on identity secret sharing and an implicit certificate, wherein the client parts and the server parts communicate with each other. The server part comprises a third-party trust mechanism for providing corresponding services and a roadside unit, wherein the client part comprises a vehicle-mounted unit, and is characterized in that each party is configured with a key card, a public key, a private key and algorithm parameters of the own party are stored in all the key cards, and the server part is also configured with a key management server, so that the safety of the identity recognition of the vehicle-mounted unit in the communication process of each party in the Internet of Vehicles is further improved.

Description

technical field [0001] The present application relates to the field of secret sharing, in particular to a quantum computing-resistant distributed vehicle networking method and system based on identity secret sharing and implicit certificates. Background technique [0002] The Internet of Vehicles (IoV) is a wireless local area network technology that uses vehicles, namely on-board units (OBU, on board unit) and roadside units (RSU, road side units) as network nodes, to provide vehicle-to-vehicle (V2V), vehicle-to-roadside unit A mobile network created to provide communication services between (V2R) networks. In the era of rapid development of information technology, the Internet of Vehicles provides technical support for the realization of urban intelligent transportation systems. In the future vehicle network, vehicle nodes can obtain the traffic conditions ahead of the road from other vehicle nodes or roadside units, so as to choose a smoother travel route. It can also p...

AI Technical Summary

Problems solved by technology

[0006] 1. If the OBU ID is made public, it may cause information leakage of the owner

If the ID is recorded in multiple locations, ID tracking can be realized, which is a serious information leakage in some application scenarios

[0007] 2. Issue a symmetric key to the OBU. Since the symmetric key cannot be used for reliable digital signatures, it is not good for identification

[0008] 3. Issue an asymmetric key pair to the OBU and use the private key for digital signature. This method cannot resist quantum computing because the public key needs to be disclosed when verifying the digital signature.

[0009] 4. Issuing the private key of the asymmetric key to the OBU and storing the public key in the server can resist quantum computing, but since the public key at the server is identified by ID or a random number similar to the public key pointer of ID, the ID Or the random number of the public key pointer must be made public, resulting in leakage of user information

[0010] 5. The most important unit of the entire Internet of Vehicles system is TA. If its stored information is stolen, it may cause serious consequences

This solution brings a lot of workload to TA for certificate issuance and subsequent certificate verification, which can easily cause TA's workload to be too heavy
