Key pre-distribution scheme for wireless sensor networks based on Hash function
Haifeng Xu · Journal of Computer Applications · 2007
Key distribution plays a fundamental role in Wireless Sensor Networks(WSN).A key pre-distributing protocol based on Hash function was proposed,which extended the ideas of the probabilistic key pre-distribution scheme put forward by Echenaue and Gligor.In this scheme,some of the pre-distribution keys in the nodes were computed by Hash function.With the advantage of one-way Hash function,this scheme could enhance the ability of network to resist attacks.Compared with other schemes,this one has less computing overhead and higher security performance,which is more suitable for WSN.
