dc.description.abstractEn los últimos años se han estudiado ampliamente arquitecturas de encriptamiento digitales, pero la tendencia a mejorar la velocidad y capacidad de procesamiento ha mostrado que la tecnología digital tiene límites que sólo pueden ser superados por tecnologías analógicas La clonación de cuadros, insignias, símbolos, cuentas de dinero o patrones, es una práctica mundial que deja incalculables pérdidas económicas a entidades estatales y privadas; combatir esta práctica es un problema serio para muchos bancos, negocios, y consumidores. Los grandes avances en hardware y software para procesar imágenes, y la cada vez mejorada resolución y capacidad de los nuevos dispositivos de entrada y salida de datos (pe.: CCD, scaners, impresoras) de una computadora ha permitido que sea un problema simple reproducir cuadros, insignias, símbolos, cuentas de dinero o patrones. Otra área de aplicación de la criptografía, son las redes mundiales como Internet y las redes telefónicas, a través de ellas se manejan grandes volúmenes de información confidencial: de tarjetas de crédito, de transacciones bancarias, corporativa y/o gubernamental, etc. Lista información se expone continuamente Ios ataques d© tes cada vez más hábiles programadores llamados "hackers”. La alta velocidad de encriptamiento y direccionamiento de datos es ocio aspecto a tener en cuenta, en la medida que las técnicas criptográficas son aplicadas a dispositivos con menores capacidades de cómputo, por ejemplo los dispositivos de comunicaciones móviles, a través de los cuales también se maneja información confidencial.spa
dc.description.abstractenglishIn recent years, digital encryption architectures have been widely studied, but the trend towards improving speed and processing capacity has shown that digital technology has limits that can only be overcome by analog technologies. Cloning pictures, badges, symbols, money bills or patterns is a worldwide practice that causes incalculable economic losses to state and private entities; combating this practice is a serious problem for many banks, businesses, and consumers. The great advances in hardware and software for processing images, and the ever-improving resolution and capacity of new input and output devices (e.g. CCDs, scanners, printers) of a computer have made it a simple problem to reproduce pictures, badges, symbols, money bills or patterns. Another area of ​​application of cryptography is global networks such as the Internet and telephone networks, through which large volumes of confidential information are handled: credit cards, bank transactions, corporate and/or government, etc. This information is continually exposed to attacks by increasingly skilled programmers known as "hackers." The high speed of encryption and data routing is another aspect to take into account, as cryptographic techniques are applied to devices with lower computing capacities, for example mobile communication devices, through which confidential information is also handled.spa
