A Feasible Key Management Scheme in Adhoc Network

Because of no centralized administration or fixed network infrastructure, there are many difficulties to carry out key management in dynamic and self-organized adhoc network. A new feasible two-layered key management scheme in layered and grouped adhoc network structure is proposed in this paper, which can reduce the calculating overheads and improve communication efficiency. Improved Asmuth-Bloom (n, t) threshold key management scheme is designed, which cut down the data traffic of key management between higher leaders, and the calculating complexity is reduced greatly, hence the key-exchange efficiency is improved.
