摘　　要：近几年办公自动化系统使用程度愈来愈高,提高社会生产效率的同时也带来了更多的安全需求。很多数字签名系统应运而生。探讨了基于证书的数字签名系统的分析与设计,该系统通过VC编程实现。在填入个人相关信息后生成证书,其中公钥证书中包含有证书有效日期、RSA参数信息和签名值。私钥证书的相关RSA参数被私钥口令加密。签名系统通过散列运算得到文件摘要,然后再用私钥证书中的RSA参数信息对摘要进行签名运算,验证者随后可以用公钥证书的RSA参数信息对签名进行验证。In recent years,office automation increasingly becomes the main trend.The improvement of social production efficiency brings about at the same time more safety requirements,and many digital signature systems emerge right at the demand.This paper has discusses the design and implementation of RSA signature system based on the certificate,the system,through VC programming and filling in the personal information,produces the certificate,in which the public-key certificate contains in the certification valid date,RSA parameter information and signature values,while RSA parameters of the private-key certificate are encrypted by password.Signature system,through the hash operation,achieves the file Abstract,then with RSA parameter information in the private-key certificate,carries out signature operation on the Abstract.The verifier could authenticate the signature by RSA parameter information in public-key certificate.
