Adopting Post-Quantum Cryptography: Strategies and Best Practices for Implementation
In recent years, quantum computing’s amorphous but indispensable potential has underpinned the rapid development of post-quantum cryptography. This cutting-edge crypto design is meant to resist attempts by quantum computers to crack conventional cryptographic systems. Now that the National Institute of Standards and Technology (NIST) has officially announced the Post-Quantum Cryptography Standardization Project, it’s an opportune time to delve into the history leading up to this momentous development and understand its implications for security in a quantum future.
An initiative several years in the making, the NIST project aims to identify, standardize, and promote robust cryptographic algorithms capable of withstanding the quantum computing threat. This isn’t the first occasion though that NIST has played midwife to a new era in cryptography. It shepherded in the 1977 adoption of the Data Encryption Standard (DES) and again in the early 2000s, when the Advanced Encryption Standard (AES) replaced DES. The rigor and transparency that characterizes the institute’s approach to such weighty matters has been exhibited yet again in the drafting of the current post-quantum standards. Rigorous rounds of selection and multiple public comment periods have helped cherry-pick the best algorithms, carefully balancing security, efficiency, and versatility of implementation.

| 2000+ | Advanced Encryption Standard (AES) |
| 2018+ | Post-Quantum Cryptography Standards |
While embracing the fortified security that post-quantum cryptography promises might seem like a no-brainer, it’s equally important to strategize its implementation. Entities must consider their specific security requirements, identify vulnerable systems, and prepare to grapple with possible teething issues, all while keeping the time crunch imposed by the ‘quantum deadline’ in mind. Adoption strategies must also pay attention to the fact that current cryptographic infrastructure is largely unsuited for a post-quantum overhaul, calling for a gradual approach. Irrespective of the challenges, the post-quantum cryptography wave is rolling in, and the NIST has, once again, delivered a much-needed roadmap to navigate it.
