On the Xiao′s key distribution scheme for the shipping communication

通过引入可信第三方权威认证机构,基于有限域上的椭圆曲线离散对数问题的求解困难性,提出并在嵌入式环境下实现了一种简单实用的高效密钥分配协议XKDS,并对其进行了分析,提出了实现和维护的方法。

In this paper, a new key distribution scheme in the embedded environment named Xiao＇s key distribution scheme （XKDS） is proposed based on the difficulty on solving the elliptic curve discrete logarithm problem in the finite groups, which is simple, effective and safe, and can be applied in many domains. The authors also discuss about the ways of implementation and maintenance of the XKDS scheme.
