I am extremely skeptical about quantum cryptography. First all of the articles I have read about the technology use the same mathematical concepts to encrypt and decrypt a message. Nothing about quantum cryptography actually changes physical characteristics of math. That is obvious. There have been mentions that the act of eavesdropping could never happen either which is more absolute ********. A man in the middle attack is a man in the middle attack regardless. Relaying a message after interception does not change the physical properties of the message in a public key encryption system. In fact... I know of no "eavesdroppers" in the current world of encryption/decryption hacks. You cannot watch a message going by without actually intercepting it. There is nothing that I can even begin to accept as a possible reality about this supposed new cryptography. I think it's total hype and am ready to call it a flat out con. Can anybody tell me otherwise?
