An Efficient Certificate-Free Key Distribution Protocol for Secure Group Communication in Grid Environment
Venkatesulu · Journal of Computer Science · 2011
Problem statement: In grid environment, group communication is an important mechanism to realize large-scale information resource sharing.However providing security for group communication in grid environment is very difficult because the group is dynamic in nature.Scalable group re-keying is one of the important issues in secure group communication.These group keys should be updated whenever a member joins/leaves the group to maintain the forward and backward secrecy.Approach: In the recent years, cryptography in grid environment plays an important role that allows secure group communication among members in the dynamic group.Results: Our algorithm for key distribution falls into NP-class.Therefore the key distribution is safe.Conclusion: Performance of the proposed algorithm is computationally efficient and cryptographically strong for message generation and key distribution.
