Enhance Fog-Based E-learning System Security Using Elliptic Curve Cryptography (ECC) and SQL Database

E-learning is recently days considered the easy media used to teach materials and courses. The E-learning environment contains a lot of resources and content related to each user profile. Those contents are considered private data or information for the user, so it is important to provide a secure environment for the users to keep their privacy safe. E-learning over fog computing takes place very fast, especially with the spread of (IoT) devices. Fog computing is offering a way to avoid latency and reduce the distance between the end users and resources over the cloud. This paper aimed to offer a secure method for the learning resources based on fog computing. Elliptic Curve Cryptography (ECC) algorithm is used to secure the data flow of the E-learning system over fog computing by using common and special key encryption in combination with AES. As the user data is encrypted and decrypted with the users’ keys to protect his privacy. The ECC is powerful encryption way and did not effects on the performance of the E-learning environment. At the end of the paper there is a comparison between RSA and ECC usage to illustrate the main difference between the two types of cryptography.
