摘　　要：分析了考试系统的特点,然后在总结数据加密技术的基本原理和要求的基础上,着重研究了包括DES对称加密算法、RSA非对称加密算法、数字签名等诸多加密技术。针对远程考试系统数据安全性要求较高的特点,在系统设计和实现中采用了多层次的安全技术,如访问控制、数据加密、数字签名等。First,the paper analyzes some exam systems＂ characteristics and comprehension of large amount of references, then on the base of summarizing the basic theories and requirements of data encrypting techniques, it studies on several data enerypting techniques for network emphases, e.g. private-key encryption, public-key encryption, digital signature. Because the Internet exam system calls for higher safety, the safety technology with multi-levels is used in the exam design and implementation, such as visit control, data encryption, digital autograph and routine treatment, etc.
