Correcting Post-Quantum Cryptography Myths through a Study-based Method to Enterprise
Quantum Readiness
31 July, 2026
Quantum computing is the latest buzzword in IT as of late. And all the buzz has boiled down to the paranoia of the supercomputer’s ability to break the very foundation of today’s digital trust.
As much as we’d like to dispel fearmongering, there are real technological risks at play—all with your data integrity on the line. The comfort we’ll offer is that contingencies can be put in place.
It is a myth to say that all encryption will be broken by quantum computing. Once the new technology stabilizes, attacks that utilize it will be targeted and exploratory, giving you the time to focus your efforts on priority critical data and facilitate a sustainable post-quantum journey.
What Is HNDL?
Harvest now, decrypt later (HNDL) is a cyberattack strategy that collects protected and encrypted data and stores it until adequate technology capable of brute-force decryption becomes available to attackers. This allows them to take advantage of still-critical data gathered before the quantum break.
Harvest now, decrypt later entered the quantum computing discourse following its renewed development around 2022. It is now gaining greater awareness as the quantum timeline continues to progress at unprecedented speeds.
But awareness does not equal preparation. Attackers are eager to make quick money by exploiting vulnerabilities in organizations and critical infrastructure.
Are You Spared From the Post-Quantum Break?
In cybersecurity, long-life data refers to sensitive information that remains valuable and confidential for many years or even decades. In this regard, the most critical data in need of protection includes information heavily involved with or related to:
- Blockchains and digital wallets
- Healthcare data
- Long-term financial audits
- Privileged access
- Legacy infrastructure
This leaves industries and organizations such as government, banking, defense, finance, and those heavily reliant on sensitive digital assets as major targets for HNDL attacks.
Encryption does not exist only during the transport and storage of data. Vulnerable standard encryption may also serve as the primary security layer within your applications, APIs, devices, VPNs, and third parties handling all your data—both in storage and in transit.
Encryption ensures privileged access to:
- Private protocols
- Data inside network stacks
- Authentication systems
These controls ensure that only secure connections, authorized users, and trusted endpoints can access your data. Break the encryption, and the entire network of data could become exposed.
Can You Park It for Now?
The flip side of dispelling doomsday myths about post-quantum cryptography is complacency. Many local organizations still operate on legacy systems that will inevitably become obsolete by Q-Day because they cannot support emerging cryptographic requirements.
However, cryptographic migration cannot happen overnight. It requires years of careful planning to ensure that data and environments are secured comprehensively and in the order in which protection is most urgently needed.
Your Place in the Q-Day at This Point in Time
Organizations must move beyond awareness of the threat and develop an awareness of their own vulnerabilities.
All migration scoping must begin with a comprehensive cryptographic inventory. This means keeping track of all existing encryption and cryptographic assets across your environments, including:
- Algorithms
- Cryptographic keys
- Digital certificates
- Security protocols
- Affected systems
- Data-retention periods
Effective cryptographic asset management is essential for ensuring compliance, maintaining control, and enabling automation. These are foundational requirements for managing risks. A proper inventory also establishes the basis for benchmarking risks and setting priority indexes.
Crypto-Agility Over Unabridged Migration
Quantum alarmists may urge organizations to migrate immediately in preparation for Q-Day. However, a large-scale migration at this point can become a costly and rushed undertaking that does not necessarily guarantee quantum security because of system rigidity.
What organizations should prioritize is assessing their crypto-agility.
Crypto-agility is the oversight and capability needed to adapt to advancing cryptographic requirements, particularly in the areas of:
- Modularity
- System architecture
- Governance
- Cryptographic management
It recognizes that security threats exist and are constantly evolving. This means preparing system primitives or building blocks to be portable, interoperable, and organized according to priority and data longevity.
Organizations can then adopt appropriate post-quantum approaches, including:
- Lattice-based cryptography
- Multivariate cryptography
- Hash-based cryptography
- Code-based cryptography
Through a systematic approach, organizations can avoid an unrealistic large-scale migration that requires rebuilding their entire system.
Where Do You Stand in This Upheaval?
Your move toward quantum readiness should be guided by understanding and awareness, not fear.
Our post-quantum cryptography experts recommend a five-stage process:
- Assessment
- Planning
- Pilot testing
- Migration
- Maintenance
Requirements may vary depending on the complexity of each organization’s data systems. However, foundational and practical steps must always be present in every quantum journey, regardless of the technology or partnership spearheading the migration effort.
Spearhead Your Journey With These Practical First Steps
- Assign ownership—Assign executive, technical, and business-process accountability to the people who will steer the organization’s direction across every area affected by the migration.
- Identify long-life sensitive data—Account for personally sensitive, financially sensitive, health or medical, credential, government, security, and corporate business data. Pay particular attention to information that is difficult to recover or invalidate and whose misuse could continue for years.
- Begin cryptographic discovery—Identify your cryptographic assets, the methods currently being used, and the data they protect.
- Engage technology vendors—Partner with a vendor whose core capabilities align with current NIST compliance directives, who provides crypto-agile frameworks that can adapt to your systems, and whose proposed roadmap offers a realistic and secure timeline.
- Prioritize critical systems—Prioritize systems and data that are safety-critical, project-critical, and business-critical.
- Develop a phased migration roadmap—Treat your journey as a multi-year governance program that accurately assesses risk, divides the migration into reasonable phases, and tracks progress.
We are witnessing the rewriting of modern computing as we know it. However daunting this may seem, organizations can protect themselves from its implications when the right efforts are spearheaded, viewed through the right lenses, and tackled using the right approach.
