Quantum Solutions and the Impending Decryption Threat: Preparing for Q-Day
This session explores the growing risk posed by quantum-enabled decryption, referred to as Q-Day, the point at which sufficiently powerful quantum computers could undermine widely used public-key cryptosystems. Attendees will examine what this shift means for today’s networks, including the “harvest now, decrypt later” risks and the operational impact of large-scale cryptographic compromise. The discussion will also look at quantum technologies as part of a forward-looking security strategy. Panelists will discuss where these approaches are most relevant, how they can complement broader migration efforts, and what organizations should be doing now to build resilient, tamper-evident communications that can withstand future quantum adversaries.
Who Should Attend:
Cybersecurity professionals, network engineers, IT security architects, and executives responsible for data protection in AI-driven environments. This session is especially valuable for those in finance, healthcare, government, and critical infrastructure sectors where encryption compromise would have severe consequences.
What You Will Learn:
- The mechanics and realistic timelines of quantum decryption threats, including the impact of algorithms like Shor’s on current cryptographic standards.
- Core principles of quantum networking, such as QKD and entanglement distribution, and how they differ from and complement classical security methods.
- Strategies for assessing organizational exposure to quantum threats and planning migration to quantum-resistant and quantum-secured architectures.
- Practical first steps for evaluating, piloting, and implementing quantum networking solutions to protect sensitive data flows against future decryption risks.
