Location-Based Encryption Is A Quantum Reality

A research group led by computer scientists at the UCLA Henry Samueli
School of Engineering and Applied Science has proved that cryptography
— the practice and study of hiding information — that is based solely
on physical location is possible by using quantum mechanics. Such a method, the researchers say, allows one to encrypt and decrypt
data at a secure location without pre-sharing any cryptographic keys
that can be used to lock or unlock sensitive information. Read the full article. [Science Daily]

    It's a neat idea but it's just theory. Until it comes out, I think I'll stick with long-length encryption keys and asymetric encryption like PGP, GPG, and TrulyMail to protect my email.

    Theory of course. Maybe also the theory predicts that this quantum encryption is not so safe, do we really know everything about quantum entanglement? http://e1saman.wordpress.com/2010/08/30/heisenbergs-uncertainty-principle-and-quantum-memories/
