Abstract：When obtaining node data through user identification in wireless sensor networks, passwords may be cracked and some other security problems such as being prone to network attacks may occur. Concerning these problems and based on the improved Das'protocols of two-factor user authentication, UAPL protocol was proposed after introducing a verification mechanism between users and gateway nodes as well as between gateway nodes and sensor nodes, and a mechanism for changing's password. This protocol had security features that prevented gateway node sideway attacks, masked attacks and other network attacks and its provided capability of password change protection could prevent security problems when passwords were leaked out. The experimental results show UAPL protocol offers much higher security than other improved Das'protocols.
