An anonymous authentication system in wireless networks using verifier-local revocation group signature scheme

As advancement of the Internet of Thing and data centric technologies in collecting and distributing sensory data, security becomes much more important and desirable. This is because sensory data are commonly transmitted over wireless networks toward data center which are naturally easily observed for the goal of network traffic analysis. Furthermore, the collected data in data center can be easily accessed by users as well if the system does not deal with security mechanism. In this paper, we propose an anonymous authentication system using pairing-based verifier-local revocation group signature scheme to authenticate wireless nodes (i.e., sensor nodes) of a particular privilege group to the gateway node in transmitting data. In addition, an anonymous authentication for accessing data to the data center is also our achievement.
