Abstract

An emerging technology is Wireless Sensor Network where sensors are deployed at extreme geographical locations where human intervention is not possible. The data transferred through the sensor nodes are majorly used in crucial decision making process. Since WSN is a wireless infrastructure it tempts the attackers to tamper/misuse the data. Privacy-preserving routing is important for some ad hoc networks that require stronger privacy protection. Hence a routing protocol to achieve total unobservability by anonymous key establishment using secret session keys and group signature is used. The unobservable routing protocol is divided into two main phases. First phases define an anonymous key establishment process to construct secret session keys. Second phase consist of unobservable route discovery process to find appropriate as well as secure route to the destination. A node establishes a key with its direct neighbour and uses the same key to encrypt the packet before transferring.
