Implementations§

source§

impl<P> PublicKey<P>
where P: Pairing,

source

pub fn from_secret(sk: &SecretKey<P>) -> PublicKey<P>

Derived from a secret key sk by exponentiating the generator of G2 with sk.

For now, the generator used is the default generator of the underlying library however, this should be parametrized in the future

source

pub fn verify(&self, m: &[u8], signature: Signature<P>) -> bool

Verifies a single message and signature pair using this PublicKey by checking that pairing(sig, g_2) == pairing(g1_hash(m), public_key) where g_2 is the generator of G2.

For now, the generator used is the default generator of the underlying library however, this should be parametrized in the future

source

pub fn check_proof( &self, ro: &mut RandomOracle, proof: &SigmaProof<Response<<P as Pairing>::G2>> ) -> bool

Check proof of knowledge of the secret key with respect to the public key and the challenge which is given in terms of a random oracle.
