Key pre-distribution scheme based on chaos in wireless sensor network
无线传感器网络中基于混沌的密钥预分配方案

To increase the security of Wireless Sensor Network (WSN), reduce the energy consumption and prolong the lifecycle of the system, a chaos scheme of key pre-distribution was put forward. In this scheme, the ergodicity of chaos was used to avoid the key of being decrypted, and chaos initial value sensitivity was used to ensure the key could be altered safely in communications. The analysis shows that the scheme can provide larger key space and the cost in communication and computation are smaller, thus it has stronger practicality.
