Research on Authentication Strategy in Wireless Sensor Network
无线传感器网络认证机制的研究

With the wireless sensor networks infiltrating in each field of our life,the security mechanism has already become one of the main reasons of restricting its development.As authentication is an important part in the security mechanism,it is significant to study the authentication mechanism of wireless sensor networks.On the basis of analyzing the inside security and the outside security that wireless sensor networks are facing,entity authentication and information authentication of the secu-rity tactics are analyzed.Besides the corresponding authentication scheme aiming at different security problems is described.Via analyzing a sort of existing authentication schemes,several conception of research authentication mechanisms are pointed out.
