POST-QUANTUM IDENTITY MESH FOR AUTONOMOUS 5G, IOT, AND NATIONAL CONNECTIVITY SYSTEMS: IMPLICATIONS FOR FUTURE-RESILIENT DIGITAL INFRASTRUCTURE
Main Article Content
Abstract
Next-generation communication technologies such as fifth-generation (5G) wireless telecommunications systems enable the expansion of digital connectivity across commercial, industrial, and national infrastructure; as a result, an explosive increase in the use of the Internet of Things (IoT). In these highly distributed, autonomous environments, secure, scalable, and interoperable identity management systems are needed to provide authentication, authorization, and access control (AAA) for billions of devices and users. Centralized identity management frameworks have critical vulnerabilities due to their reliance on centralized architectures and traditional cryptographic algorithms. Vulnerabilities include susceptibility to quantum attacks, single points of failure, and cross-domain interoperability issues. Post-Quantum Cryptography (PQC) provides quantum-resilient security and Identity Mesh Architectures (IMAs) create decentralized and distributed identity management frameworks that support autonomous and cross-domain deployments. This paper presents a comprehensive analysis of PQC-IMAs through an examination of PQC, the IMA, security implications, deployment challenges, and future research directions. PQC-IMA integration allows for the creation of identity management systems that remain secure, resilient, and fault-tolerant when deployed in nationwide, large-scale 5G telecommunications networks and IoT systems. The solutions described in this paper can meet the challenges posed by the emerging Quantum Era and achieve operational efficiencies in connection ecosystems that are growing more and more complex and interconnected
