  • 摘要:Providing security in group communication is more essential in this new network environment. Authentication and Confidentiality are the major concerns in secure group communication. Our proposed approach uses an authenticated group key transfer protocol that relies on trusted key generation center (KGC). KGC computes group pair for each individual and transport the pair of values to all group members in a secured manner. Password based authentication mechanism is used to avoid the illegal member access in a group Also, the proposed approach facilitates efficient key computation technique such that only authorized group members will be able to computer and retrieve the secret key and unauthorized members cannot retrieve the key. The proposed algorithm is more efficient and relies on NP class. In addition, the distribution of key is also safe and secure. Moreover, the pair generated for the computation of key is also very strong since the cryptographic techniques are used which provides efficient computation.
