摘要
在无中心、分布式的无线自组网中建立信任关系对于确保网络的安全性至关重要,但是面临许多新的问题和挑战。首先,介绍了在无线自组网中引入信任机制的必要性。然后,阐述了信任的概念和作用。在此基础上,说明了信任建立的方法、信任模型以及信任辅助的安全路由机制。最后,归纳了信任建立机制面临的攻击及应对措施。
Building trust relationship in acentric and distributed wireless self-organizing network (WSON) is vital for ensuring network security, but it still faces many new problems and challenges. In this paper neces-sity of introducing trust schemes in WSON is introduced firstly. Then, concepts and functions of trust are expounded. Based on above elaboration, trust building methods, trust models and trust assisted secure routing schemes are explained. Finally, various attacks faced by trust building scheme are countermeasures are summed up.
