impl<P> Pedersen for P

source§

fn hash( x: &FieldElement<<P as PedersenParameters>::F>, y: &FieldElement<<P as PedersenParameters>::F>, ) -> FieldElement<<P as PedersenParameters>::F>

Implements Starkware version of Pedersen hash of x and y. Divides each of x and y into 4-bit chunks, and uses lookup tables to accumulate pre-calculated points corresponding to a given chunk. Accumulation starts from a “shift_point” whose points are derived from digits of pi. Pre-calculated points are multiples by powers of 2 of the “shift_point”. Read more
source§

fn lookup_and_accumulate( acc: &mut ShortWeierstrassProjectivePoint<<P as PedersenParameters>::EC>, bits: &[bool], prep: &[ShortWeierstrassProjectivePoint<<P as PedersenParameters>::EC>], )

Performs lookup to find the constant point corresponding to 4-bit chunks of given input. Keeps adding up those points to the given accumulation point.
