“…It encompasses provisioning and de-provisioning identities, identity authentication, and authorization to a user to access services. In a nutshell, the main goal of identity and access management is to ensure that only authenticated users have access to specific services [40]. Figure 3 helps to give a complete overview of the identity and access management topics that we will address in this survey.…”

The Internet of Things (IoT) encompasses a large number of connected devices, generating and sharing diﬀerent types of data among themselves. These data enable the creation of society-changing applications, such as health monitoring and autonomous vehicles. Under this context, protecting the access of these connected devices and their data is critical to IoT applications’ success, since a single data breach can incur into a cascade eﬀect, which leads to devastating consequences. Identity and Access Management (IAM) systems provide mechanisms to identify individuals at the network and determine their access privileges, thus avoiding inappropriate access. However, the current IAMs system struggles to provide the scale or manage the complex relationships that IoT brings. In this work, we present a comprehensive state-of-the-art survey of IAMs and the main concepts and challenges when applied to IoT. First, we overview the IoT technology, giving its essential characteristics and communication architectures and its main applications. Then, we present IAMs state-of-the-art and the main concepts, existing architectures, and challenges. Finally, we focus on current IAMs that aims to tackle the IoT complexity, along with an in-depth analysis of their proposals and future directions in the ﬁeld.

“…Along with this development, there is a continuously increasing need for reliable online identity authentication [15]. Identity management systems (IMSs) are designed to help manage users identities across multiple systems and services by providing authentication, together with identification and authorization [16], [17]. Two larger classes of IMSs exist that are either centralized or decentralized.…”

Decentralized identity management systems (IMSs) are envisaged to decrease fraud, enhance users' privacy and introduce transparency to the rather opaque business with personal data. Given these quite desirable features it is not surprising that many whitepapers discuss the technical feasibility of decentralized IMSs. What is missing, however, is the consideration of actual user requirements and their assessment of the decentralized IMS's ability to actually protect their privacy. We provide insights on the perceived usability of decentralized IMS features as well as on user concerns and requirements. The result of this study is a trigger for further and iterative usability testing that takes up the insights provided by this study. The result suggests that the usability of decentralized IMSs is not as straightforward as presumed by many companies and that a good deal of work is necessary to identify and implement actual user requirements into a functioning prototype.

Burnable Pseudo-Identity: A Non-Binding Anonymous Identity Method for Ethereum

et al. 2021

The concept of identity has become one common research topic in security and privacy where the real identity of users must be preserved, usually covered by pseudonym identifiers. With the rise of Blockchain-based systems, identities are becoming even more critical than before, mainly due to the immutability property. In fact, many publicly accessible Blockchain networks like Ethereum rely on pseudonymization as a method for identifying subject actions. Pseudonyms are often employed to maintain anonymity, but true anonymity requires unlinkability. Without this property, any attacker can examine the messages sent by a specific pseudonym and learn new information about the holder of this pseudonym. This use of Blockchain collides with regulations because of the right to be forgotten, and Blockchainbased solutions are ensuring that every data stored within the chain will not be modified. In this paper we define a method and a tool for dealing with digital identities within Blockchain environments that are compliant with regulations. The proposed method provides a way to grant digital pseudo identities unlinked to the real identity. This new method uses the benefits of key derivation systems to ensure a non-binding interaction between users and the information model associated with their identity. The proposed method is demonstated in the Ethereum context and illustrated with a case study.
