Cidades Inteligentes & Big Data

Tecnologias de Big Data como habilitadoras das Cidades do Futuro - Uma abordagem top-down

Abstract: This work aims to discuss the themes of smart cities and big data, inserted within the same context, and to show the numerous points at which they interrelate. It is discussed how big data technologies are a fundamental enabler so that smart cities can actually be implemented. Both concepts are formally introduced, with the concept of smart cities discussed being inserted within the architecture and technological map of the big data value chain. Finally, a practical example of implementing a... read more

Tecnologias SDN e NFV; e SDN como habilitadora de NFV

Abstract: In recent years, the expansion of internet access has led to a true revolution in telecommunications. However, the very nature of the architecture of the internet has shown itself to be a bottleneck that prevents innovations in the medium. Thus, increases in operating capital expenditures, as well as increased network complexity are inevitable. In order to solve part of these problems, new technologies, SDN and NFV, appear. Although both are conceptually independent of each other, the set of common goals, as well as the possibility of adopting both together,... read more

Introdução aos protocolos CL-AKA

Abstract: The use of digital certificates distributed by a Public Key Infrastructure (PKI) is the most widespread methodology in symmetric key agreement protocols. In this work, some alternative methodologies will be discussed, with a greater focus on CL-AKA protocols, ie, authenticated key agreement protocols without the use of certificates. The theoretical foundations, two protocol implementations, and some practical applications and proposals will be discussed.

Resumo: A utilização de certificados digitais distribuídos por uma Infraestrutura de chaves públicas (PKI) é a metodologia mais difundida em protocolos de acordo de chave simétrica. Neste trabalho serão discutidas algumas metodologias alternativas,... read more

Revisão envolvendo a viabilidade da utilização de NFV em conjunto com SDN sobre servidores ARM de nova geração

Abstract: This work reviews the feasibility of using NFV (Network Function Virtualization) and SDN (Software Defined Networks) technologies together on an ARM hardware platform. A theoretical introduction is made on the subject, a brief exposition of the architecture of NFV and SDN technologies, as well as a study of motivations, requirements and challenges, with a main focus on NFV. SDN here is mainly seen as a possibility that the use of these technologies together can more easily lead to the fulfillment of... read more
