Because of the limits of wíreless sensor network, the security is difficult to be solved. A design of security protocol for hier翩 archical wíreless sensor network is proposed. The c1uster-head elect method is adopted in LEACH (lJ algoI抽m and identity authentic创ion of访le c1uster幽heads is added, and dynamic encryption and authentication keys are used to enhance the security. And then some a1goI讪ms of the implementation are discussed.
