comment Encryption algorithm designed to be easy to decrypt by machine but impractical to decrypt by hand
I'm guessing this is supposed to be a heavy-duty analogue of ROT13. $\;$

comment A one way Function provably reversible at N applications with the same seed?
No, I was suggesting that f be evaluation of s at A, where s is a polynomial of degree at most N-1. $\:$ However, I now realize that the decoder also needs to know what the finite field is. $\hspace{1.45 in}$

comment A Doubt with the twisted-PRF
"So", that's why they don't claim that the existence of a PRF implies the existence of one for which the "Original Twisted PRF Trick"'s F would be insecure. $\:$ (For some reason, it won't let me log in to chat.) $\hspace{.32 in}$

comment A Doubt with the twisted-PRF
There are certainly "problems with the proof in ... PRF Trick"; that's the paper's point. $\hspace{1.32 in}$

comment A one way Function provably reversible at N applications with the same seed?
Do you want s to remain hidden against an essentially unbounded number of queries that don't include any such chains, or just against less than N total queries? $\;$

comment Large file validation on an embedded system through hash and encryption
It would probably be better to sign "the MD5 hash with a private key and return" a signed "hash to the embedded system", rather than trying to use encryption for that purpose. $\;$
