Struct ocelot::oprf::kmprt::Receiver

pub struct Receiver<OPRF: OprfReceiver + SemiHonest> { /* private fields */ }

KMPRT oblivious programmable PRF receiver.

This implements the hashing-based OPPRF receiver in Figure 7 of the paper. It uses the table-based one-time OPPRF under-the-hood (Figure 6 of the paper), which itself uses an OPRF.

Implementations

impl<OPRF: OprfReceiver<Seed = Block512, Input = Block, Output = Block512> + SemiHonest> Receiver<OPRF>

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

where C: AbstractChannel, RNG: CryptoRng + Rng,

Initialize the OPPRF receiver.

pub fn receive<C, RNG>( &mut self, channel: &mut C, inputs: &[Block], rng: &mut RNG ) -> Result<Vec<Block512>, Error>

where C: AbstractChannel, RNG: CryptoRng + Rng,

Run the OPPRF on inputs provided by the inputs slice.
