Incorporating Blockchain into Role Engineering: A Reference Architecture Using ISO/IEC/IEEE 42010 Notation

Abstract

Blockchain technology is taking the world by storm. With its transparent, secure and decentralized nature, it has emerged as a disruptive technology for numerous industrial applications. One of them is Role Engineering: the Role-based Security (RBS), which is a requirement of all organizations and its secure and efficient enforcement, reduces the risk of entities having unauthorized access privileges. This paper presents a review on Role Engineering to provide general readers with its overview, including an early theoretical paper which leads to standard, background knowledge, and motivation. The paper expands on the role of Blockchain in role-based security by presenting the challenges in traditional models and their potential solutions by Blockchain incorporation. Finally, integrated reference architecture of Blockchain and Role-based Security is presented which used the ISO/IEC/IEEE 42010 guidelines and Notation.
