In this section we introduce the four basic protocols that form the TGDH protocol suite: join, leave, merge, and partition. All protocols share a common framework with the following notable features:
Group Key Agreement with Local ConnectivityGroup Key Agreement • February 11th, 2017
Abstract: In this paper, we study Group key agreement means multiple parties want to create a common secret key to be used to exchange information securely. The group key agreement with an arbitrary connectivity graph, where each user is only aware of his neighbor and has no information about the existence of other users. Further, he has no information about the network topology. We implement the existing system with more time efficient manner and provide a multicast key generation server which is expected in future scope by current authors. We replace the Diffie Hellman key exchange protocol by a new multicast key exchange protocol that can work with one to one and one to many functionality. We also tend to implement a strong symmetric encryption for improving file security in the system.

Abstract :-Key agreement is a mechanism that allows two or more parties to securely share a secret key (called a session key). Starting from Diffie-Hellman for the two-party case. However, almost all the protocols assume a complete connectivity graph: any two users can communicate directly. In the real world, this is not always true. For instance, in social networks such as Face book, Skype, Wechat and Google+, a user is only connected with his friends. For a group of users (e.g., the faculty union in a university) who wish to establish a session key, it is not necessary that any two of them are friends. But they might still be connected indirectly through the friend network. Of course, we can still regard them as directly connected by regarding the intermediate users as routers. However, this is quite different from a direct connection. First, indirectly connected users may not have the public information of each other (e.g., public-key certificate). Second, indirectly connected users

MUTUAL AUTHENTICATION AND GROUP KEY AGREEMENT FOR LOW-POWER MOBILE DEVICESGroup Key Agreement • April 15th, 2004
Wireless networking has the power to fit the Internet with wings, however, it will not take off until the security technological hurdles have been overcome. In this paper we propose a very efficient and provably-secure group key agreement well suited for unbalanced networks consisting of devices with strict power consumption restrictions and wireless gateways with less stringent restrictions. Our method meets practicability, simplicity, and strong notions of security.

In particular, recent dramatic advances in computing power motivate a priority shift. As computation becomes faster, communication speeds do not enjoy similar advances and communication latency, especially in high-delay long-haul networks increasingly dominates protocol costs, replacing in some cases computation as the main latency factor. Hence, there is a need to minimize the number of messages, their size and the number of rounds in cryptographic protocols.

Abstract: In this paper, we consider Group key assention suggests distinctive social affairs need to make a run of the mill puzzle key to be used to exchange information securely. The social event key simultaneousness with a self-confident accessibility outline, where each customer is only aware of his neighbor and has no information about the vicinity of various customers. Further, he has no information about the framework topology. We execute the present structure with extra time beneficial way and give a multicast key time server which is ordinary in future expansion by current makers. We supplant the Diffie Hellman key exchange tradition by another multicast key exchange tradition that can work with adjusted and one to various helpfulness. We in like manner have a tendency to execute a strong symmetric encryption for upgrading archive security in the system.
