Research ArticleOpen accessIn the abstractMDS Algorithm for EncryptionMani Arora, Derick Engles, Sandeep SharmaMost of the encryption algorithms used today generates huge cipher messages as well as long encryption keys. These approaches require time and are computationally intensive .While sending data packets through the network a compression technique along with cryptography can be applied to reduce the data packet size for better bandwidth utilization and hence faster transmission of data. In this study … …Journal of Computer Science, Vol. 11, Issue 3 · 3 Apr 2015 · 7,295 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Framework for a Multi-Layered Security of an Automated Programming Code Assessment ToolMohd Fadzli Marhusin, Muhammad Firdaus Zul Kafli, Rossilawati Sulaiman et al.In a learning environment, a low student-lecturer ratio is considered a practical solution by many educational institutions. However, the number of students in information technology is increasing every year. This could lead to a significant increase in the workload of lecturers, who need to evaluate assignments, quizzes and projects. Hence, it is desirable that an automated assessment tool is used … …Journal of Computer Science, Vol. 11, Issue 2 · 18 Sep 2014 · 6,630 accessesView PDF Cite
