How do you generate a one-time-pad? a one time pad must be by definition truly random, and be used only once. and if you can send the Securikey via a secure channel at the same time as the message, then you don't need the OTP.
I should also mention that the problem with 'generating' an OTP via any mechanical or algorithmic means is impossible as at best an OTP will only be pseudo-random, and therefore with identical inputs (assuming it is possible, which we can assume here for the sake of theory and security), the same OTP can be generated, thus breaking our assumption/necessity of non-deterministic output.
I'd say more but I'm on my way to work. - -- tabris - - I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a butterfly dreaming I am a man. -- Chuang-tzu -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux)
