Key management scheme based on polynomial and chaos for wireless sensor networks
基于多项式和混沌序列的无线传感器网络密钥管理方案*

Due to the large storage and poor security of current schemes, this paper presented a hybrid key management scheme based on polynomial and chaotic sequence. The scheme reduced the network storage through polynomial to establish a shared key between nodes, and solved safe threshold problem in polynomial scheme by taking the advantage of the sensitivity of chaos on initial value, preventing the leakage of keys. The results indicate that the scheme can provide a high level of security performance, not only saves the network communication resources, but also loweres the storage of nodes.
