Simulation of two-way security authentication algorithm for wireless sensor network nodes
Generally,wireless sensor networks are composed of many nodes deployed in a distributed manner.However,they are susceptible to malicious attacks.In order to ensure that nodes can provide high-security data infor-mation services and higher privacy protection,as well as secure data query services for legitimate enquirers,this article presented a bidirectional authentication algorithm for wireless sensor network nodes with high security.Based on the Wireless Sensor Network(WSN)energy model,WSN nodes were divided into different clusters,thus reducing node energy consumption.After that,network initialization,key negotiation,and node trust calculation were performed on the clustered nodes to obtain trusted nodes.Moreover,digital signatures were adopted to achieve bidirectional au-thentication between trusted nodes.Finally,the security of wireless sensor networks was improved.Experimental results show that the proposed method can effectively improve the survival circle of WSN nodes while reducing authen-tication latency and energy consumption.
