摘要
基于网络考试系统对数据安全性的要求,针对网络数据库的非法访问、攻击和恶意篡改进行了分析。利用身份认证技术、数字签名技术、访问控制技术和数据库加密技术等形成一套安全增强方案。该方案在一定程度上弥补了当前大多数考试系统在数据库安全方面的缺陷。
According to the demand of database security of network examination systems, this paper analyzed the unauthorized access, attacks and malicious tampering, designed a set of security enhancement which was based on identity certification, digital signing, access controlling, and database encryption. The security enhancement makes up the defects of the network database security in most examination systems at present.
