Experienced Cybersecurity Leader providing solutions to protect from Cyber attacks
The rapid advancements in quantum computing pose a significant threat to traditional cryptographic systems. With the potential to break widely-used encryption protocols, such as RSA and Elliptic Curve Cryptography, the need to prepare for post-quantum cryptography has never been more critical. As a trusted expert in Post-Quantum Consulting, I am here to shed light on the urgency of this matter and provide guidance on how organizations can navigate this transition effectively.
The Looming Threat: Within the next decade, the computing power and stability of quantum computers are expected to reach a level where they can render current public key encryption protocols vulnerable. This presents a grave concern for the protection of sensitive data, applications, and transactions that we rely on daily. Moreover, bad actors are already collecting data with the intention of decrypting it once quantum computers become capable—a tactic known as the "harvest now, decrypt later" threat. The transition to post-quantum cryptography will undoubtedly require a substantial effort that cannot be underestimated.
Understanding the Risks: To grasp the impact of quantum computing, it is crucial to recognize the vulnerabilities of common cryptographic algorithms. The following algorithms are at risk:
The advent of large-scale quantum computers will necessitate larger key sizes, longer output lengths, and render these algorithms insecure. It is imperative to act proactively to ensure the integrity and confidentiality of our systems.

Post-Quantum Self-Assessment: To aid in the transition to post-quantum cryptography, Entrust has initiated the Post-Quantum Cryptography (PQC) Self-Assessment. This assessment enables organizations to review their current readiness for new and emerging crypto threats. By identifying areas that lack readiness or impede crypto-agility, organizations can effectively plan for the future.
The NIST 2024 DHS Post-Quantum Cryptography Roadmap: While the National Institute of Standards and Technology (NIST) anticipates publishing a standard for commercial products in 2024, it is vital for organizations to start preparing now. Here are the essential steps to undertake:
a). Inventory your organization's systems for public-key cryptography applications. b). Categorize and determine the lifecycle of organizational data. c). Test the new post-quantum cryptographic standard in a lab environment, with implementation in a production environment awaiting the official release. d). Create a comprehensive plan for transitioning systems, including interdependence analysis, decommissioning outdated technology, and validating/testing products with the new standard. e). Develop acquisition policies, set new service levels, and survey vendors for compatibility and required foundational technologies. f). Alert IT departments and vendors about the impending transition. g). Educate and train your organization's workforce on the upcoming transition to ensure a smooth adaptation process.
Conclusion: The era of post-quantum cryptography is fast approaching, and organizations must act swiftly to safeguard their sensitive data and systems. By acknowledging the risks and following a strategic roadmap for transitioning to post-quantum cryptographic standards, organizations can maintain the security and resilience necessary to thrive in the quantum era. As a trusted expert in Post-Quantum Consulting, I am dedicated to assisting organizations on this transformative journey, ensuring their data remains secure in the face of quantum computing challenges.
