With the rapid development of mobile networks, there are more and more application scenarios that require group communication. For example, in mobile edge computing, group communication can be used to transmit messages to all group members with minimal resources. The group key directly affects the security of the group communication. Most existing group key agreement protocols are often flawed in performance, scalability, forward or backward secrecy, or single node failure. Therefore, this paper proposes a blockchain-based authentication and dynamic group key agreement protocol. With our protocol, each group member only needs to authenticate its left neighbor once to complete the authentication, which improved authentication efficiency. In addition, our protocol guarantees the forward secrecy of group members after joining the group and the backward secrecy of group members after leaving the group. Based on blockchain technology, we solve the problem of single node failure. Furthermore, we use mathematics to prove the correctness and security of our protocol, and the comparison to related protocols shows that our protocol reduces computation and communication costs.

Cloud Computing is a service oriented computing technology, is allows a group of people to work together and access data resources. Multi privileged Group key management has becoming a big challenging issue in the field of cloud data sharing. We have different group key management protocols which are distributed and centralized. But these protocols have drawbacks of single point of failure and bottleneck performance. Decentralized key management schemes proposed as trade-off between them. This paper proposes a Decentralized key management scheme using alternating multi linear forms for cloud data sharing with dynamic multi privileged groups. This method is to divide large group into many subgroups, each sub group has a group manager. Group manager manages the group, and keys are first distributed to the GM (Group Manger) and then GM can distribute to users in respective groups. The related session keys ought to be updates, if any cloud user needs to join/leave the group and change their privileges. But user joining/leaving the group as often as possible, users will change their entrance benefits called switching between various SGs. The proposed method needs just a single round of transaction for each leaving/Switching activity. This method also supports the dynamic formation and decomposition of Cloud service Groups. The analysis of proposed method is secure and has Reduces the Computational cost compared to existing scheme.

“…Shared key agreement protocol is an important key protocol, every group member consults shared key with key agreement protocol on public channel [1,2], the method can build security channel in semi honest networks and is suitable to distributed network [3], such as sensor networks [4], Ad Hoc networks [5,6],underwater networks [7], flying Ad Hoc networks [8]. With the improvement of the hardware capability of network members, the delay overhead is restricted by the speed of signal transmission, more interactions incur more time delay, thus reducing the time delay becomes the primary goal of group key management [9].…”

Shared key protocol is an important research issue in distributed networks security. The most existing shared key protocols are based on the discrete logarithm or large number decomposition problem. Those protocols’ cost is related to the network scale, and has the problem of high computation cost and message overhead. To solve the question, this paper proposes a shared key agreement protocol based on the lattice key mechanism (sNTRU). All network members share the key material via public channel, after execution those members has a shared encryption key and a number of different decryption keys satisfying the key independence. Compared with the traditional shared key agreement protocol based on DLP or RSA problem, this scheme only needs one round of interaction, and it is more efficient in calculation cost. In security aspect, its security proof can be reduced to the shortest vector difficulty problem, and it can resist the chosen plaintext attack, forwards security and backwards security are guaranteed.
