Efficient Group Key Agreement on Tree-based Braid Groups

Thanongsak Aneksrup, Pipat Hiranvanichakorn

Abstract


The security issues in ad hoc network are increasingly important. In this paper, we propose a distributed key management what approach by using braid groups and key tree. Without any assumption of prefixed trust relationship between nodes, the proposed method works in a self-organizing way to provide the key management services. The using of the proposed tree-based braid groups has following advantages: (1) the communication cost is minimized to constant time; (2) the complexity of computation is decreased to linear permutation by avoiding modular exponential operation. Our approach is more simple, secure and efficiency for group key management in MANET.
