There can be two vital criteria of selecting an algorithm to fulfil one’s encryption requirement. The security level of the cipher (secrecy) and the encryption time (performance). There is less focus on secrecy of ciphers as a security measurement, thus…

First this paper points out two common problems of utilizing processors under multicore architecture, namely processors waiting for IO operation to finish and load balancing among cores. Then it makes an analysis of the reasons for them. In order to…

With the emergence and evolution of computer hardware, software and networks - virtual classrooms now exist which enable teachers and students to experience learning activities and to work together at a distance either directly or on a part-time basis. We…

This work provides an imperial solution to the problems faced by man while enduring hazardous tasks like handling and disposal of nuclear wastes, monitoring nuclear power plants, mining operations etc .which have to be aborted if expertise group running it…

This study aims to obtain the digital image encryption algorithm with a simple but secure process, fast and efficient computing resources. The algorithms developed in this study were super-encryption algorithm that combines two of cipher called Playfair cipher and the…
