A Survey on Recent Advances in Vehicular Network Security,Trust,and Privacy. Key words: mobile terminal, location privacy, K-anonymity, oblivious transfer In view of the security and effectiveness of the current location privacy protection scheme,we propose a K-anonymous location privacy protection scheme for the mobile terminal.In this scheme,2 K valid dummy locations are obtained from the cloaking regions,and then K-1 better locations are selected from them according to the position entropy,so as to achieve a better anonymous effect.The secure and efficient oblivious transfer protocol is adopted,which avoids the dependence on the trusted anonymous center,improves the scheme's efficiency,and realizes the requirement of querying multiple interest points at one time.Security analysis shows that the scheme not only satisfies the unforgeability,but also resists the playback attack.Meanwhile,simulation indicates that the scheme can improve the execution efficiency,enhance the level of privacy protection,and reduce the communication overhead.
