Efficient Key Management Scheme for Heterogeneous Wireless Sensor Network
Shan Hong · Jisuanji gongcheng · 2010
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.
