Due to the inherent characteristics of wireless sensor networks itself and the features of deployment environment,its security is facing huge challenges.On the other hand,the routing protocol focuses on the transmission efficiency and energy consumption when designing,but does not give much attention to information security,so it is vulnerable to various attacks.Secure multi-path routing protocol is an important technology to ensure the security of WSNs.We studied the secure multi-path routing protocols of WSNs in recent years,and divided the secure multi-path routing protocols into three categories according to the nature of defense against the WSN attacks,and analysed the security technology of the each typical security technology.In end of the paper we point out the research directions of WSNs secure multi-path routing protocol in the future.%由于无线传感器网络 WSNs 自身特性及部署环境特点，其安全面临巨大挑战。另一方面，路由协议设计关注于传输效率与能量消耗，信息安全没有引起足够的重视，易遭受多种攻击。安全多径路由协议是一种保证 WSNs 安全的重要技术，研究近年来WSNs 安全多径路由协议，根据协议攻击防御的特性，把安全多径路由协议分为三类，并对每类典型协议安全技术进行分析，最后指出安全多径路由协议未来研究方向。
