【摘要】 随着计算机技术的飞速发展,利用 Internet/Intranet 开展网上教学,已成为现代教育技术应用的一种新模式。本文在广泛调研和查阅大量文献的基础上,系统分析了教育体制、教学模式以及网络教学的现状,对开发网络课程的理论基础、设计原则、构成要素、多媒体制作技术以及网络课程运行环境等方面进行了深入地研究;并根据网络安全的需要,对系统进行安全性分析与设计。本系统的特色是把软件工程的思想贯穿整个开发过程,同时采用了数据加密、公钥密码系统、认证和数字签名等网络安全技术,以此来保证系统的安全运行。更多还原

【Abstract】 With the development of the computer,taking advantage of Interuet/Intranet to open interuet education has become a new model of the application in the modern education technology.Based on widespread researching and consulting a number of books,this paper systematically analyzes the research status of education system,modern type of instruction and network teaching.This paper makes an intensive study of theoretical,design principle,construction,multimedia making technology and running ambient of network.Moreover,according to network security needs,the system has been safety analyzed and designed. The advantage of system is the application of software engineering thinking in entire lifecycle,and use the network security technology of data encryption,public-key cryptosystem,certification and digital signature in order to running correctly.更多还原
