Navigating the NIST Post-Quantum Cryptography (PQC) Roadmap
The world of cybersecurity is evolving rapidly, and with it comes the need for organisations to adapt to new standards and technologies. The National Institute of Standards and Technology (NIST) has recently released a clear roadmap for the transition to post-quantum cryptography (PQC). This roadmap sets firm deadlines for the deprecation and disallowance of legacy algorithms like RSA and Elliptic Curve Cryptography (ECC).
Here’s what you need to know, what these deadlines mean for your organisation, and how Unsung can help you prepare for a quantum-secure future.
NIST Deadlines: Key Dates You Can’t Ignore
- 2030: RSA and ECC algorithms will be deprecated. Systems using these algorithms will no longer comply with NIST-approved security standards.
- 2035: RSA and ECC algorithms will be disallowed. Organisations still reliant on these will face serious risks, including compliance violations and interoperability issues.
These dates mark the end of an era for legacy cryptography and set the stage for post-quantum cryptographic standards.
The Quantum Computing Revolution and Its Impact on PKI and Cybersecurity
Quantum computing is no longer the stuff of science fiction. With advancements accelerating, these powerful machines are poised to solve problems beyond the reach of legacy computers. While this innovation holds immense potential for fields like medicine, logistics, and artificial intelligence, it also poses a serious challenge to current cryptographic systems.
Public Key Infrastructure (PKI), the backbone of secure digital communications, relies on algorithms like RSA and Elliptic Curve Cryptography (ECC). These algorithms are based on the computational difficulty of certain mathematical problems, such as factoring large prime numbers or solving discrete logarithms. Quantum computers, with their ability to perform massive parallel computations, could break these algorithms in a matter of hours—or even minutes—rendering today’s encryption obsolete.
The implications for cybersecurity are profound:
- Data Exposure: Encrypted communications, sensitive data, and digital identities could become vulnerable to decryption by adversaries with quantum capabilities.
- Compliance Risks: Organisations reliant on legacy cryptography will struggle to meet evolving regulatory and security standards.
- Operational Disruption: Systems not upgraded to post-quantum cryptography (PQC) may fail to interoperate in a secure ecosystem, leading to widespread disruption.
The threat is not theoretical. Data being encrypted today with RSA or ECC could be stored by attackers and decrypted later when quantum computers become available—a strategy known as “harvest now, decrypt later.” This makes the transition to quantum-resistant algorithms not just a future concern but a present-day imperative.
By acting now to adopt PQC-ready systems, organisations can mitigate these risks and ensure their operations remain secure in a quantum-enabled future. Unsung is here to guide this critical transition.
Impacts on Your Organisation
Technology Stacks
Legacy systems relying on RSA or ECC will face compatibility and security issues:
- Post-2030, systems using deprecated algorithms may still function but will not align with modern security policies, exposing organisations to risks.
- Post-2035, these systems may completely fail to integrate with PQC-ready infrastructure or be outright disallowed by regulators.
Processes
Transitioning to PQC algorithms will require significant updates to PKI operations, including:
- Crypto-asset audits to identify where legacy algorithms are in use.
- Key and certificate migration to ensure seamless functionality with quantum-resistant algorithms.
- A shift towards crypto agility, enabling organisations to adapt quickly to new cryptographic standards in the future.
Why Act Now?
While 2030 may feel distant, the transition to post-quantum cryptography is a complex, multi-year endeavour. Organisations that start planning now will:
- Avoid last-minute scrambling and potential disruptions.
- Align with regulatory requirements well before deadlines.
- Ensure their systems remain secure and interoperable in a post-quantum world.
The NIST roadmap provides the perfect opportunity to assess your organisation’s readiness and set a clear plan to meet these milestones.
