Secure group communication over MANET using hybrid Key Management

In many newly emerging network there is a need to provide secure transmission within the network.MANET is one such network which requires secure group communication.The key concept in security is key management.In the existing key management systems third party is fully trusted for key generation.Hence the trustworthiness of third party is more important to provide secure communication.Here we propose a hybrid approach which combines group key agreement and broadcast based encryption techniques.The major advantage is that it avoids the need to rely fully on a trusted third party.Here we use a provable secure protocol which provides resistance against blackhole attack such that secure and efficient routes will be provided to reach the destination.Thus the new paradigm facilitates a fast and secure transmission to remote groups.
