几种数字签名方案的密码学研究

A Cryptographic Study of Some Digital Signature Schemes

Manoj Kumar

摘要:

在这篇论文中,我们提出了一些有向签名方案。此外,我们还讨论了它们在不同情况下的应用。在这篇论文中,我们将讨论所提出的有向数字签名方案在设计过程中的安全性问题。在实际应用中广泛使用的大多数数字签名方案的安全性都是基于两个难题,即整数的因式分解问题(RSA方案)和有限域上离散元的求取问题(ElGamal方案)。本论文拟开展的工作共分为七章。

英文摘要:

In this thesis, we propose some directed signature schemes. In addition, we have discussed their applications in different situations. In this thesis, we would like to discuss the security aspects during the design process of the proposed directed digital signature schemes. The security of the most digital signature schemes widely use in practice is based on the two difficult problems, viz; the problem of factoring integers (The RSA scheme) and the problem of finding discrete logarithms over finite fields (The ElGamal scheme). The proposed works in this thesis is divided into seven chapters.
