A Novel Computationally Efficient Group Signature for Anonymous and Secure V2X Communications. (arXiv:2307.13759v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The use of vehicle-to-everything (V2X) communication is expected to
significantly improve road safety and traffic management. We present an
efficient protocol, called the AEE protocol, for protecting data authenticity
and user privacy in V2X applications. Our protocol provides event-based
likability, which enables messages from a subject vehicle to be linked to a
specific event in order to prevent Sybil attacks. Messages on different events
are unlinkable to preserve the long-term privacy of vehicles. Moreover, our
protocol introduces a new method …
