Abstract

The invention discloses a network teaching management system, which relates to the field of information security. The network teaching management system comprises a certificate authority (CA) center, a digital certificate module, a digital signature module and a digital rights management (DRM) module. A user acquires a corresponding digital certificate at the CA center by the digital certificate module, logs in the network teaching management system by the corresponding digital certificate, is authenticated by the digital certificate module, quits the network teaching management system if the user does not pass the authentication, performs a query operation and a browsing operation by the digital certificate module, realizes class selection and school record management by the digital signature module, and downloads teaching resources by the DRM module. The network teaching management system prevents own resources from being easily impacted, and ensures the availability, integrity and consistence of teaching management information.

Description

technical field [0001] The present invention relates to the field of information security, and the purpose is to utilize digital signature, digital certificate, CA (Certificate Authority, authority) authentication technology and DRM (Digital Rights Management, digital rights management) technology, in particular to a network teaching management system. Background technique [0002] With the rapid development of modern information technology, the rise and development of the information highway with computer network technology as the core, and the maturation of local area network technology, the teaching management system has entered the network era.
