Struct ocelot::oprf::kkrt::Sender

pub struct Sender<OT: OtReceiver + SemiHonest> { /* private fields */ }

KKRT oblivious PRF sender.

Implementations

impl<OT: OtReceiver<Msg = Block> + SemiHonest> Sender<OT>

pub fn encode( &self, input: <Sender<OT> as ObliviousPrf>::Input, output: &mut <Sender<OT> as ObliviousPrf>::Output )

Encode input into output. This is not the same as the compute method as it does not integrate the OPRF seed. However, it is useful for optimization purposes (e.g., when the same seed is used on multiple encoded inputs).

Trait Implementations

impl<OT: OtReceiver<Msg = Block> + SemiHonest> ObliviousPrf for Sender<OT>

type Seed = Block512

PRF seed.

type Input = Block

PRF input.

type Output = Block512

PRF output.

impl<OT: OtReceiver<Msg = Block> + SemiHonest> Sender for Sender<OT>

fn init<C, RNG>(channel: &mut C, rng: &mut RNG) -> Result<Self, Error>

where C: AbstractChannel, RNG: CryptoRng + Rng,

Runs any one-time initialization.

fn send<C, RNG>( &mut self, channel: &mut C, m: usize, _: &mut RNG ) -> Result<Vec<Self::Seed>, Error>

where C: AbstractChannel, RNG: CryptoRng + Rng,

Runs m OPRF instances as the sender, returning the OPRF seeds.

fn compute(&self, seed: Self::Seed, input: Self::Input) -> Self::Output

Computes the oblivious PRF on seed seed and input input.
