Key management scheme in WSN based on secret message

Key pre-distribution management scheme should do the best to reduce the message pre-storage in sinks under the premise:high security,strong key agreement,less communication,less computation complexity.Key pre-distribution management scheme based on secret message is in order to solve this problem.In this scheme,sensor generates the safe session key with its near sensors only need communicate with the base station once.So it is suitable for the abundance of sensors network.After comparative analysis,this scheme has advantages in security,key agreement,communication compare to the q-composite scheme.
