摘　　要：分析了密码体制在数字档案管理应用中的作用,介绍了对称加密和非对称加密以及RSA加密算法和MD5算法的基本概念和工作原理,阐述了基于RSA及MD5的数字签名的实现过程,对其在数字档案管理中的签名及验证过程进行了分析与讨论.在相关文献提出的密钥集中式管理基础上,提出了一种较好的密钥集中式管理方法,该方法可克服密钥集中式管理中经常出现的瓶颈问题,对密钥进行有效的管理.First the password system in the numeral records management application vital role is ana- lyzed, and the symmetrical encryption and the asymmetrical encryption as well as the RSA encryption algorithm and the MD5 algorithm basic concept and the principle of work are introduced. Based on RSA and the MD5 digital signature realization process. The numeral records management signature and the confirmation process are analyzed and discussed in detail. This article to the key central management proposed in the literature has made the improvement. One good key central management is propased. This method may overcome the bottle neck question which in the key central management appears
