Abstract


This paper briefly introduces the concept of wireless sensor networks and currently use a variety of key management schemes , the focus of sensor network security features , for there is no actuator actuator nodes and two types of wireless sensor network nodes have proposed their own the key distribution scheme : there actuator nodes for wireless sensor networks based actuator node has a strong anti- attack capability, computing power and network node deployment actuator nodes were higher on the ability to control , according to their needs with the implementation of proposed node 's key distribution scheme ; random cluster head for wireless sensor networks presents EG model and C.Blundo polynomial model combines key distribution scheme , and set up multi-channel safety barriers to prevent the key from being cracked. Papers on the key distribution model performance evaluation and analysis , a strong focus on security and anti- node connectivity rate captured immunity. The results show that , with the implementation of key distribution model node connectivity rate in the security and anti- nodes are captured immunity are satisfactory. On randomly selected cluster head sensor network , select the appropriate polynomial pool size S and each node selected polynomial number m can reach the ideal secure connectivity rate . This paper analyzes the captured nodes on the network security threats resulting derived probability secure link to be cracked and captured the relationship between the number of nodes and specific examples are analyzed. The results show that the probability of a secure link to be cracked very low , and if they take further multi-channel safety barrier , its security is reassuring .
