摘要
网络教学平台已成为各大高校广泛使用的网络教学手段,而网络考试系统作为教学效果的检验手段已成为必不可少的重要组成部分。根据网络考试的实际需要,运用密码学的方法提出高校网络考试安全机制,采用基于IBS的签名方案和CZK算法实现对教师和考生的身份鉴别,利用加密、数字签名等技术实现对试题下载及答卷安全上传,为网络考试构建一个安全的管理平台。
Network teaching platform has become a widely used teaching method widely used in universities,and the web examination system as a means of testing the teaching results has become an important part of the network teaching platform.Aiming at actual needs of network examination,a secure network examination in high school mechanism is proposed by using cryptological methods synthetically.Encryption,digital signature are used to authenticate the identity of teacher and examinee based on IBS signature and CZK algorithm,realizing security of downloading the examination paper for all examinees and submitting their papers.A secure management platform for examination is constructed.
