comment Are there cryptographic hash functions that can be computed using only paper and pen without leaking any information about the plaintext?
Aha, I understand. Might be worth incorporating that into the question - I interpreted the read only random access store as a piece of paper with the message on. If you have an example usage scenario in mind that would be interesting.

Can you expand on why you have your side channel constraint? It doesn't seem to fit in with my model of what you're trying to achieve. The original (sensitive) information is on paper with the user. Why can they not create additional sensitive information and then either destroy it or leave it along with the original?

Thanks for the info and good explanations and also the pointer to the hash function lounge - see my answer for what came of it.
