Quasar Encryption
Does anyone have the faintest clue what they’re talking about here? If I had to guess, it’s just another random-number generator. It definitely doesn’t sound like two telescopes pointing at the same piece of key can contruct the same key—now that would be cool.
The National Institute of Information and Communications Technology is trying to patent a system of encryption using electromagnetic waves from Quasars.
According to The Nihon Keizai Shimbun, this technology is used to take cosmic radio waves are received through a radio telescope, encrypt and then retransmit them. Because cosmic waves are irregular, it is virtually impossible for others to decipher them. A spokesman is quoted as saying that the system could be used for the transmission of state secrets and other sensitive information.
The radio telescope can decipher the information by observing the cosmic wave patterns emitted by a particular quasar selected in advance. Even if the encrypted data is stolen, it is impossible to read it without the appropriate quasar’s radio signals.
The only way to really break the code is to know which radio telescope the coder is using and what Quasar it is pointing at. Only then do you have a slim chance of decoding it.
I can see the story on the home page of Nikkei.net Interactive, but can’t get at the story without a login.

It does sound like they are using two radio telescopes and a radio set up…
RT1 picks up random data stream from quasar…
RT2 picks up random data stream from same quasar…
User1 encrypts signal over the output of RT1 and broadcasts it. (is this just an XOR? It sounds like it to me…)
User2 takes broadcast signal and decrypts it using the output from RT2…
There needs to be a way to synchronise the encryption/decryption and that bit could be interesting… The rest of it is just a way to make sure that you have the same random data stream available to both users.
