%X In order to realize secure mobile node authentication in vehicle Ad hoc networks(VANET),this paper proposed a scheme consisting of identity-based cryptographic algorithms,secret sharing distributed algorithms and XTR public key cryptosystem to achieve safe and efficient traffic nodes certification.This algorithrn used Lagrange interpolating polynomial to distribute master secret key among system nodes,and presented a distributed procedure to securely issue node key based on the XTR system tracks algorithm.This paper discussed identity-based digital signature algorithm on the XTR cryptosystem briefly.And used the concept of the credibility of the value to find and eliminate malicious nodes in the networks.After analyzing the security and efficiency of the proposed algorithm, the mechanism would apply to vehicles distributed mobile network environments.
