The protocol for secure and fast transmission for cooperative group framework

The existing key management paradigms cannot deal with these challenges effectively. In this paper, we circumvent these obstacles and propose a novel key management model by close this gap. The new paradigm of traditional broadcast is a hybrid encryption and group key agreement. Such a system, each Member has a single public/secret key pair is created. Members of the public key on the remote to see from safely in an ad hoc way intended any subgroup can broadcast to choose. After this model, we have a plan that is proven safe to instantiate the standard model. Even if all members of the non-intention to collude, do they have any useful information cannot be removed from the messages sent. Public group encryption key is removed, the computation of both overhead and communication costs are independent of the size of the group. A remote cooperative broadcasting group too efficiently and safely is the problem of many new emerging networks. Restricting communication barriers, potential sender group a fully trusted is the unavailability of key generation Center and from Dynamics to overcome a key challenge in designing such a system. In addition, we plan to connect simple yet efficient member deletion/facilitate rekeying and flexible strategies. Its complicity, its continued strong security overhead, and a completely reliable authoritative without relying on its implementation of friendship for many applications is a very promising solution to render our Protocol.
