“…CA). Several group signatures have been proposed (Ateniese et al, 2000;Bresson and Stern, 2001;Song, 2001;Ateniese and Tsudik, 2002;Goh and Jarecki, 2003;Popescu et al, 2003;Boneh et al, 2004;Camenisch and Groth, 2005). All these research works are proved secure under certain theoretical assumptions such as strong RSA assumption and strong Diffie-Hellman assumption.…”

“…Unlinkability is a property that must be met in communication protocols that provide anonymity. Signatures are unlinkable if it is computationally hard to decide whether any two different signatures have been computed and produced by the same person (Ateniese and Tsudik, 2002;Popescu et al, 2003). Assume in our protocol that i j M generates two…”

In Vehicle-to-Vehicle (V2V) communication networks, vehicles broadcast their safety-critical information to alert nearby vehicles of possible collisions. It is necessary to provide secure wireless communications for V2V safety applications to prevent unauthorised entities from tampering with the broadcast data. A Certificate Authority (CA) can provide trust and secure communications among drivers in V2V networks. However, the disclosure of drivers' unique public keys from their certificates will allow unauthorised entities to trace drivers' movements and locations they visit. Revealing such information without consent from drivers is a violation of their privacy. In this paper, we propose a broadcast protocol for V2V safety applications that provides anonymity for drivers. In our scheme, drivers frequently change their public keys using the digital signature algorithm. The CA is not required to authenticate the generated public keys. The recipients of a signed message can verify the correctness of the signature without identifying the signer.

protecting the privacy of message receivers is an important issue in pay services of e-commerce and the distribution of digital contents on the Internet. This paper proposes an efficient privacy of message encryption algorithm called PMEA for pay services of e-commerce. In PMEA, each of the receivers only needs to perform constant times of pairing computation to decrypt the received message. PMEA adopts bilinear pairings on elliptic curves to protect the privacy of message receivers, to ensure that an attacker or any other message receiver can not derive the identity of a message receiver such that the privacy of every receiver can be guaranteed. Detailed theoretical analysis proves that PMEA is secure and anonymous for message receivers.
