Abstract:

Based on strong RSA assumption and the forking lemma, two proxy multi-signature schemes are presented, one is blind proxy multi-signature scheme and the other is proxy multi-signature scheme based on self-certified cryptosystem. Their correction and security are verified. The first scheme partly refers the affine transform and avoids the attacking way in some documents. The second scheme is based on self-certified cryptosystem which takes the advantage of PKI and identity-based cryptosystem.

Key words: proxy signature, proxy multi-signature, blind signature, strong RSA assumption, self-certified cryptosystem

摘要：

基于强RSA假定和分叉引理提出2种代理签名方案：盲代理多重签名方案和基于自认证密码系统的代理多重签名方案，证明它们的安全性。前一种方案设计时部分采用二元仿射变换，可以抵抗一些常见的攻击，后一种方案基于兼有公钥证书密码系统和身份密码系统优点的自认证密码系统。
