What is Post-Quantum Cryptography (PQC)?
Post-quantum cryptography (PQC) is about keeping data safe from quantum computers. It’s a way to keep information safe, even when quantum computers try to break it. Think of it like a super-strong lock that quantum computers can’t open.
Cryptography is very important for keeping our online world safe. It helps with online shopping, talking to friends, and storing important files. But, quantum computers could break some of these locks. That’s why we need PQC to keep our data safe.
PQC uses special techniques like lattice-based and hash-based cryptography. These methods are strong against quantum attacks. By using PQC, we can keep our data safe for a long time.
Why Do We Need PQC Now?
The threat of quantum computing is real. Organizations must act now to prepare for the quantum era. Quantum computers can break many current encryption methods, which could harm online security. This is why Post-quantum encryption is important, as it protects data from quantum attacks.
One big worry is the “harvest now, decrypt later” strategy. Attackers collect encrypted data today, planning to decrypt it when quantum computers are ready. This is a big threat, especially for data that needs to stay safe for decades. To fight this, using Quantum-proof cryptography is key to keep Secure communication and protect sensitive info.
Some companies, like Bittium, are already using quantum-safe algorithms. For example, Bittium’s SafeMove Mobile VPN and Secure Call use a mix of old and new encryption. This mix keeps data safe, even if quantum-safe algorithms have flaws.
To get ready for the quantum era, companies should check their data for risks. They should then start moving to new encryption methods and protocols. This will keep Secure communication safe from quantum threats. So, Post-quantum encryption and Quantum-proof cryptography are crucial for the future of online security.
How PQC Differs from Traditional Cryptography
Quantum-safe cryptography, or PQC, keeps data safe from both old and new attacks. It’s different from old cryptography because it can fight off quantum attacks. This is thanks to special PQC algorithms, like lattice-based and code-based cryptography.
Quantum resistance is key in PQC. It keeps our data safe from quantum computers. These computers could break many old encryption methods. So, making PQC algorithms is vital for keeping our data safe.
- Use of quantum-resistant algorithms
- Ability to resist quantum attacks
- Long-term security against both classical and quantum attacks
PQC is very important for keeping data safe in the future. Its development is crucial for a secure world.
Key Players in the PQC Field

Understanding the Algorithms Behind PQC
PQC algorithms are key for keeping data safe from quantum computers. They make sure our data stays secure, even when quantum computers get stronger. These algorithms include lattice-based, code-based, and hash-based cryptography.
A PQC algorithm is vital for safe encryption and decryption. The National Institute of Standards and Technology (NIST) has picked some for standard use. These include FIPS 203 ML-KEM, FIPS 204 ML-DSA, and FIPS 205 SLH-DSA.
The following table provides an overview of some common PQC algorithms:

| Hash-based cryptography | Based on the hardness of problems related to hash functions |
These algorithms help keep our data safe from quantum attacks. They are a big part of making sure our encryption stays strong.
The Transition to Post-Quantum Cryptography
As quantum computers get stronger, we must switch to new encryption. This means checking our current encryption, finding what needs to be changed, and planning how to switch. We aim for secure communication with post-quantum encryption.
Using quantum-proof cryptography is key. NIST picked CRYSTALS-Kyber and CRYSTALS-Dilithium for their top choices. Here’s how to start using PQC:
- Check your current encryption to see what needs to be updated
- Make a plan for switching to PQC
- Start using quantum-proof algorithms like CRYSTALS-Kyber and CRYSTALS-Dilithium
By doing these steps, we can smoothly move to post-quantum cryptography. This keeps our secure communication safe from new quantum threats.
Switching to PQC is very important for keeping our digital talks safe. We must focus on this to stay safe from new dangers.

Potential Challenges of Implementing PQC
Using post-quantum encryption has big challenges. These include technical and money problems. One big issue is needing new hardware and software for quantum-proof cryptography. This can cost a lot, especially for small groups.
There are technical issues too. For example, keys get bigger, needing more space and memory. Quantum-resistant cryptographic systems use much bigger keys than old ones. This makes encryption and decryption slower, affecting how fast things work.
Also, changing to post-quantum cryptography might make old systems not work together. Here are some main problems:
- Keys get bigger, needing more space and memory
