| 摘 要： | 基于椭圆曲线上多项式的性质,改进了文献[5]中的密钥共享方案,提出了基于多项式形式的椭圆曲线动态密钥共享方案.本方案不仅有效地减少了CA与参与者之间的通信量,而且实现过程中解决了检验子密钥的真伪问题,防止了CA与参与者任何一方的欺诈行为.两种方案的安全性都是基于椭圆曲线离散对数问题的难解性.

| Abstract: | Based on properties of polynomials over elliptic curve,this paper presented a dynamic secret sharing scheme based on polynomials,an improvement of scheme in reference [5] and reduced the communication between CA and participants.Furthermore,this scheme is able to check the validity of the sub-secret keys easily and then avoid cheat from either CA or participants efficiently.Both of their security are based on the intractability of elliptic curve discrete logarithm problem. |

| Keywords: | polynomial dynamic secret sharing scheme sub-key elliptic curve discrete logarithm problem |
