Struct PublicKey

pub struct PublicKey {
    pub w: G2Projective,
    pub x: G2Projective,
    pub y: Vec<G2Projective>,
    pub y_blinds: Vec<G1Projective>,
}

The public key contains a generator point for each message that is signed and two extra. See section 4.2 in https://eprint.iacr.org/2015/525.pdf and https://eprint.iacr.org/2017/1197.pdf

w corresponds to m’ in the paper to achieve EUF-CMA security level.

Fields

w: G2Projective

The secret for m’

x: G2Projective

The blinding secret

y: Vec<G2Projective>

The secrets for each signed message

y_blinds: Vec<G1Projective>

The secrets for each signed message for blinding purposes

Implementations

impl PublicKey

pub fn is_valid(&self) -> Choice

Check if this public key is valid

pub fn is_invalid(&self) -> Choice

Check if this public key is invalid

pub fn to_bytes(&self) -> Vec<u8>

Store the public key as a sequence of bytes Each scalar is compressed to big-endian format Needs (N + 2) * P space otherwise it will panic where N is the number of messages that can be signed

pub fn from_bytes<B: AsRef<[u8]>>(bytes: B) -> Option<Self>

Convert a byte sequence into the public key

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl Default for PublicKey

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PublicKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&PublicKey> for Vec<u8>

fn from(pk: &PublicKey) -> Self

Converts to this type from the input type.

impl From<&SecretKey> for PublicKey

fn from(sk: &SecretKey) -> Self

Converts to this type from the input type.

impl From<PublicKey> for Vec<u8>

fn from(pk: PublicKey) -> Self

Converts to this type from the input type.

impl PartialEq for PublicKey

fn eq(&self, other: &PublicKey) -> 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.

impl PublicKey for PublicKey

type MessageGenerator = G2Projective

The generator type used for signing messages and creating proofs of message knowledge

type BlindMessageGenerator = G1Projective

The generator type used for creating blind signatures

fn to_bytes(&self) -> Vec<u8>

Serialize the public key to bytes

impl Serialize for PublicKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
