基于B/S结构的数据库四层安全体系结构研究

Research of Four-layer Security Database Architecture Based on B/S Mode

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,提出了一种新的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,描述了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 as for the defects or security problems in traditional three-layer architecture,and defines the function of each layer and the workflow of four-layer security architecture. Using a private key as digital signature, a public key encryption and intermediate-level encryption is to enhance system security.
