摘要
通过结合椭圆曲线密码(ECC)和可公开验证秘密共享(PVSS),提出一种新的多方秘密共享方案。该方案不需要参与者之间存在秘密通道,通信在公共信道上进行,且认证过程是非交互的,除了能够有效防止管理者和参与者欺骗以外,还能够忍受管理者攻击,具有更好的安全性、鲁棒性和高效性。
Through the combination of elliptic curve cryptography （ECC） and publicly verified secret sharing （PVSS）, a novel noninteractive multi-party secret sharing scheme is proposed. In this scheme, there is no need to build a secret channel, the participants can communicate in a public channel, and the certification process is non-interactive. It can protect against the distributor＇s cheat and the participants＇ cheat, moreover, it can tolerate the distributor＇s attack, and show much better security, robustness and efficiency.
