IMPLEMENTACIÓN DEL ALGORITMO DE CIFRADO TRIVIUM EN UN SISTEMA EMBEBIDO (AN IMPLEMENTATION OF THE TRIVIUM ENCRYPTION ALGORITHM IN AN EMBEDDED SYSTEM)
Resumen
En el presente trabajo se muestra la implementación de un sistema embebido capaz de cifrar datos a través del algoritmo TRIVIUM utilizando llaves creadas con criptografía de curvas elípticas. El sistema de cifrado fue implementado bajo el codiseño hardware-software donde las partes computacionalmente costosas fueron llevadas a módulos hardware y agregados a un sistema de cómputo tradicional CPU-RAM, donde un programa convencional se encarga de orquestar el trabajo. Los resultados obtenidos muestran que es posible mejorar el rendimiento de una aplicación al utilizar el codiseño hardware-software y además se pueden tener otros beneficios al utilizar tecnologías de implementación que integran todos los módulos del sistema en un único circuito integrado, como un bajo consumo de energía, características ideales para sistemas inalámbricos, móviles o portátiles.
The present work shows the implementation of an embedded system able to encrypt data using the TRIVIUM algorithm, with keys generated by means of elliptic curves. The system was designed using hardware-software codesing principles, where computationally expensive modules were implemented in hardware and added to a traditional computing system (CPU-RAM). A conventional program running on the computing system is responsible for orchestrating the work between hardware modules and the CPU. Obtained results show it is possible to improve an application performance by using hardware-software codesign. Additionally, several other benefits can be gained by integrating such solution in a system-on-a-chip such as low power consumption, ideal to wireless and portable systems.
