Research On Wireless Sensor Network Anonymous Communication Algorithm

Since the 21 st century,wireless sensor technology has been developed rapidly and applied to so many aspects of the society.With the widely use of the wireless sensor network,the security problem are increasingly highlighted.There are more and more researchers pay attentions to the security problems and started the security study of WSN.The security problems of WSN include communication security,the BS security and sensor node security and so on.In recent years,the researchers also keep eyes on the privacy security problems of the WSN.Anonymous communication and authentication technology were the strategies of protecting communication security and privacy security.In the past few years,security researchers have paid much attention on these strategies.After fully study of the security problems of the WSN,we proposed an anonymous communication scheme and authentication algorithm respectively.These two schemes could improve the security performance of WSN.The research content of this paper are as follows:Anonymous communication scheme: The scheme was proposed for the clustered WSN.In the scheme we first constructed the frame of the whole communication process.We divided the communication process into two stages,namely the communication within a cluster and communication between clusters.They could provide the privacy protection of cluster member nodes and clusters.In order to verify the effectiveness of the proposed algorithm,we analyzed the anonymity degree of our scheme using entropy based method.And then we valuated its performance using NS2 simulation.Authentication scheme: Our scheme is based on one way hash function and during the authentication process we introduced the idea of fake id which in the former anonymous communication scheme we proposed.This formed the concept of anonymous authentication.We analyzed the security of the scheme and also compared with other schemes,it implies that our scheme can provide good security protection.The theoretical study and comparison with other schemes implied that our scheme could provide good privacy protection.And it won't bring much energy consumption.
