Abstract

Abstract: A dynamic secret sharing scheme based on elliptic curve cryptosystem is proposed. In the new scheme, the participants can update sub secret share easily and dynamic manage flexibly, which realizes the dynamic management of group members. A secure channel among all the members is not needed because of using signcryption algorithm on elliptic curve in the system, which ensures the security and practical of the scheme.

Key words: secret sharing, signcryption algorithm, elliptic curve discrete logarithm problem, Lagrange interpolation

摘要： 基于椭圆曲线密码体制提出一个动态秘密共享方案。新方案具有系统参与者子秘密份额更新容易、参与者动态管理灵活的特点，实现了组成员的动态管理。通过椭圆曲线上的签密算法，使系统各个成员之间的通信不需要安全信道，从而保证了方案的安全性和实用性。
