Struct WhirParams 

pub struct WhirParams {
    pub k: usize,
    pub log_final_poly_len: usize,
    pub query_phase_pow_bits: usize,
    pub proximity: WhirProximityStrategy,
    pub folding_pow_bits: usize,
    pub mu_pow_bits: usize,
}

Configurable parameters that are used to determine the WhirConfig for a target security level.

The *_pow_bits fields set proof-of-work grinding difficulty in bits, i.e. hash evaluations. The security those bits provide depends on the cost of the grinding hash (the transcript hash): cheaper hashes make each grinding attempt cheaper for an attacker. When changing the configuration—especially the hash function—revisit the PoW difficulty so it still meets the intended security against an attacker grinding with that hash. See crate::soundness.

Fields

k: usize

log_final_poly_len: usize

WHIR rounds will stop as soon as log2 of the final polynomial length is <= log_final_poly_len.

query_phase_pow_bits: usize

proximity: WhirProximityStrategy

Proximity regime to use within each WHIR round. This is used to determine the number of queries in each round for a target security level.

folding_pow_bits: usize

Number of bits of grinding to increase security of each folding step.

mu_pow_bits: usize

Number of bits of grinding before sampling the μ batching challenge.
