Struct bls_like::pop::BitPoPSignedMessage

pub struct BitPoPSignedMessage<E: EngineBLS, POP: ProofsOfPossession<E>> { /* fields omitted */ }

One individual message with attached aggreggate BLS signatures from signers for whom we previously checked proofs-of-possession, and with the singers presented as a compact bitfield.

We may aggregage only one signatures per signer here, but our serialized signature is only one 96 or or 48 bytes compressed curve point, plus the ProofsOfPossession::Signers, which takes about 1 bit per signer if optimized correctly.

You must provide a ProofsOfPossession for this, likely by implementing it for your own data structures.

Methods

impl<E, POP> BitPoPSignedMessage<E, POP> where
    E: EngineBLS,
    POP: ProofsOfPossession<E>, 

pub fn new(
    proofs_of_possession: POP,
    message: Message
) -> BitPoPSignedMessage<E, POP>

pub fn add(&mut self, signed: &SignedMessage<E>) -> Result<(), PoPError>

Include one signed message, after testing for message and proofs-of-possession table agreement, and disjoint publickeys.

pub fn merge(
    &mut self,
    other: &BitPoPSignedMessage<E, POP>
) -> Result<(), PoPError>

Merge two BitPoPSignedMessage, after testing for message and proofs-of-possession table agreement, and disjoint publickeys.

Trait Implementations

impl<'a, E, POP> Signed for &'a BitPoPSignedMessage<E, POP> where
    E: EngineBLS,
    POP: ProofsOfPossession<E>, 

type E = E

type M = Message

type PKnM = Once<(Message, PublicKey<E>)>

Iterator over messages and public key reference pairs.

fn messages_and_publickeys(self) -> Self::PKnM

Returns an iterator over messages and public key reference for pairings, often only partially aggregated.
