车联网V2N中的轻量级双向认证与密钥协商
Light-weighted Mutual Authentication and Key Agreement in V2N IoV
摘要
Abstract
Aiming at the scenario of vehicle secure access to application servers in the V2N(vehicle to network)environment,a Kerberos extension protocol is proposed based on the PUF(physical unclonable function).This protocol provides the two-way authentication and key agreement between the vehicle and the remoted application server and ensured the confidentiality and authentication of the V2N data transmission.The CRP(challenge response pair)generated by the PUF is used to replace the password in standard Kerberos to prevent the threats of key leakage caused by physical attacks such as intrusion,semi-intrusion,side-channel attacks,etc.The characteristics of Kerberos's light-weighted two-way authentication protocol can overcome the defects of high calculation complexity and slow speed of the public key authentication algorithms,and effectively provide the secure data transmission between vehicles and application servers.关键词
