An implementation of anonymous authentication system in wireless sensor network using vlr group signature

Disseminating sensory information from sensor nodes to the gateway node towards Data Center Server has to be guaranteed its fruitfulness. However, these important information commonly are transmitted over wireless connections whereas everyone including adversaries may join freely in the network. Hence, the correctness of received information should be emphasized. To do so, such information should be ascertained from the authenticated sensor nodes, kept its secrecy, prevented from the alteration, and guaranteed its integrity, respectively without revealing sensor nodes' identity. On the other hand, data sensors in the Data Center Server also should be kept secret and only be accessed by authenticated users over common public connection such as Internet without exposing the users' privacy. Therefore, an anonymous authentication system in collecting data sensors from sensor nodes to the Data Center Server and accessing them by everyone would be strongly desirable. In this paper, we propose an implementation of anonymous authentication system in the wireless sensor network using VLR group signature.
