无线传感网络密钥管理及认证综述

Survey of Sensor Networks Key Management and Authentication

无线传感器网络因其灵活性和适用性而广泛应用于民用、军用、商用等领域,然而由于传感器结点自身的特点使得无线传感器网络与传统网络有着很大的不同。对有安全性要求的无线传感器网络而言,若在敌对环境中使传感器网络结点间能安全地进行通信,密钥管理和认证就显得十分重要。目前针对密钥管理和认证提出了许多方案,对这些方案做出了总结并给出了比较,同时对进一步的研究方向进行了分析。

Because of the flexibility and extensive applicability of the wireless sensor networks, they can be applied into many fields such as civil, commercial and military. Based on nodes＇ characters, the sensor networks are quite different from the traditional networks. The key management and authentication are important to guarantee nodes＇ secure com- munication. Now there ＇ re many schemes for key management and authentication, in this paper the current schemes were classified and compared,also the future studying directions were pointed out.
