WebQuantum-key-Distribution (QKD) can be used to securely exchange cryptographic keys among different communication parties by using QKD nodes (also known as “trusted nodes”). Usually, trusted nodes integrate QKD modules and a distributed key manager, which demands the meeting of strong security requirements.

"WebDoes it really matter if we used AND, OR or XOR with the one-time pad? The answer is yes, and it’s extremely important to understand why. Recall from the previous article that AND has a 75% chance of outputting 0 and a 25% chance of outputting a 1. While OR has a 25% chance of outputting 0 and 75% chance of outputting 1.
