Key Predistribution Scheme Based on Hash Chain for WSN
Zheng Kuan-lei · Journal of Yangtze University · 2009
The security of wireless sensor networks(WSN) was mainly through study of key management to ensure.Based on key pre-distribution programs, the current research was the hot spot model of random key pre-distribution, However, facing a potential challenge was not to obtain the desired network connectivity and network security survivability at the same time.This paper presents a hash-based random key pre-distribution chain program, based on cryptography hash function to improve the program’s ability to capture anti-node, enhance network security, it has a smaller memory consumption and consumption of communication.
