I'd say, submit a paper and elaborate on this. There are many approaches to cryptography besides primitives that count on problems hard to calculcate, such a steganograpby (hiding messages in images) and other forms of covert channels; https://github.com/mindcrypt/covertchannels-steganography
Mind that analog computing is a thing: https://en.wikipedia.org/wiki/Analog_computer And so is biological computing: https://en.wikipedia.org/wiki/Biological_computing You will find existing approaches of both applied to cryptography. Thanks for the note on the copyright. Cheers and good luck!
