分析了两个基于RSA的密码协议的安全性,一个是张韦王提出的基于RSA的多重数字签名方案,另一个是费王提出的基于RSA防欺诈的门限秘密共享体制。发现了这两个方案安全的弱点,指出了可能存在的欺骗。
The security of two RSA-based cryptographic protocols is analyzed. One is the RSA-based multiple digital signature scheme proposed by Zhang Weiwang and the other is the threshold-based secret sharing scheme based on RSA anti-cheat proposed by Fei Wang. Found the weaknesses of these two programs and pointed out the possible deception.
