1 - Handling sensitive data in your company network
Your users create and handle sensitive company data every day, either on their laptops or smartphones. How is this information transmitted and stored securely? One of the most important tools to secure your data is cryptography. It has to achieve three things...
2 - What's the problem? – The (Quantum) Computing Threat
Elliptic-Curve Diffie-Hellman Key Exchange (ECDHE) and RSA are prominent examples of public key cryptography. This name stems from the fact that two keys are created, one private and one public. The public key is shared with your communication partner which al...
3 - Where does it hurt? – Your company's network architecture
In your company, it is not only the employees' laptop or smartphone that requires cryptography. Instead, there will be a portfolio of networked devices that take care of encrypting, transmitting, and decrypting data, for example in order to connect two company...
4 - When to act?
Is your information at risk right now? The answer is yes, in light of the so-called store-now-decrypt-later attack. Attackers store your encrypted data traffic and decrypt it once a sufficiently large (quantum) computer becomes available. If this happens befo...
From classical key exchange to quantum-safe key supply
Most of today’s encrypted network traffic still relies on asymmetric cryptography for key exchange, for example mechanisms based on RSA or elliptic curves. These methods are widely deployed and secure against classical computers, but they are not designed to w...
Typical two-node QKD setup
A typical Quantum Key Distribution (QKD) setup connects two trusted locations, here called Node A and Node B. Each node contains the components needed to generate, manage and use cryptographic key material for encrypted communication between the two sites. At...
