Functional Abuse?

  1. Presuming this can be expanded to cover some polynomial-trapdoor reduction…


  2. AdC Says:

    Is this an involution?


  3. The function itself, as opposed to the representation above?
    The above was meant to show the (reduction between) fn & its inverse…
    In terms of the fn itself;
    If a permutation, a point reflection, affine transform are involutions, then yes?
    I see where you’re headed with this I think… an XOR is an involution?


  4. AdC Says:

    yes, reflection is an involution.

    If the product between the transpose of f and f is equato to identity matrix, f is a permutation; and If f²=Id, this permutations is an involution.

    f(control=0,1, target=0,1) = (control, control XOR target) is an involution, because f²=Id.


  5. AdC(Alexandre) Says:

    if (control XOR target) is irreducible, then this XOR provides a hidden bit for inverting the function f

  6. Ok, thanks Alex! Give me some time to absorb all of that.
