“…The previous schemes protecting VANET privacy focus on the identity of the anonymous authentication. Common techniques used in studies include group signature scheme [8][9][10], ring signature scheme [11], ID-based signature scheme [12][13][14][15][16], blind signature [17] or mess-up technology and so on [18][19][20][21].…”

“…Ring signature is similar to a simplified group signature scheme and it uses rules to form a ring, which has anonymity feature. For example, Zhang et al [11] propose a privacy-preserving authentication protocol based on ring signature without bilinear pairings in VANETs. It achieves effective privacy protection and authentication mechanisms and also reduces the computational overhead of signature generation process because of discarding the complex operation of bilinear pairings.…”

Vehicular ad hoc network (VANET) is a traffic application of wireless sensor network, which is also a new mobile ad hoc networks composed of vehicle nodes, roadside units, service providers and other components. In VANET, data is transmitted by the wireless channel, which is subject to potential threat like information leak and data attack due to the openness and sensitivity of the auto organization network itself. How to ensure the identity privacy and trusted communication in VANETs is the key issue to be solved urgently. The existing work usually uses authentication mechanism, but the user's privacy disclosure is inevitable during the authentication process. Some anonymous authentication schemes have been proposed to solve the problem of privacy disclosure regardless of considering anonymity abuse. However, anonymity abuse is also severe in VANET. In view of the above problems, this paper proposes a scheme based on fair blind signature and secret sharing algorithm. By security analysis and experiment, the scheme has been proved to be higher anonymity and higher efficiency.

Vehicular ad hoc networks are traffic applications of the Internet of Things, which are composed of vehicle nodes, roadside units, service providers, and other components. In a vehicular ad hoc network, data transmission and management rely heavily on the wireless channel, which is subject to potential threats such as information leakage and data attacks due to the openness of the automotive network. The construction of a secure and trusted system that does not damage the privacy of vehicular ad hoc networks must be further addressed. Existing works usually focus on the anonymous authentication mechanism but neglect anonymity abuse. Furthermore, they always require a trusted third party as a central authority, which causes some security problems. In view of these problems, this article proposes a scheme that is based on the no-certificate-center algorithm. By security analysis and experiments, the scheme is proved to have higher anonymity and higher efficiency.

The transport message security provided by vehicles in VANETs is quite important; vehicle message should be real-time and it will be not complicated to validate message calculation. The method proposed in the essay is mainly to validate the identity by means of Bilinear Diffie-Hellman method, and make vehicles validate the authenticity of RSU and TA’s identity and the effectiveness of key. RSU and TA only need to validate vehicle identity, without helping vehicles produce any key. When vehicle identity validation is completed, vehicles will produce public value and transmit it to other RSU and vehicles, while other vehicles could validate the identity through the message from the sender and public value from RSU. The advantages of the method proposed in this essay are listed as follows. (1) Vehicles, RSU, and TA can validate mutual identities and the effectiveness of keys. (2) Vehicles can produce public value functions automatically, thus reducing key control risks. (3) Vehicles do not need to show certificates to validate their identities, preventing the certificates from attacking because of long-term exposure. (4) Vehicles adopt a pseudonym ID challenge to validate their own identities during the process of handoff. (5) Vehicle messages can be validated using the Bilinear Diffie-Hellman (BDH) method without waiting for the RSU to validate messages, thus improving the instantaneity of messaging. The method proposed in the essay can satisfy source authentication, message integrity, nonrepudiation, privacy, and conditional untraceability requirements.
