In this article we present a performance comparison of four symmetric block ciphers namely DES, Triple-DES, AES, and Blowfish. Performance evaluation based on CPU execution time is conducted under WinXP and Ubuntu /Linux version 8.10 operating system platforms. The study…

Presentaciones del curso "Internet Programming with Java" impartido en la Université M'Hamed Bougara (Bourmerdes, Argelia) en abril de 2007., Proyecto financiado por la Unión Europea: TEMPUS JEP-32102-2004, Licence Professionnelle Technologies des Applications Web (Professional License for Web Application Technologies).

In this note, I propose two extensions to the Java virtual machine (or VM) to allow dynamic languages such as Dylan, Scheme and Smalltalk to be efficiently implemented on the VM. These extensions do not affect the performance of pure…

This paper presents a laboratory session of an advanced programming course to introduce students to the technology involved with the Java programming language. In this special lab session the educational software tool VisualJVM is used, providing a graphical front-end to…

This paper introduces a new set of compact interactive simulations developed for the constructive learning of computer networks concepts. These simulations, which compose a virtual laboratory implemented as portable Java applets, have been created by combining EJS (Easy Java Simulations)…

Microsoft's .NET Framework, and JAVA platforms, are based in a just-in-time compilation philosophy. Software developed using these technologies is executed in a hardware independent framework, which provides a full object-oriented
environment, and in some cases allows the interaction
of several…

LOCAL VARIABLES ARE FUNDAMENTAL TO DESCRIBE AND IMPLEMENT COMPUTER ALGORITHMS AND TO SPECIFY SOME OF THEIR PROPERTIES SUCH AS CORRECTNESS, TERMINATION AND PERFORMANCE. IN THIS PAPER, WE ADDRESS THE RUN-TIME ASSERTION CHECKING PROBLEM INVOLVING LOCAL VARIABLES IN JAVA PROGRAMS USING…

Web-based learning environments are becoming increasingly popular in higher education. One of the most important web-learning resources is the virtual laboratory (VL), which gives students an easy way for training and learning through the Internet. Moreover, on-line collaborative communication represents…
