车载自组网中信任感知的隐私保护策略
Trust-aware privacy-preserving scheme for VANET
摘要
Abstract
The trust management systems in Vehicular Ad-hoc Networks(VANETs)require users to disclose their reputa-tion-related information,which will bring dangers to user privacy.To deal with the collusion between trust and privacy,a novel"pseudonym-reputation"collaborative change scheme is presented in this paper.This scheme is based on the k-anonymity theory and user-centric strategy.The personalized privacy protection is considered and a PK-PCS strategy is presented. Experiments show that the PK-PCS strategy is better than the traditional Pseudonym Change Strategy(PCS) strategy and K-anonymity Pseudonym Change Strategy(K-PCS)strategy in privacy preservation, satisfaction and data loss.The PK-PCS not only maintains the usefulness of trust,but also protects the privacy of users.关键词
