This paper puts forward a secure scheme to establish the session key between communication parties by use of binary symmetric polynomials,considering the hierarchical Wireless Sensor Networks(WSN) update.This scheme can guarantee the confidentiality and integrity of the message transmission,and can effectively resist the attacker's illegal tampering,replacement and replay to the message.Moreover,this scheme supports the session key update between communication parties and can enhance the authentication to the node identity so as to prevent the spoofing attack of the illegal nodes.Analysis shows that this scheme is more secure than others,and has reasonableness of cost and efficiency.
