A Methodology for Secure Remote Deployment of Internet of Things Devices Based on Cryptographic Authentication

Abstract

The article is dedicated to the development of a methodological framework for secure remote deployment of Internet of Things devices based on cryptographic authentication. The relevance of the study is determined by the expansion of distributed IoT infrastructures, the growing dependence of industrial and service environments on remote device administration, and the rising exposure of connected endpoints to impersonation, firmware tampering, unauthorized enrollment, and trust-chain disruption. The scientific novelty lies in the integrated interpretation of remote deployment as a multi-phase cryptographic lifecycle rather than as an isolated provisioning event. The work describes the structural logic of identity provisioning, attestation-assisted trust establishment, secure channel creation, authenticated firmware distribution, and decentralized verification. Special attention is paid to hardware-backed onboarding, software-based attestation for constrained and legacy devices, segmented update delivery, and distributed trust validation. The work sets itself the goal of systematizing architectural and security principles that shape contemporary approaches to protected remote IoT deployment. To solve this task, comparative analysis, source synthesis, structural interpretation, and analytical generalization were used. The conclusion describes the transition toward lifecycle-oriented security models. The article will be useful for researchers, system architects, and engineers working with secure IoT infrastructures.
