AI Technical Summary

Technical Problem

In the context of the Internet of Vehicles (IoV), existing access control models suffer from high computational overhead, poor flexibility, and weak functionality. They are unable to achieve fine-grained and multi-layered access control and are vulnerable to malicious attacks that could lead to the leakage and tampering of critical traffic data.

Method used

By employing elliptic curve cryptography and cryptographic accumulator techniques, combined with the CapBAC model, an access control method based on an RSA cryptographic accumulator is designed. This method achieves rapid resource authorization and security control by distributing verification authority tokens on roadside infrastructure.

Benefits of technology

It achieves lightweight and efficient access control in the vehicle-to-everything (V2X) environment, prevents single points of failure, reduces communication latency, supports fine-grained secure access, prevents malicious behavior, and quickly verifies member legitimacy.
