摘要: 本文针对无线传感器网络的用户认证问题给出了一套分布式的认证方案。此方案利用自我验证密码系统(self-certified key cryptosystems)来建立对等密钥,在对等密钥建立的基础上给出了两种不同类型的认证:本地认证和远端认证。我们的认证方案不但具有很强的安全性,而且由于具有较低的通信与计算代价,从而很容易在传感器网络中实现。

Abstract: This paper presents a distributed user authentication scheme in wireless sensor networks. Our scheme utilizes the self-certified keys cryptosystem (SCK) to establish pair-wise keys. Based on these keys we propose two different kinds of user authentication scheme: local user authentication and remote user authentication. Our proposed user authentication scheme imposes very light computational and communication overhead, and our analysis also shows that our scheme is feasible for the real wireless sensor networks.
