Prolog is a userful tool for geometry and graphics implementations because its primitives, such as unification, match the requiements of many geometric algorithms. During the last two years, we have implemented programs to solve several problems in Prolog, including a subset of the Graphical Kernel System, convex-hull calculation, planar graph traversal,(More)
Today network security, uptime and performance of network are important and serious issues in computer network. Anomaly is deviation from normal behavior affecting network security. Anomaly Extraction is identification of unusual flow from network, which is need of network operator. Anomaly extraction aims to automatically find the inconsistencies in large(More)
Session to session key variation is the only approach for achieving perfect security as per Shannon [1-2]. This paper deals with time variant key technique Automatic Variable Key (AVK) introduced by Bhunia[3-5] and we tried to analyze the performance of different types of new AVK techniques.
