  Hi Rene,

 

  Yes, you're right. Good catch!

 

  regards,

Hi Dan:

 

I had a quick look at your document and there seems to be a small error (which is fortunately easy to correct):

 

To my understanding, the specific pick for the non-quadratic residue theta was to make sure that f(x)=theta would have no solutions in GF(q) or, in other words, that g(x):=f(x)-theta would be irreducible over GF(q). If so, the language in Section 14.4.4.2.3, 1)iii) should replace "is not irreducible" by "is irreducible over the field in question", with similar changes elsewhere (Step 2)iii) below this). I do not know what the rationale for the requirement 1)iv) {resp. 2)iv)} is, so cannot give feedback on whether that fits the intended design criteria.

 

Best regards, Rene

  Hello,

 

  I have uploaded 11-19/1817r0 which intends to update REVmd to be consistent with the

Internet-Draft from which we copied the hash-to-curve technique. Please take a look. I'd

like to discuss this on the teleconference tomorrow.

 

  regards,

 

  Dan.
