摘要：
本文提出了一个基于椭圆曲线密码体制（ECC）的、定期更新的可验证的秘密共享方案.该方案具有子秘密定期更新、子秘密可验证和可防欺诈的特点.方案的安全性基于求解 有限域上椭圆曲线离散对数问题（ECDLP）的难解性.
关键词: 椭圆曲线密码体制 秘密共享 定期更新 可验证秘密共享
Abstract:
Based on the elliptic curve cryptosystem, a verifiable secret sharing scheme is presented. Sub-secrets are renewed periodically and can be verified by all the participants in this scheme The scheme is cheating-immune and its high security is based on the intractability of computing the elliptic curve ＇s discrete logarithm problem.
Key words: elliptic curve cryptosystem, secret sharing periodically renewed verifiable secret sharing
