The future of cryptography is at a turning point. The evaluation of algorithms for post-quantum cryptography (PQC) by the U.S. National Institute of Standards and Technology (NIST) has paved the way for a new era of IT security, with the new encryption algorithms available now. Designed to withstand the threats posed by quantum computing, they take your IT infrastructure into the post-quantum age. We’ll show you how your company can take advantage of this while preparing for new challenges at the same time. The answer is simple: crypto agility.
Crypto agility? It's a must!
Crypto agility describes the ability of an IT system to react quickly and effectively to changes in cryptographic algorithms and protocols. In a world where cyber threats are on the rise, this cryptographic agility is crucial. The risks posed by quantum computers make this flexibility absolutely essential. Why? Experts expect quantum computers to compromise many of the encryption methods used today in very short order. Act now to ensure now that your systems are both secure and future-proof.
What does post-quantum cryptography mean?
Post-quantum cryptography (PQC) encompasses cryptographic methods that are resistant to attacks by quantum computers. The CRYSTALS-Kyber, CRYSTALS-Dilithium and Sphincs+ algorithms developed by NIST are specifically designed to remain secure in an era of powerful quantum computers. Companies that switch to PQC gain a clear edge in their defence against future threats.
The four pillars of crypto agility
Modularity is the be-all and end-all of any crypto agile solution. Your IT infrastructure must have a modular structure that enables you to update encryption functions easily. This is the only way to replace individual components without having to redevelop the entire system.
1. Flexibility |
Crypto agile systems need to be flexible so they can react to new threats. This means that different encryption algorithms have to be supported and it must be possible to implement new security protocols. |
2. Open standards |
Transparency and openness are essential for crypto agility. Systems need to be based on open standards, as this is the only way we can guarantee interoperability and future customisation. |
3. Lifecycle management |
The cryptographic components need to be updated regularly and managed in a structured manner. This includes the continuous monitoring of security vulnerabilities and rapid response to new threats – with no exceptions. |
4. Safety assessment |
Regular audits by independent organisations ensure that your systems comply with the latest security standards. |

The era of crypto agility starts now
Threats from quantum computing are far from fictional. Quite the contrary: they’re increasingly becoming an integral part of our reality. Since the course for the new era of IT security has been charted, there are no more excuses. Crypto agility is no longer a “nice-to-have”, but has become a match-critical “must-have”. The right time to prepare for the challenges of the post-quantum era is now. An IT infrastructure geared towards crypto agility enables you to secure your data and thus the future of your company.
