摘 要
虽然数字签名方案种类繁多，可解决的问题也很广泛，但是提出理论上可行的数字签名方案需要满足安全性、高效性。大多数数字签名仅仅作了理论上的分析，并未进行安全性证明，导致提出的方案存在或多或少的安全性缺陷，而执行效率高低是评价该方案优劣的重要指标，因此随着无证书密码体制的发展，设计相应的无证书数字签名方案成为了数字签名领域的热点研究方向之一。
基于身份的密码体制，公钥就是用户的生物特征，由于生物特征具有唯一性，近年来，基于生物特征的数字方案得到了大量的研究。现在研究的密码体制在电子计算机时代是安全的
本文主要分析了基于RSA的数字签名系统的一些基本功能和组成情况，包括系统的需求分析、系统结构，功能模块划分以及数据库模式分析等，重点对应用程序的实际开发实现作了介绍。达到了数据的一致性和安全性，且应用程序功能完备，符合了RSA算法加密和解密较系统作为典型的信息管理系统(MIS)的要求。同时简单介绍了java编程环境和MYSQL数据库管理系统的功能特点。

ABSTRACT
Although there are many kinds of digital signature schemes that can solve many problems, a feasible signature scheme is required to meet the requirements of security and efficiency. Most digital signatures only made a theoretical analysis, did not carry out security proof, the proposed scheme leads to defects more or less secure, and efficiency is an important index to evaluate the scheme, so with the development of clpkc, certificateless digital signature scheme design corresponding has become one of hot research the direction of the field of digital signature.
Identity based cryptosystem, public key is user’s biometrics. Because biometrics is unique, biometrics based digital schemes have been extensively studied in recent years. The cryptosystems that are now studied are safe in the era of electronic computers
This paper mainly analyzes the basic functions and composition of the digital signature system based on RSA, including the requirement analysis, system structure, function module partition and database schema analysis, etc., and focuses on the actual development and implementation of the application program. It achieves the consistency and security of data, and the application function is complete, which accords with the requirement of RSA algorithm encryption and decryption as a typical information management system (MIS). At the same time, the features of the Java programming environment and the MYSQL database management system are briefly introduced.
