Internet of vehicles security authentication device and method

Abstract

The invention discloses an Internet of vehicles security authentication device and method. The method comprises the following steps of organically combining traditional cryptography authentication service with a trust evaluation mechanism, realizing the traditional cryptography authentication service and the trust evaluation mechanism according to an interface provided by an authentication performance device, mounting the traditional cryptography authentication service and the trust evaluation mechanism to the device, externally providing call service through a uniform interface of the device, and shielding realization details of various complex authentication algorithms; deploying a trusted embedded security module on a vehicle node in a sensing layer, thereby providing security capability, and modularizing an encryption algorithm of the sensing layer; establishing an authentication system integrated with a trusted terminal, a cryptography authentication method and the trust evaluation system; and matching and evaluating a high-security trusted evidence factor provided by a bottom sensing layer and providing authentication decision basis for an upper traffic information service platform.
