基于启发式教学方法深入掌握文件的保密传输过程

Mastering Information Secure Transmission Based on Heuristic Teaching

文件保密传输是网络信息安全课程的重要内容。文件保密传输涉及到对称加密、非对称加密、数字签名、数字摘要等重要但难以理解的概念,本文结合启发式教学方式的理念讲述了一个文件保密传输体系的基本环节和流程。首先引导学生思考保密传输需要考虑的安全性问题,其次启发学生回顾跟安全性相关的重要概念,最后结合案例分析文件保密传输过程的安全体系。通过三步启发式教学方法,有效解决了学生难以理解抽象概念,较好提升了教学效果。

The information secure transmission is important for the course of network information security.It refers to some important concepts,such as Symmetric encryption,asymmetric encryption,digital signature,and digital digest while it is difficult to understand.Heuristic education is an effective way to explain the process of information secure transmission.Firstly,guide students to consider the problem of safety in information secure transmission.Secondly,enlighten students to recall the important concepts related with security.Finally,use examples to analysis the security system of information secure transmission.It is effective to solve the situation that students have difficulty to understand the abstract concepts.
