RSA VDF

Simple RSA VDF in Rust (Wesolowski18)

let t = BigInt::sample(20); //time parameter 
// One public setup can work for many VDFs
let setup = SetupForVDF::public_setup(&t); 


// 1. challenger picks VDF challenge 
let unsolved_vdf = SetupForVDF::pick_challenge(&setup); 
// 2. challenger sends unsolved_vdf to solver
// 3. solver solves VDF
let solved_vdf = UnsolvedVDF::eval(&unsolved_vdf);
// 4. solver sends solved vdf to challenger 
// 5. challnger checks solution
let res = solved_vdf.verify(&unsolved_vdf);
assert!(res.is_ok())

    Define H_G as part of public setup

    To be aligned with the paper the public setup must also define H_G (hash to group). A way to do it will be to pick at random domain separator to be used with the existing H_G such that the new H_G (H_G') will be specific to a given pubic setup

    I conducted some simple measurements as part of the test in lib. Benchmarks should help picking the right parameters for the VDF. specifically t for required time delay. There are several other constants that are worth to explore.

    relevant statistics to measure is mean and std
