A PRG is not a PRF ?

Thanks for the answer and the comments. I've updated the post. The idea looks like the one proposed by Richie.

Thanks very much for this example. Are there non cryptanalytical examples ?

comment What kind of operations are involved in NTRU?
Thanks very much for this detailed answer. I've read it and I certainly need to re-read it. Are lattice based crytographic algorithms more difficult to understand than number theory based ones ?

@dylan Thanks for the details. if $*$ is a multiplication, how we obtain a matrix for $h$? The multiplication of two polynoms does not give a polynom?

comment What kind of operations are involved in NTRU?
Thanks for your answer. If I've well understood, matrix-vector products are due to the use of the FFT algorithm. Can this also be used in the NTRU system ?

Thanks but why does Merkle trees need a preimage resistant hash function?

comment Signature and hash function properties
Thanks for youer answer. "Without preimage resistance you would also be unable to build hash trees." Why ? You speak about hash trees in terms of hash functions based on it, or you speak about an other application ?

comment Signature and hash function properties
@Bristol Thank you for your comment. That means that the pre-image resistance is closely linked to collision resistance. But if there are three properties, this means that we could satisfy a subset of them ?
