Struct RandomizedParams

pub struct RandomizedParams<C: Ciphersuite> { /* private fields */ }

Randomized parameters for a signing instance of randomized FROST.

Implementations

impl<C: Ciphersuite> RandomizedParams<C>

Auto-generated by derive_getters::Getters.

pub fn randomizer(&self) -> &Randomizer<C>

The randomizer, also called α

pub fn randomizer_element(&self) -> &<C::Group as Group>::Element

The generator multiplied by the randomizer.

pub fn randomized_verifying_key(&self) -> &VerifyingKey<C>

The randomized group public key. The group public key added to the randomizer element.

impl<C> RandomizedParams<C>

where C: RandomizedCiphersuite,

pub fn new<R: RngCore + CryptoRng>( group_verifying_key: &VerifyingKey<C>, signing_package: &SigningPackage<C>, rng: R, ) -> Result<Self, Error<C>>

Create a new RandomizedParams for the given VerifyingKey and the given participants.

impl<C> RandomizedParams<C>

where C: Ciphersuite,

pub fn from_randomizer( group_verifying_key: &VerifyingKey<C>, randomizer: Randomizer<C>, ) -> Self

Create a new RandomizedParams for the given VerifyingKey and the given participants for the given randomizer. The randomizer MUST be generated uniformly at random! Use RandomizedParams::new() which generates a fresh randomizer, unless your application requires generating a randomizer outside.

Trait Implementations

impl<C: Clone + Ciphersuite> Clone for RandomizedParams<C>

where C::Group: Clone,

fn clone(&self) -> RandomizedParams<C>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C> Debug for RandomizedParams<C>

where C: Ciphersuite,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C: PartialEq + Ciphersuite> PartialEq for RandomizedParams<C>

where C::Group: PartialEq,

fn eq(&self, other: &RandomizedParams<C>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
