Multiple one-way hash random key pre-distribution protocol in sensor networks

Firstly,a basic multiple one-way hash key distribution protocol was developed based on Leighton Micali protocol.It ensures that all neighbors' nodes can establish secure links,but has poor safety performance.Then a novel key distribution protocol integrating multiple one-way hash with random key pre-distribution was presented.Only one-way hash function is requirement for sensor node,which is very suitable for sensor networks.Compared with other protocols,this one has better performance,which need less computing overhead and can enhance the security.
