Authentication techniques for a large-scale network are essential for the booming applications of e-commerce and e-business. In this thesis, authentication techniques for a larger-scale network are discussed. In-deep discussions on the independent path technique are presented. An authentication protocol based…

In the context of an object-oriented programming language such as Java, the ubiquitous use of instance fields and the presence of pointers (references to objects) make it difficult to understand a program's memory usage. Understanding memory usage is a key…

En este trabajo se presenta una técnica para verificar modularmente atomicidad de programas bytecode Java multi-thread. Los programas deben contar con una especificación referente a los bloqueos y al acceso a los recursos compartidos para realizar la verificación modular. Se…

El desarrollo de Sistemas Multi-agente es un problema complejo, su resolución generalmente involucra el análisis de problemas típicos de sistemas distribuidos, con entidades (agentes) que negocian, tienen la capacidad de aprendizaje, etc. Las soluciones existentes van desde desarrollos de cero…

Mobile agents are often described as a promising technology moving towards the vision of a widely distributed scalable electronic market. The deployment of electronic services, especially in the area of electronic commerce, raises essential questions closely related to security issues.…

Virtual method calls are a fundamental feature offered by Java, an object-oriented programming language. However, they are also a source of degradation of performance at run time and imprecision in interprocedural analyses. There are several well known, inexpensive analyses that…

Protecting sensitive information has become an important facet of software development.
One aspect of software security relies on information flow control (IFC), a technique for discovering information leaks in software. Despite the large body of work on language-based IFC, there…

Currently, the telecommunications management systems are powerful, however, maintain centralized and proprietary platforms, limiting this way, the growth of these telecommunications networks. This factor generates the need for scalable and open systems, stimulating the sectors of the telecommunications area to…

Programming embedded devices has been historically a difficult task, involving the learning of the features of a specific device such as the assembly language of a processor. This led to the use of Java in embedded system as a way…
