“…In this study, we adopt a group key to protect messages transmitted among n ECs, 𝑛 ≥ 3. Based on the scheme presented in [14] by Gangwar and Sarje, we choose Initial Key Agreement (IKA) [15] which is an extended Diffie-Hellman key exchange protocol. The IKA procedure consists of two stages, Upflow and Downflow.…”

Recently, 5G networks have gradually surrounded our living environments to color our everyday lives and make our daily activities more convenient than before. However, in 5G networks, packet P transmitted from local UPFA of a 5G network, e.g., 5G-A, to UPFB in P’s destination 5G network, e.g., 5G-B, is not secure, even not encrypted, particularly via the Internet, A ≠ B. This conducts a risk of data leakage along the connection established between UPFA and UPFB. To solve this problem, in this study, we propose an architecture that encrypts/decrypts P to prevent it from being attacked. P is encrypted by an edge computer, e.g., ECA in 5G-A before it is sent to its destination, and decrypted by another edge computer, e.g., ECB in 5G-B. In this paper, the scenario includes data transmission between two users or among n-party users, n > 2. For the former, the cryptography systems used are symmetric and asymmetric encryption/decryption approaches. For the n-party scheme, we adopt Initial Key Agreement (IKA) mechanism which employs Upflow and Downflow processes to establish a secret key for all participating ECs. Besides, message authentication code, and time stamp are also utilized to enhance the security level of data transmission. Our analyses show that this proposed approach can effectively avoid some types of attacks.

“…Due to resource constraints secure and efficient group communication in mobile ad hoc networks is a very challenging task, therefore, any proposed group key establishment protocol must be efficient in computation and communication. In [18,19], the authors present a secure and efficient group key agreement protocol for mobile ad hoc network.…”

The recent growth of the World Wide Web has sparked new research into using the Internet for novel types of group communication, like multiparty videoconferencing and real-time streaming. Multicast has the potential to be very useful, but it suffers from many problems like security. To achieve secure multicast communications with the dynamic aspect of group applications due to free membership joins and leaves in addition to member's mobility, key management is one of the most critical problems. So far, a lot of multicast key management schemes have been proposed and most of them are centralized, which have the problem of "one point failure" and that the group controller is the bottleneck of the group. In order to solve these two problems, we propose a Key Management Scheme, using cluster-based End-System Multicast (ESM). The group management is between both 1) the main controller (MRP, Main Rendezvous Point) and the second controllers (CRP, Cluster RP); and 2) the second controllers (CRPs) and its members. So, ESM simplifies the implementation of group communication and is efficient ways to deliver a secure message to a group of recipients in a network as a practical alternative to overcome the difficulty of large scale deployment of traditional IP multicast. In this paper, we analyze different key management schemes and propose a new scheme, namely Advanced Transition/Cluster Key management Scheme (ATCKS) and find it has appropriate performance in security.
