基于RSA公钥体制的多重数字签名研究

Study of Multi Digital Signature Based on RSA Public Key System

针对多重数字签名认证问题，利用Ｌａｇｒａｎｇｅ插值多项式与ＲＳＡ数字签名方案相结合的方法，在ＲＳＡ公钥体制基础上提出了新型多重数字签名方案，并对其安全性进行了分析．依据初等数论知识证明了该方案的可行性，并具有真正意义上的密钥分散管理特性．

Aiming at the problem of multi digital signature authentication, this paper utilizes Lagrange -multinomial and RSA digital signature scheme to put forward a new multi -digital sig- nature scheme based on RSA public dy system, and analyses its security. This paper also proved the scheme's feasibility through the knowledge of primary math theory. The scheme has the genu- ine characteristic of private key dispersion management.
