Based On The E-Learning Multicast Distance Teaching Safety Analysis And Research Solutions

With the development of network technique and self-learning tendency in 21 centuries, education is no longer confined in the traditional classroom teaching. Interactive network teaching has already become a reality. The network teaching system carried out a modern teaching instruction that takes students instead of teachers as center. The interactive network teaching system is advantageous to train student to study independently and work together with other members, in which approach the education reforms in china would be promoted.E-Learning remote education based on net of network is a need of the social development,and it has wide prospect and market. The educators of all universities and colleges must attach importance to this market. E-Learning remote education based on multicast is also a important way to realize modern remote education, which has many advantages absented from some unicast and broadcasting system. However, the problem of security should be noticed as people are enjoying the new technology too. Therefore, when building the system of E-Learning remote education based on multicast, many problems, i.e.the security of multicast or the security of intellectual property rights should become the prior problem.This article analyzes the various problems of E-Learning remote education based on multicast and provides the relevant model of remote education, Through the use of smart cards landing, group key management, digital fingerprint technology, source authentication techniques, such as technology solutions, including learning content tapped, teaching resources for copyright protection, a group open to receive the data sent to the wrong data, and other related security issues.The author's main work includes the following contents:1,Introduce the knowledge of E-Learning remote education, multicast and related knowledge, and analyze the problem of security in E-Learning remote education and multicast2,Particularly analyze the security problem of E-Learning remote education based on multicast and mention the relevant resorting project.3,Design a series of E-Learning remote education system, which can basically realize varieties of functions in E-Learning remote education.4,Integrate the security problems of E-Learning remote education based on multicast and put forward a security problem management model of E-Learning remote education based on multicast...
