摘      要：Vehicular ad hoc networks(VANETs) create 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 *** design a Certificateless signcryption(CLSC) scheme to provide confidentiality, authentication, integrity, nonrepudiation and user privacy preservation for the information transmitted between vehicle communication *** demonstrate the confidentiality and unforgeability of the proposed scheme in the random oracle ***, 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.
