摘要
文章给出了一个基于椭圆曲线公钥密码体制的动态秘密共享方案,有效地解决了共享秘密的动态更新、子密钥动态分配和防欺诈问题,且易于实现、效率高。方案的安全性基于求解有限域上椭圆曲线离散对数的困难性。
Based on Ellipse Curve Cryptosystem,a dynamic secret sharing scheme is presented in this paper. The problem of renew shared secret,dynamic sub- secret allocation and detection of cheaters are properly treated in the scheme. The scheme is efficient and practical,and its security is based on the difficulty of computing ellipse curve discrete logarithms problem.
