Research on the Network Security Strategy for Digital Distance Education Platform

Distance education has been an important development tendency and learning platform with the emphasis of lifelong learning of the society. Networked learning and teaching is a main characteristic of distance education, which inevitably needs to transmit large magnitude of private data among students, teachers and the education platform. To protect the security of data transmission and storage, a networked security strategy was proposed. The security strategy is based on the technologies of intrusion detection and digital signature. An intrusion detection model was established in accordance to the main tasks of distance education platform. The encryption process of digital signature was illustrated along with the information flow of the distance education platform. The paper offers an effective reference for solving security problems of distance education platforms
