Este paper presenta la tecnología Java Card y los certificados X.509 como método de autenticación en aplicaciones web en ambientes universitarios, en el caso concreto la Universidad Tecnológica de Panamá (UTP). La solución consiste en mejorar el escenario de acceso a los servicios de la UTP tratando de extender el uso de la Infraestructura de Clave Pública, llevando a cabo la integración de estas tecnologías que aporten mayor seguridad a todos los usuarios y que gocen de un acceso a los servicios ofrecidos de manera flexible, segura, garantizando la autenticidad, confidencialidad, integridad y no repudio.

We demonstrate generating complete and playable card games using evolutionary algorithms. Card games are represented in a previously devised card game description language, a context-free grammar. The syntax of this language allows us to use grammar-guided genetic programming. Candidate card games are evaluated through a cascading evaluation function, a multi-step process where games with undesired properties are progressively weeded out. Three representa- tive examples of generated games are analysed. We observed that these games are reasonably balanced and have skill ele- ments, they are not yet entertaining for human players. The particular shortcomings of the examples are discussed in re- gard to the generative process to be able to generate quality games

We present initial research regarding a system capable of generating novel card games. We furthermore propose a method for com- putationally analysing existing games of the same genre. Ultimately, we present a formalisation of card game rules, and a context-free grammar G cardgame capable of expressing the rules of a large variety of card games. Example derivations are given for the poker variant Texashold?em , Blackjack and UNO. Stochastic simulations are used both to verify the implementation of these well-known games, and to evaluate the results of new game rules derived from the grammar. In future work, this grammar will be used to evolve completely novel card games using a grammar- guided genetic program.
