摘要
基于门限签名算法和变色龙哈希函数,提出了一种新的在线/离线门限签名方案,其安全性完全基于离散对数假设。该方案能容忍t〈n/3个恶意会员,并在标准模型中证明该方案是安全的。
Combined threshold signature algorithm with chameleon hash function, a new on-line/off-line threshold signature was proposed. Its security is based on discrete logarithm assumption. The scheme tolerates any tn/3 malicious players and can be proven secure in the standard model.
