Non-Interactive Quantum Key Distribution. (arXiv:2304.02999v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
Quantum key distribution (QKD) allows Alice and Bob to agree on a shared
secret key, while communicating over a public (untrusted) quantum channel.
Compared to classical key exchange, it has two main advantages: (i) The key is
unconditionally hidden to the eyes of any attacker, and (ii) its security
assumes only the existence of authenticated classical channels which, in
practice, can be realized using Minicrypt assumptions, such as the existence of
digital signatures. On the flip side, QKD protocols typically …
