摘要

Vehicular ad hoe networks (VANETs) cre-ate an vital platform for communication between vehicles,which can realize accident warning,auxiliary driving,road traffic information query,passenger communication and other applications.While providing convenient services for people,VANETs also bring some security risks.Security and privacy are the primary issues in the research of VANETs.Signcryption is an ideal way to transfer messages in a logical step in a secure and authenticated way.We design a Certificateless signcryption (CLSC) scheme to provide confidentiality,authentication,integrity,non-repudiation and user privacy preservation for the infor-mation transmitted between vehicle communication units.We demonstrate the confidentiality and unforgeability of the proposed scheme in the random oracle model.Moreover,compared with the existing CLSC schemes,ours realizes the perfect combination of efficiency,security and privacy,and it is particularly well adapted to the secure communication of vehicle networks.
