Tangible security: Survey of methods supporting secure ad-hoc connects of edge devices with physical context

Abstract

Edge computing is the concept of moving computation back to the endpoints of a network, as an alternative to, or in combination with, centralized, cloud-based architectures. It is especially of interest for Internet-of-Things and Cyber-Physical Systems where embedded endpoints make up the edge of the network, and where these devices need to make localised, time-critical decisions. In these environment secure, ad-hoc device-to-device interaction is important, but offers a challenge because devices might belong to different systems, or security domains, which complicates trusted communication and key establishment. There has been a growing interest in complementing conventional cryptography with physical context. This allows for services that are difficult to achieve with existing cryptographic mechanisms: devices pairing (initial key establishment) and proof-of-proximity (ensuring devices are physically present). Numerous methods, the majority of which are based on the physical context of device characteristics, behavior or environment, have been proposed to supplement cryptography in achieving these services. This paper provides an overview of this area of research, first discussing the nature and importance of the two specified security services in ad-hoc communication settings and then providing an introduction to prominent physical context security approaches in literature.

Security and Privacy in the Industrial Internet of Things: Current Standards and Future Challenges

“…This is summarised in Table III. The use of similar or exact technologies to guarantee security services for edge devices [52] and connectivity security aid in highlighting connectivity security as an extension of edge device security and supports the need to guarantee strong edge device security from the inception of an IIoT network. The extension of these implementing technologies also allows for load sharing of the security requirements between the two network areas while building in redundancies that could serve as backup protections in the event of a security breach.…”

Short-Range Audio Channels Security: Survey of Mechanisms, Applications, and Research Challenges

“…As highlighted in Tab. I, some security solutions based on audio channels have been quickly touched in the recent literature by few surveys, focusing either on context-based security [8], [9], authentication solutions [10], side-channel attacks [11], CAPTCHAs [12] or forensic applications [13]. However, to the best of our knowledge, our contribution is the first to specifically survey, classify, and systematize security methods, applications, and use-cases using only short-range audio channels, as well as to evaluate such strategies across different use-cases and objectives, and to propose further research challenges-specific to this domain.…”

Smart Microgrid Energy Market: Evaluating Distributed Ledger Technologies for Remote and Constrained Microgrid Deployments

“…These devices also operate in mission critical environments with high availability requirements. Reliability, security, privacy and low latency are prioritised for large data exchange communications [28][29][30][31][32][33]. An investigation is thus required into the impact that the processor-intensive DLT operations could have on device operations.…”
