Advancement and Modernization of Public Key Infrastructure (PKI) in the Evolving Artificial Intelligence (AI) and Quantum Landscape.

Abstract:

Public Key Infrastructure (PKI) has long served as the foundation of secure digital interactions, supporting authentication, encryption, and integrity across global systems. However, as artificial intelligence evolves and quantum computing approaches viability, the security guarantees of classical cryptographic algorithms face unprecedented threats. AI is accelerating advancements in cryptanalysis and may soon assist in exploiting vulnerabilities at a scale and speed that traditional PKI was never designed to withstand. Combined with the potential of quantum computers to break widely used algorithms such as RSA and ECC, this convergence represents a critical turning point for digital trust.

This session explores the need to modernize PKI in response to this shifting threat landscape. It introduces Post-Quantum Cryptography (PQC) as a strategic imperative and explains how hybrid PQC models can ensure a smooth transition while maintaining backward compatibility. The talk will outline how to build cryptographically agile systems that are prepared to operate securely across both classical and post-quantum environments. By understanding the evolving role of AI and quantum computing in the context of cryptographic risk, attendees will gain actionable insights to begin future-proofing their infrastructure before these emerging threats become operational realities.
