37.3.3.5 Processing Field GF(p) and GF(2n)

The library can process arithmetic functions over GF(p) (or Zp integers) and GF(2n), when applicable. The choice of these processing fields is made using the following rules:

  • If a processing field is not applicable to the function, it is not mentioned and the Specific.GF2n bit has no effect.
  • If the function can support both processing fields, the choice is mentioned and the Specific.GF2n bit must be filled according to the choice.
  • If the function supports only one of the processing fields, the processing field is mentioned and the Specific.GF2n bit has no effect.
