| 摘 要： | 对灰色加密理论中的多用户双锁加密系统进行了改进,提出了一种基于多用户双锁加密系统的密钥分存方案.该方案通过改变灰色微分方程x(0)(k) az(1)(k)=b中z(1)(k)的生成系数(权数),解决了密钥分存中密钥的更新和复用问题,并通过引入一简单的离散对数函数来抵御成员欺骗.

| Abstract: | The multiuser both-lock encryption system of grey encryption theory is improved and a secret sharing scheme based on both-lock encryption system is put forward.The scheme modified the generation modulus of 1 in grey differential coefficient equation: 0 + 1 = to resolve the updating and reusing of key in sharing scheme and against participant cheating by a simple discrete loga-rithm function. |
