I think this question is simply a variation of points that have been made clear already in the past - no one legislates against "a set of 1s and 0s", "a set of letters", "a set of ink dots" nor, in this case, "a set of coefficients". Instead, legislation is created/updated for specific end results, and you're done.
For law enforcement purposes, I think it would be similar to a printing press: owning one is not a problem, but inserting printing rolls that look like dollar bills most definitely is.
