Improving Security Measures of E-Learning Database
E-learning is a platform that provides materials online with the objective of improving the users' teaching and learning experience. This paper is to provide security to users' passwords within the E-learning Password Management System (EPMS) in order to protect the database from hackers. The protection process is done by implementing a symmetric encryption algorithm named International Data Encryption Algorithm (IDEA) on the passwords. The algorithm will be improved by modifying the size of the same secret key that is used in both the encryption and decryption operations of the data.
