摘要
基于有限域上离散对数难解问题提出一个计算安全的动态秘密分享方案 ,本方案有效地解决了密钥的翻新与复用问题 ,其效率高且实用 ,特别是能检测伪子密 ,防止欺诈 ,且数据利用率较高。
A dynamic secret sharing scheme with providing computational security to identify cheaters,which is based on the computational difficulty of computing discrete logarithms,is proposed in this paper The renew and reuse problems are properly treated in the scheme The scheme is efficient and practical,in particularly,which can detect the cheaters,and the data in the scheme are sufficiently used
