Diseño e Implementación de un Módulo de Seguridad Hardware (HSM) Sobre Microcontrolador Basado en el Algoritmo HIGHT

Abstract

The circle of communication networks, in particular Internet, has opened new possibilities for the exchange of information. At the same time, there are increasing threats to the security of the information being transmitted. It is necessary to create different mechanisms, aimed at achieving a high confidentiality, authenticity and privacy in the handling of the information, for all that they have developed hardware security modules (HSM), also called cryptographic accelerators, which allow the safe administration of Cryptographic keys and fast cryptographic operations. In this project, a security module is designed to be implemented in microcontroller using the HIGHT encryption algorithm, a high security, low weight block encryption algorithm with blocks of 64 bits in length and 128 bits key, with a suitable implementation. Low cost, low power consumption and ultra-light. The execution of this project is oriented to the development of a free circulation tool, which meets the requirements of a cryptographic system with the limitations according to the device used. Consequently, this means an academic on the implementation of these little-known hardware keys in Colombia
