摘　　要：提出一种新的无线传感器网络安全定位算法SAPIT,它采用锚点身份验证和APIT测试结果安全汇总等安全机制,无需增加额外硬件,解决了传统APIT定位算法极易受劫持节点攻击的问题.对该方法模拟仿真,达到预期效果.In this work, we propose a new range-free approach called SAPIT to secure localization in wireless sensor networks. SAPIT has a secure mechanism of anchor ID authentication and APIT test results safe aggregation. It solves the problem that APIT is easily attacked by compromised nodes, with no need of extra hardware. With the proposed approach, we gain satisfactory simulation results.
