摘要
针对传统B/S结构的数据库三层体系结构的安全性上存在的问题和不足,提出一种新的B/S结构的数据库四层安全体系结构,并对各层功能进行了定义,描述四层安全系统的工作流程,通过在客户端用私钥数字签名,公钥加密和中间层加密等手段来增强系统的安全性.
This paper proposes a new four-layer security database architecture based on B/S mode, in view of the insufficient on security problems in traditional three-layer architecture, and defines the function of each layer and the workilow of four-layer security architecture.By the use of a private key as digital signature, a public key encryption and intermediate-level encryption, system security is enhanced.
