- Abstract
Privacy protection is an important requirement in vehicle networks. Meanwhile, privacy requires to be disclosed when a traffic accident happens. So the paper presented a traceable privacy protection scheme. In existing schemes the issues about authority forgery and authority leaks remained unresolved. So using the oblivious transfer protocol, the manage authority issued private keys. Based on secret sharing scheme, tracking authorities collaboratively revealed identities. It used the methods of group signature, batch verification and preprocessing revocation efficiently in anonymous communication. Security analysis shows that the scheme is superior to the existing schemes in terms of unforgeability and robustness. Performance analysis shows that the cost of communication and computation is similar to the existing schemes. So it will have effective applications in VANET.
