Expand description
Support for the rank 4 extension field of the base field.
Structs§
- Fp4
- Instances of
Fp4are elements of a finite fieldF_p^4. They are represented as elements ofF_p[X] / (X^4 - 11). Basically, this is a big finite field (about2^128elements), which is used when the security of various operations depends on the size of the field. It has the fieldFpas a subfield, which means operations by the two are compatable, which is important. The irreducible polynomial was choosen to be the most simple possible one,x^4 - B, where11is the smallestBwhich makes the polynomial irreducable.
Constants§
- EXT_
SIZE - The size of the extension field in elements, 4 in this case.
