Post-Quantum Identity Mesh for Autonomous 5G, IoT, and National Connectivity Systems Quantum-Resilient Identity Architecture for Future Digital Infrastructure.

Abstract:

The rapid expansion of 5G networks, Internet of Things (IoT) ecosystems, and national digital connectivity systems has fundamentally changed how societies, industries, and governments operate. These highly distributed and autonomous environments depend on digital identity as the core mechanism for authentication, authorization, and trust. However, today’s identity management systems rely heavily on centralized architectures and classical cryptographic algorithms that are increasingly vulnerable to large-scale cyber threats and emerging quantum computing capabilities.

This keynote examines the growing risks posed by quantum-era attacks, centralized identity models, and cross-domain interoperability limitations within 5G and IoT infrastructures. It introduces a Post-Quantum Identity Mesh as a future-resilient solution that combines quantum-resistant cryptographic techniques with decentralized, distributed identity architectures. By eliminating single points of failure and enabling continuous, autonomous identity verification, the Identity Mesh supports secure device onboarding, machine-to-machine communication, and cross-domain trust across national and global networks.

The presentation outlines the problem, explains why existing approaches are insufficient, and demonstrates how Post-Quantum Identity Mesh architectures can deliver scalable, interoperable, and resilient identity management for next-generation connectivity systems. The session concludes with an assessment of key benefits, deployment challenges, and future research directions, emphasizing the need to transition toward quantum-resilient identity frameworks to sustain trust in the digital infrastructure of the future.
