摘要
在计算机网络环境下 ,密钥的产生和管理是个复杂的问题 .本文利用拉格朗日多项式插值法来讨论密钥的产生问题 ,针对计算机网络管理的层次结构给出了基于密钥片段的多会话密钥产生方法和 (k,w)门陷体制下主密钥的产生方法 ,并对所产生密钥进行了安全分析 .
The generation and management of the key is a complicated problem in computer network. This paper discusses this problem using a Lagrange Polynomial Interpolation Formula, and analyses the security of the generated keys. Multiple session keys and host master key are given based on key pieces and (k,w) threshold scheme in hierarchical structure of computer network .The two kinds of method play a role in decreasing the number of keys and improving the security of the master key.
