Abstract: The basic function of wireless sensor network is to detect and report the position where the event happen，so location information and locating process are very important.Energy and accurate are more cared and security is ignored in location approaches in the past.Recently，the security in location is followed with interest.In this paper，the possible threaten in location and the securities in traditional location algorithm are analyzed，the exited secure location algorithm and location Verify are introduced，and the future works are proposed.

Key words: Wireless Sensor Network, location, location verifying, security

摘要： 无线传感网络的基本功能是检测和报告事件发生的位置，所以位置发现很重要。在以前的定位协议设计过程中，只注重能耗和精度问题而忽略安全，近来定位过程中的安全问题引起了关注。分析了定位过程中可能存在的威胁，对传统的定位算法进行了安全分析，介绍了已有的安全定位算法和检测方法，并对将来的研究提出了初步的设想。
