混合无线 Mesh网络（hybrid wireless mesh network ，HWMN）是最具实际应用前景的无线Mesh网（wireless mesh networks ，WMNs）结构。然而，HWMN也面临着各种安全威胁，尤其是针对路由和隐私安全的内部攻击的威胁。针对这一问题，结合HWM N的特点，提出了基于动态信誉机制的隐私感知安全路由协议（dynamic reputation based privacy‐aware secure routing protocol ，RPASRP）。 RPASRP实现了动态信誉机制、分级密钥管理协议与路由协议的有机结合，并充分考虑了路由过程中的能量损耗。仿真结果表明，RPASRP能有效抵御内部攻击、实现隐私保护和减少路由能量损耗。

Hybrid wireless mesh network (HWMN) is the most practical architecture in wireless mesh networks (WMNs ) , which provides a fusion of heterogeneous wireless networks , network connectivity and coverage to distributed users in a wide area to support applications in different domains ,such as military ,finance and healthcare .Due to the multi‐hop and decentralized netw ork architecture ,HWMN is susceptible to various security threats ,especially to the internal attacks aiming to the routing and privacy security .However ,existing routing protocols for HWMN cannot ensure the security and protect the user privacy effectively as they are vulnerable to internal attacks . Moreover ,few of them have taken the energy consumption into account at routing .To solve the above problem ,combining with the characters of the HWMN ,this paper proposes a dynamic reputation mechanism based privacy aware secure routing protocol (RPASRP) ,which combines a new dynamic reputation mechanism with the hierarchical key management protocol and hierarchical encryption scheme .Furthermore , the energy consumption is taken into account in the process of routing . Simulation results show that RPASRP can implement the security and privacy protection against the inside attacks more effectively and decrease the energy consumption in the process of routing .
