Quantum-safe encryption

PQC and QKD: Your data security for tomorrow

Use quantum-safe encryption now

Future-proof encryption for optical networks

Quantum computers bring new opportunities, but also risks: The supercomputers give hackers unimagined possibilities for decrypting data. Current encryption methods will soon no longer be sufficient. This is why fast, crypto-agile action is crucial. We support you with information, advice and modern, quantum-safe solutions. Our services range from pragmatic, mathematical encryption (PQC) to innovative exchange procedures (QKD) based on quantum mechanics, which guarantee maximum protection in the long term.

 

PQC: Quantum security for your DWDM connections

Post-quantum cryptography (PQC) uses advanced mathematical methods to protect against the threats posed by quantum computers. One of the best-known PQC encryption methods is currently “McEliece”, which is recommended by both NIST and the BSI.

Post Quantum Cryptography new or as an upgrade

The McEliece encryption method is installed as software. It is not necessary to replace the hardware. If you have previously used AES-256 for encryption, you can easily switch to McEliece with a firmware upgrade. 

 

PQC: Your advantages

  •  Up-to-date mathematical solution for more quantum security: hackers will not be able to decrypt the encrypted data even with the help of quantum computers

  • Interoperability with existing systems

  • Open for software updates based on future PQC standards

  • Minimal impact on signal propagation times, data throughput and performance

Quantum Key Distribution uses quantum mechanics

Current encryption methods are based on mathematics and could be easy for quantum computers to crack in the future. Quantum cryptography itself uses the laws of quantum mechanics. Photons, i.e. light quanta, are sent via optical connections.

Any change is noticeable

Quantum physics shows that any observation disturbs a quantum state. QKD protocols guarantee that eavesdropping attempts immediately affect photon transmission. This interference leads to detection errors that are noticed by legitimate users. This means that any eavesdropping attempt in a quantum-encrypted channel is detected immediately. Even with a powerful quantum computer, an eavesdropper cannot circumvent quantum mechanics and will be detected.

QKD for your data center link

Two QKD devices are connected via fiber optics and continuously distribute key material that is stored at each endpoint. This works up to an optical attenuation of 24 to 30 dB, which corresponds to a range of around 120 km, depending on the network quality. This is why these systems are often used in LANs or MANs, e.g. on company premises or for linking data centers.

Compatible with Ethernet and Fibre Channel

“Trusted Nodes” enable the solution to be extended to greater distances.With “key hopping”, keys are generated at the start node and transmitted securely to the end node. Many manufacturers offer quantum-capable devices that accept keys from QKD devices. These encryption devices are compatible with Ethernet and Fiber Channel, with link bandwidths up to 10 Gbps and aggregated bandwidths up to 100 Gbps.

 

QKD: Your advantages

  • provable, information-theoretical security for your data transmission with maximum protection against “store now, decrypt later” attacks

  • Physical process - cannot be attacked with computing power

  • Interoperability with DWDM hardware - e.g. from Adtran

Working together for quantum-safe encryption

For future-proof encryption in the quantum age, collaboration between companies and research is important. Our technology partner ID Quantique from Switzerland is a leader in quantum-safe cryptography, scientific instrumentation and random number generation - technologies that are used by governments, companies and research labs in over 60 countries worldwide.

The EU is investing heavily in QKD projects such as “OpenQKD” as part of the Quantum Flagship program. The aim is to establish robust QKD networks in Europe. dacoso experts are involved in the further development of these groundbreaking technologies and work in leading research groups and networks.
