Uso de Blockchain para Privacidade e Segurança em Internet das Coisas

Abstract

The Brazilian Symposium on Information and Computational Systems Security (SBSeg) is a scientific event promoted annually by the Brazilian Computer Society (SBC). SBSeg represents the country’s main forum for disseminating research results and relevant activities related to information and computational systems security. In this edition (2017), 20 short-course proposals were submitted, a significant number that demonstrates the relevance and the community interest in current subjects of the area. Four proposals were selected for publication and presentation, an acceptance rate of 20%. This book comprises the four chapters produced by the authors of the accepted short-course proposals. Chapter 1 is in line with the growing and inevitable trend of using small computing devices. This chapter discusses contemporary issues in the area of ​​security and privacy in the context of ubiquitous computing, as well as pointing out research problems that have not yet been solved. Chapter 2 introduces key hardware-based security technologies, covering functionality and use cases of the Intel Software Guard Extensions (SGX) architecture. Chapters 3 and 4 discuss blockchain technology, a diffusion-based technology that has driven new research, development, and innovation in the area of ​​computational systems security. Chapter 3 presents the technology fundamentals and programming aspects involved in application development and systems security. Chapter 4 presents how blockchain technology can be used to provide security and privacy in the context of the Internet of Things (IoT).
