“…Network Time Synchronization (NTS) provides standardized cyber-trust assurance for e-learning systems by using three layers of trust criteria expanded to the public internet cyberspace together with an independent Network Time Synchronization source. The three layers of trust criteria are the basic factors that combine to granularly model what a legal user should be and are based on five trust characteristics targeted, subjective, measurable, dynamics, and conditionally passed [13]. Independent Network Time Synchronization source is used because in-built time synchronization modules and synchronization subnets based on network time protocol can be compromised which can threaten end-user and elearning platform private keys and digital signatures while also endangering the whole public key infrastructure used to secure the communication.…”

Learning has transposed the perception of teaching and learning considering knowledge delivery and knowledge acquirement. Today, e-learning participants access and upload their materials at any time and at any place since elearning technologies are typically hosted on the cloud. Cloud computing has embellished the base platform for the future of elearning, however, security and privacy remains a major concern. Cloud-hosted e-learning technologies as they are accessed over the internet suffer from the same risks to information security aspects namely availability, confidentiality, and integrity. In such a context, data authenticity, privacy, access rights and digital footprints are vulnerable in the cloud. Research in this domain focuses on specific components of cloud and elearning without covering a holistic view of applied cryptographic techniques and practical implementation. Hence, aiming at the various security aspects and impacts of cloud-based e-learning technologies, this paper puts forward reviewing the various cryptographic techniques used to secure data across the whole end-to-end cloud-based e-learning service spectrum using systematic review and exploratory method. The results obtained define several sets of criteria to evaluate the requirements of cryptographic techniques and propose an implementation framework across an end-to-end cloud-based e-learning architecture using multi-agent software.
