加密技术在磁盘管理上的应用

在计算机程序设计教学活动中,上机是一项很重要的内容,为了掌握了解学生学习和完成上机练习的情况,常常要检查学生的磁盘,由于在正常情况下,磁盘程序拷贝简单容易,学生的上机练习甚至考试内容互相拷贝的现象时有发生。所以,检查的结果反应不了学生的实际水平,给评定学生学习成绩带来困难。本文针对这一实际问题,提出了一种简单易行有效的磁盘加密措施,并把它用于学生磁盘管理,使问题得到园满解决,收到了很好的效果。本文所介绍的方法,对其它学校的学生磁盘管理也很有参考价值。

An Application of the Technique of Encryption to Diskette Management

Of the proceeding of computer propramming, teaching practice is very important.To know how the students have learnt and completed their operation practices we usually check their diskettes. Because diskette programmes are easily copied under normal conditions, it often happens that students would copy their practices and even test answers from one another. As a result, the check can hardly reflect the real levels of their learnins and the teacher will not bc able to give them grades accurately. In order to solve this problem , here a simple and practicable method of diskette encryption is suggested which can be applied to the management of the students diskettes. By using this method we have effectively prevented the students from copying practices or answers each other.
