Quantum-safety enabling cybersecurity reference infrastructure model for edge and access services

Abstract

The emergence of large scale quantum computing threatens the long term security of widely deployed public key cryptography, creating an urgent need for quantum safe migration across heterogeneous edge and access infrastructures. We present a scalable reference architecture that supports Post Quantum Cryptography (PQC) adoption in resource constrained, multi vendor environments characteristic of edge and access services. The model integrates continuous cryptographic inventory, lightweight PQC for constrained devices, protocol level modernization, interoperability, and crypto agility, while addressing long term data protection and device integrity across distributed systems. Our experimental setup demonstrates PQC ready communication, secure cross domain interactions, and AI assisted monitoring under realistic edge network conditions. The results provide a practical and extensible reference model for organizations seeking to reduce cryptographic exposure and transition toward quantum safe security in complex, large scale edge and access services.
