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.
