Implementation of a Secured Student Record Management using Modified RC6 and OTP Algorithms

Abstract

In today's generation, the utilization of multimedia for communication plays an important role in transmitting authentic messages over the network. However. its growth has also made easy distribution and duplication. Educational Institutions have salient academic documents which are official and highly confidential and institutions are intended to uphold their safety. This is achieved through FERPA or Family Educational Rights and Privacy Act which is one of the strongest privacy protection laws in the U.S while locally, the Philippines and its universities need to achieve their commitment to comply with the Data Privacy Act of 2012. The emerging increased use of applications such as Student Information System (SIS) and Learning Management Systems (LMS), consequently raised security concerns ensuring its confidentiality, integrity, and availability. It was based on the avalanche effect, correlation coefficient, mean squared error, and the speed measurement of encryption and decryption processes that the statistical and runtime execution analysis were conducted. The quality of encryption was improved as evidenced by the 54.69% avalanche effect, which surpasses the standard of 50%, a very low average correlation coefficient of 0.0022 for the horizontal, vertical and diagonal directions, and a high mean squared error (MSE) of 11,556. Minimal runtime was also achieved based on the encryption runtime average of 0.98 and decryption runtime average of 1.93. Based on the numerical and visual results of the actual runtime and automatic tests, the good qualities of encryption and authentication were achieved.
