An Efficient Pseudonym Management and Data Integrity Protection Protocol

Abstract

The invention discloses a high-efficiency pseudonym management and data integrity protection protocol, which includes three entities: trusted institutions, vehicles and roadside infrastructures. The trusted institutions generate key materials and transmit corresponding key materials to vehicles and roadside infrastructures respectively. roadside infrastructure. After the vehicle obtains the key and public parameters distributed by the trusted organization, it needs to use the signature algorithm to generate a signature for the message to be sent and send it to the roadside infrastructure. After the roadside infrastructure receives the message, it needs to use the signature algorithm to verify the message. Finally, the trusted organization can track the vehicle by monitoring the pseudonym transmission path, and finally obtain the real identity and location information of the vehicle. The invention can not only ensure high-efficiency carpooling and save the transportation cost of the owner, but also improve the loading rate of the driver.

Description

Technical field [0001] The present invention belongs to the field of Internet security technology, and in particular, there is a way to apply to VaNet using a rulbon filter, k-anonymous and hash chain technology to achieve efficient and false name management and data integrity protection protocols. Background technique [0002] In intelligent transportation systems, the use of Vanet, Vehicular Ad Hoc Networks technology in vehicle emergency warning, traffic congestion management, etc. is a typical network of Internet of Things. In order to ensure communication security between vehicles and road-side units, RSUs provide location privacy and integrity protection, simplify deployment public key infrastructure (PKI) and symmetric key infrastructure, suitable for Vanet Safety solutions typically use identity-based encryption techniques for key management. [0003] Regardless of how technology is implemented, a typical identity-based integrity protection protocol includes three parts: ...

AI Technical Summary

Problems solved by technology

Current identity-based data integrity protocol schemes can satisfy requirements (1) and (2), while (3) is largely ignored

Furthermore, while working on the current topic, we found that none of the existing cryptographic primitives can be directly used to achieve the goals discussed above
