异构无线传感器网络高效密钥管理方案

在分析现有密钥管理方案的基础上，提出一种异构无线传感器网络密钥管理方案，该方案为H-Sensor和L-Sensor产生不同数目的密钥链生成值，采用散列函数与密钥链生成值迭代生成密钥链，通过产生的密钥链和迭代次数运用分组链接技术构造会话密钥。分析表明，该方案能够利用较低的存储负载获得较高的密钥连通性，同时提高整个网络的安全性能。

Efficient Key Management Scheme for Heterogeneous Wireless Sensor Network

This paper proposes a key management scheme for Heterogeneous Wireless Sensor Network(HWSN). The scheme generates different numbers of key chain generation for H-Sensor and L-Sensor. The key chain is built by Hash function and key chain generation. After that, it takes cipher block chaining to build a session key by using generated key chain and recursion number. Theoretic studies show that the scheme needs less storage payload to get more key connectivity and has the ability to solve the security problem after mass nodes are compromised.
