Secure E-learning and Cryptography

This chapter investigates the problem of secure e-learning and the use cryptography algorithms as tools to ensure integrity, confidentiality, non-reputations, authentication, and access control to provide secure knowledge delivery, secure student feedback, and secure assessments. Providing privacy in e-learning focuses on the protection of personal information of a learner in an e-learning system, while secure e-learning focuses on complete, secure environments to provide integrity, confidentiality, authentication, authorization, and proof of origin. The secure e-learning system and the use of cryptography is the main theme of this chapter. In addition, the authors present a new cryptograph e-learning model based on PKI and cryptography access control. The model is based on creating secure shell system based on PKI, and each adding block has to certified itself to be assessable.
