Abstract

To provide effective privacy protection in ad hoc networks, there are a number of anonymous routing schemes have been proposed. But these schemes provide significant computation overhead. The existing system introduces USOR, an efficient privacy preserving routing protocol that achieves content unobservability by using anonymous key establishment based on group signature. Here each node having a group signature signing key and an ID-based private key from an offline key server or by a key management scheme. The unobservable routing protocol is then executed in three phases such as anonymous key establishment process, privacy preserving route discovery and unobservable data packet transmission process in order to construct secret session keys as well as finding route to the destination. The USOR scheme protect packet’s content independent of traffic pattern unobservability which can be used with appropriate traffic padding schemes to achieve truly communication unobservability. The proposed system have the intention of developing unobservable routing scheme resistant against sybil attacks, collusion attack and an external attack. It discovers malicious nodes during route discovery process when they mitigate fabricated routing information to attract the source node to send data through malformed packet.
