中文摘要：

为解决无线传感反应网络的安全位置服务问题，提出了一种距离无关的安全定位协议——ServLoc定位协议．在该协议中，反应器通过认证消息包、被动接收定位请求、过滤虚假信息等方法进行位置攻击防御，位置匿名和分布地确定传感器节点位置．另外也提出了一种基于表决的位置校验协议——ServLoc校验协议，并对反应器攻击的防御方法进行了初步探讨．分析说明，该协议能够有效地平衡位置欺骗攻击的成功率和定位失效率，并在网络遭受位置攻击时，仍能有效地完成安全位置服务．

英文摘要：

To solve the problem of secure location service, this paper proposes a range-free secure localization protocol--ServLoc localization protocol. By means of authenticating messages, hidden actors passively receiving localization requests and filtering false location reports, etc, ServLoc localization protocol can defend location attacks, keep location in privacy and locate sensor node in a distributive way. In addition, this paper also proposes a voting-based location verification scheme--ServLoc verification protocol and ways to defend actor attacks. The analysis illustrates that ServLoc verification protocol can trade off the security and effective localization problem of WSAN. ServLoc scheme can also effectively provide secure location service, even if the WSANs suffer location attacks.
