SpaceNews - British cybersecurity software developer Arqit is looking to sell a partly built satellite after scrapping plans for a space-based quantum encryption network.
Arqit said Dec. 14 it no longer needs satellites to deliver encryption keys that can resist attacks from quantum computers.
Instead, the company said it has developed a terrestrial distribution method that enables symmetric key cryptography without the risk and costs of building out a quantum communications network in space.
