| 摘 要： | 数据库系统中的授权认证和密钥管理机制是实现数据库安全共享的核心问题。本文利用现代密码学中的数字签名技术,提出了一种新的数据库授权访问控制和密钥管理方法,构建了安全的数据库授权共享机制。公钥密码的高度安全性充分保证了用户身份的不可伪装性和数据库密钥的高度秘密性,实现了数据库的共享性与安全性的有机结合与统一。

| Abstract: | The mechanism of authorized authentication and key management in database system is the kernel problem in the achievement of database secure sharing.Based on modern cryptographic technology:digital signature,this thesis proposes a new method for the authorized access control and key management of database. A secure mechanism of the authorized sharing is constructed.The propreties of sharing and secrecy of database are combined reasonably since the non-personating of user identity and the high secrecy of database key can be assured by the high security of public key cryptosystem. |
