Efficient anonymous authentication protocol for internet of vehicles based on Chinese cryptographic SM2
摘要
Abstract
A critical component of cybersecurity protection in the internet of vehicles(IoV)was identity authentica-tion.However,many existing authentication schemes were plagued by low efficiency and incompatibility with do-mestic cryptographic algorithms.To further enhance authentication efficiency and expand the application of domes-tic cryptographic algorithms in the IoV domain,an anonymous handover authentication protocol was designed based on the Chinese national cryptographic SM2 algorithm.A pseudo-identity authentication mechanism was inte-grated into the protocol to strengthen the protection of vehicle privacy information,effectively concealing vehicles'real identities and operational data.Domestic cryptographic algorithms were incorporated into the protocol,which also demonstrated superior performance in authentication efficiency.In densely vehicle environments,an innova-tive batch authentication algorithm was employed by the protocol.To validate the protocol's performance,tests of the batch authentication algorithm were conducted on a QT platform based on the Fedora system,with the batch au-thentication efficiency for 10,20,40,⋯,320 vehicles being evaluated.As the number of authenticated vehicles in-creased,the efficiency advantages of the batch authentication algorithm became more pronounced.When authenti-cating 320 vehicles,the road side unit(RSU)verification efficiency improved by approximately 65%,significantly alleviating the concurrent authentication pressure on RSUs.Both theoretical analyses and experiments using the AVISPA tool confirm that the proposed protocol offers enhanced advantages in the autonomous controllability of IoV security.It not only effectively resists replay attacks and man-in-the-middle attacks but also achieves signifi-cant improvements in authentication efficiency,thus providing a more secure and effective identity authentication solution for IoV systems.关键词
