Research on Secure Communication Scheme of Clustered WSN Based on Dynamic Key
The openness of the wireless channel makes wireless sensor networks vulnerable to external attack.In order to ensure the integrity and privacy of data transmission in wireless sensor network,by analyzing the existing security communication schemes,this paper propose a security communication scheme which adopts symmetric matrix and symmetric polynomials to realize dynamic key management in clustered wireless sensor networks,and adopts the authenticated encryption algorithm in the network layer to achieve confidentiality and integrity in information transmission.The session key generates dynamically without communication interaction,solves the deficiencies of security and connectivity in symmetric key management,and achieves high efficiency of key distribution and dynamic updating.
