i did not read the paper, but, if their model is a variant of OTP, with
a running stream cipher, it is possible, that it is "non-decryptable by
method" or semantically secure, or has no algorithmic decryption, only
brute force. however, as protein signalling (bio-informatics) is based
on a limited "alphabet" of amino acids, which is further reduced because
form requires that each amino acid will have only one mate
(opposite)--the shape & structure of proteins very much defines the
function of proteins; i am hard pressed to see, how they can come up
with an infinite number of possibilities. rather, the signaling would be
quite specific. in other words, well defined, not ambiguous. just the
opposite of OTP.

This is nonsense, right?
Yep.
Unbounded in the sense of relying on secrecy of the unbounded number of
algorithms?
The distinction between algorithm and parameter (along with other things) seem
muddled.
I commented on it is a few posts in sci.crypt. Here are trimmed highlights.
Jeffrey Goldberg wrote in Message-ID: <bqe4cnft6k...@mid.individual.net>:
[...]the 60 item bibliography of their paper cites only one source in
cryptography (and that is on quantum key exchange).
Somehow the first sentence of the paper doesn't inspire confidence either:
"It is often the case that great scientific and technological discoveries are
..."
[...]
What I see as I glance over this paper is that people who have been caught up in the
fadish understanding of "chaos theory" see that they get PRNGs out of their
dynamical systems (true enough).
But quite emphatically, the PRNGs that you get from most of this non-linear
dynamical systems are not cryptographically appropriate. Indeed, there are
tests that can distinguish whether the random sequences is likely to be from
such a system. If I understand correctly, even their noise filtering component
depends on exactly that technology.
