铸造高校网络考试的公平之盾——综合防舞弊网络考试系统设计与实现

Founding a Justice-Shield for Network Examination in University——Design and Implementation of a Comprehensive Anti-Cheating Network Examination System

文章在分析考试舞弊原因、网络考试实施过程四要素的基础上，对ISO安全服务模型进行扩展，提出包括身份认证、试题访问控制、加密试题信息、数据防篡改、保护考试通道、防作弊组卷和限制考生端行为等7项防范措施的综合防舞弊技术机制，并阐述远程命令技术、数据库端加密技术等关键问题。实践表明，综合防舞弊网络考试系统具有良好的防舞弊性能。

Since a single anti-cheating technique can not be fully effective, the researchers develop a Comprehensive Anti-Cheating Network Examination System (CACNES) to cope with the challenges from a variety of cheating on examination. First, the cause of cheating on examination and the four elements of network examination's implementation process are analyzed in this paper. Then, a Comprehensive Anti-Cheating Technique Mechanism that extended from the ISO Security Services Model is brought forward. It includes seven precautions, such as authentication, test questions access control, encryption for test information, data anti-tampering, protection of examination channels, and limit of the candidate's side behaviors, etc. Last, some key issues are elaborated, including remote command technology, database-side encryption technology, etc. Practice shows that the CACNES has a good anti-cheating performance.
