Reflective satellites may be the future of high-end encryption

Quantum key distribution is regularly touted as the encryption of the future. While the keys are exchanged on an insecure channel, the laws of physics provide a guarantee that two parties can exchange a secret key without knowing whether they’re being overheard. This unencrypted-but-secure form of key exchange circumvents one of the potential shortcomings of some forms of public key systems. However, quantum key distribution (QKD) has one big downside: the two parties need to have a direct link to…
