摘　　要：高校教务管理过程中,试卷以明文形式传输和集中存储,存在数据泄漏安全隐患。提出了一个基于数字证书的试卷防泄漏方案,采用AES算法加密试卷,试卷在数据库中以密文的形式存放,每个试卷文档的访问密钥随机产生,用RSA算法实现试卷访问密钥传递过程中的加解密操作。对试卷的上传、递交、下载模块进行了详细设计、编码实现和运行测试。实验结果表明,在试卷传输和集中存储过程中,试卷及其访问密钥均以密文形式存放,经过试卷上传、递交、下载环节,试卷文件的内容能够成功恢复。In the process of college teaching affair management, the exam papers is transmitted and stored in the form of plaintext, and there are hidden dangers of data leakage.A exam paper leakage prevention scheme is proposed, which uses the AES algorithm encryption papers, encrypts and stores the papers with random access key in the database, and employs RSA algorithm for encryption and decryption operations to transfer the access key of test paper.Three key modules （upload, submit and download） are designed, coded and tested.The experimental results show that, in the process of transmission and centralized storage, the exam paper and its access keys are stored in the form of cipher text, and the content of the exam paper can be successfully restored after the upload, submit and download procedure.
