    Framework para la caracterización de aplicaciones Big Data en un proveedor de computación en la nube
    (Universidad de San Buenaventura - Cali, 2018) Reyes García, Yorley; Cárdenas Martínez, Jair Gustavo; Barraza Alvarado, Fernando
    This document presents a framework proposal for the implementation of a Big Data solution using a Cloud Computing model. The framework, of conceptual type, allows to guide the implementation of a Big Data solution by means of the revision of concepts through a tool, following a logical workflow of these. It includes the explanation of the tool developed, its configuration and how to use it. At the end, the guidelines to be followed for the conclusion of the work are presented.

    Implementar un Sistema de información integrado con las tecnologías de la información para agilizar los procesos de check in y check out en la cadena de Hoteles Estelar
    (2021) Mejia Jiménez, Luisa Fernanda; Henao Hoyos, Juan Pablo
    The world we perceive today moves around technological advances that have allowed a global connection with multiple purposes in a universal network of tools that have different functions in the personal and professional life of an individual. These same connections have motivated millions of people around the world to travel to get a closer look at the landscapes, socio-cultural behaviours, attractions and resources of an unusual and distant territory. Likewise, daily trips have become vital in the exchange of resources or in the development of negotiations between different companies or organizations. The added value of the tourist sector in the city of Medellín is imperious in comparison with other cities in Colombia due to the dynamics that are developed there, so that multiple tourists arrive every day to carry out different activities. In addition, this city has been able to consolidate as a center of innovation and intelligent destination monopolizing the glances of national and international travelers. In this order of ideas, we seek to implement an information system integrated with information technologies (software / hardware) in the chain of Hoteles Estelar, where customers can make the processes of self check-in and check-out, with greater agility and efficiency

    Sistema criptográfico para almacenamiento y transporte de información basado en álgebra de curvas hiperelípticas
    (2016-12-12) Cortés Osorio, Carlos Eduardo; Casas García, Oscar; Trujillo Olaya, Vladimir
    This work presents the implementation of a cryptographic system that uses a hypereleptic curve of genus 2 working in a finite field GF [q]; Where q is a prime number of 192 bits, uses the Cantor algorithm for addition and doubling of divisors and the Montgomery ladder Multiplication method to perform the computation of an integer by a divisor, all this in order to perform the algorithm Diffie-Hellman key exchange version for hypereliptic curves (DHHEC). The system also uses a 128-bit block cipher called TWOFISH for encryption and decryption of information. The key to this algorithm results from selecting the least significant 128 bits of the 192-bit agreed-upon key.
