AI, Quantum Computing Reshape Zero Trust Security as Q-Day Threatens RSA and ECC
3 articles · Updated · GovCon Wire · Jun 1
Zero Trust must evolve into an AI-powered, adaptive model as AI and quantum computing simultaneously widen cyberattack surfaces and strengthen defenses, Chuck Brooks argues.
AI is accelerating both sides of the fight: it can automate anomaly detection, risk scoring and incident response, but also enables polymorphic malware, deepfake phishing and machine-speed agentic attacks.
Quantum computing poses a deeper structural risk by threatening RSA and ECC encryption, raising the prospect of “harvest now, decrypt later” campaigns before cryptographically relevant quantum systems fully arrive.
Brooks says organizations should prioritize crypto-agility and post-quantum cryptography, while embedding AI into continuous authentication, micro-segmentation and policy enforcement with human oversight.
The broader shift makes Zero Trust less a static framework than a dynamic security ecosystem, with governance, workforce upskilling and cross-sector coordination becoming central to resilience after 2026.

2026 Quantum-AI Storm: Urgent Roadmap for Post-Quantum Cryptography and AI-Driven Cyber Defense
Overview
The report highlights the urgent cybersecurity risks posed by the coming of Q-Day, when quantum computers will be able to break widely used encryption like RSA-2048 and ECC. Quantum computers, using superposition and entanglement, threaten to undermine current encryption, making it critical to upgrade key agreement protocols now. This urgency is amplified by the 'harvest now, decrypt later' threat, where attackers are already collecting encrypted data to decrypt in the future. Progress toward Q-Day is accelerating due to advances in both quantum hardware and software, making immediate action essential to protect sensitive communications and data.
