An Application of the Technique of Encryption to Diskette Management
Xiao Suigui ( Department of Mathematics)
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.
