Re: No such thing as secure
"Just stuff that hasn't been cracked yet."
That's easy to say, but much harder to prove.
Lets only focus on the fundamental security across the wire and not implementation faults, since implementation faults can implicitly be fixed (and therefor contradicts your statement that there is "no such thing as secure").
With regards to PKI, there are two possible cracks.
1. We discover a mathematical way to boil NP complete problems down to polynomial time without the need for brute force.
2. We discover a way to solve NP complete problems quickly, say using a theoretical scalable quantum computer.
In order to back your assertion for PKI, you would have to prove either of the above is feasible.
With regards to quantum encryption, there is theoretically nothing one can do on the line to uncover the data. Quantum entanglement creates a continuous stream of bits which can be used as a one time pad of infinite length.
To prove your assertion for Q-E, you'd need to invalidate the currently accepted principles of quantum mechanics to reproduce the random bit stream.
You may be right, but until you can prove it, the statement is at best an educated guess.
