No they don't. You are receiving negative feedback because you are trying to adjust definitions that have been well-defined by the crypto community. When talking about the security of an encryption algorithm, the key distribution has absolutely nothing to do with it. Stop conflating the two.
>If we expand the definition of "encryption scheme" sufficiently to allow transmission of secrets outside of cryptographic channels, then OTP is not even close to the only unbreakable system.
Would you care to share with us some of these other unbreakable systems? Remember, the keys are the only thing that can be transmitted outside of the channel and they cannot be based on the information being encrypted.
Any scheme which allows sharing arbitrary amounts of random information is less than or equally secure as an OTP (security defined per symbol) since OTP reveals no information per symbol; also, it uses the minimum amount shared information to do so, provided your symbols are equiprobable.
Technically, either of these could be slightly more secure, in that they need not leak the length of the plaintext. For transmitting a single "yes" vs. "no" answer, that could be a fatal attack vector for a naive OTP.
My only point was that talking about one-time-pads as "unbreakable" encryption is not a useful discussion, since "unbreakable" and "encryption" need to be better defined.
If we expand the definition of "encryption scheme" sufficiently to allow transmission of secrets outside of cryptographic channels, then OTP is not even close to the only unbreakable system.
Only by explicitly defining attack vectors can we really get a good framework for reasoning about cryptography, and even then we know that we can prove an encryption technique is bad. For "goodness", all we can do is increase our confidence, until the day the confidence drops to 0.
Anyway, with this last salvo, I'll retreat from this conversation; it's pretty clear to me that my inane ramblings about semantics are as annoying to the community here as they are to me when other people make them.
