Why Quantum Key Distribution (QKD) is impractical
In NSA's FAQ on Quantum Computing and Post-Quantum Cryptography, it is mentioned as
Q: Should I use a QKD system to protect my NSS from a quantum computer?
A: No. The technology involved is of significant scientific interest, but it only addresses…

Determination of the key rate of BBM92 Quantum Key Distribution (numerically)
I'm currently working on a Python Program which aim to return the secret key rate of a specific
Quantum Key Distribution protocol (Brassard, Benett and Mermin 1992 i.e. BBM92). A colleague will provide me with the result of this protocol.
However,…

Is manually provisioned Pre-shared key for symmetric encryption quantum-safe? What benefits would QKD solution have over using manual configured PSK?
RFC 8784 introduces a straightforward mechanism to use a pre-shared key to make modified IKEv2 key agreement resistant to a quantum computer Shor algorithm attack- thus providing a "quantum-safe" information channel. One use of this information…

Does the bit generated password using QKD protocols need to be converted to another base?
I am currently implementing some QKD protocols using Qiskit and I came up with the following question: After the protocol is finished, a true random password is generated using 0s and 1s, however, and here my question, do these passwords need to be…

Has anyone implemented the BB84 protocol?
Has anyone implemented the BB84 protocol and put it in production?
The BB84 is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984. It is the first quantum cryptography protocol.
I am thinking of incorporating…
