密码学辅助教学系统的设计与实现

Design and Implementation of Cryptography Assisted Teaching System

针对目前密码学教学过程中存在的一些问题,设计并实现了一个密码学辅助教学系统.该系统可以依据用户输入的参数,将密码算法分步骤向用户动态展示算法执行过程中数据的变化情况,并利用Canvas软件以图形方式向用户动态展示密码算法的工作流程.与同类软件对比及并发性能测试结果表明,该系统不仅能帮助学生直观深入地理解抽象的密码算法原理及工作流程,还在结构、应用大小及实验数量上具有较好的竞争优势,在高并发环境下依旧能够保持优良的性能.

According to some existent issues in the current teaching of cryptography,a cryptography aided teaching system is designed and implemented.The system uses Canvas to dynamically display the workflow diagram and the inner data changes during the execution of the algorithm.The comparison with the similar software and the concurrent performance tests show that the cryptography assisted teaching system can not only help students understand the abstract cryptography algorithm principles and the intuitive workflow,but also have a competitive edge in structure,application size and the number of experiments;furthermore,it can still perform well in the high-concurrency environment.
