Dan Bernstein and I were introducing 'clock crypto' for real clocks.<br>
Of course you'reĀ 'clock crypto' any way you want but I find it to<br>
be confusing with our way of presenting elliptic curves via clocks,<br>
where we use proper arithmetic on the clock (=circle). For our<br>
presentation the comment about 'distorted clocks' makes sense, I<br>
don't understand what it means if you take the clock to be just the<br>
integers mod some prime.</blockquote><div><br></div><div>I got similar feedback from Tom Ptacek so... duly noted.</div><div><br></div><div>I was trying to make a visual allusion to hours being points on a circle, without really describing that in prose (or arithmetic).
