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。
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.
