摘要
密钥管理是无线传感器网络安全的一个重要组成部分,近来,密钥管理的研究受到广泛的关注,提出了很多密钥的建立和管理的方案。受到传感器节点能量的限制,所提出的方案必须最大限度的做到节能。因此,本文提出了一种基于椭圆曲线的加密方案。该方案中原始密钥链的计算和密钥的更新阶段都是在基站中完成,大大降低了节点能量的消耗。
Key management is one of the most important part of wilrelss sensor networks.Resently,it receives widespread attention,many key distribution schemes have been proposed.Given the pover constrait of sensor nodes,the proposed scheme should reduce the energy consuming mostly.Thus,this paper proposes an encryption scheme based on elliptic curves in wireless sensor networks,in this scheme,the raw key chain and key updating are computed in base station,and greatly reduces the energy consuming.
