Vehicular Ad hoc Networks ( VANETs) are essential for the Internet of Things. However,criminals exploit public channels to eavesdrop on and manipulate messages,potentially gaining control over vehicles and leading to security threats such as accidents and privacy breaches. To address the is-sues,in this paper a certificate-less lightweight identity authentication scheme named Light-V2X is de-veloped based on the SM2 public cryptographic algorithm,where ECDH key negotiation and pseudonym authentication technologies are integrated to streamline multi-party authentication in specific areas to en-hance the communication efficiency. Informal security analysis,formal security demonstrations in the ROR model,simulation experiments employing the AVISPA tool and horizontal performance compari-sons with alternative solutions indicate that our scheme has high performance and low cost.
