Implementation of ?HIGHT? encryption algorithm on microcontroller

Nowadays, the trend of cryptography has focused on designing algorithms with specific features for the growing demand for privacy and security in portable communication systems with limited memory and power resources, these types of algorithms "light weight" are characterized by high performance, low cost and low power consumption which allows them to be implemented in ultralight applications and embedded systems as in the case of the algorithm HIGHT. The HIGHT is a lightweight block cipher, with block length of 64 bits and key length of 128 bits based on simple X-OR logic operations, addition in modular arithmetic 28 and circular shift bit, what characterizes this algorithm to be oriented in hardware. In this paper, the study, development and implementation of HIGHT encryption algorithm in hardware is presented.
