Struct mithril_stm::multi_sig::VerificationKeyPoP

pub struct VerificationKeyPoP {
    pub vk: VerificationKey,
    pub pop: ProofOfPossession,
}

MultiSig public key, contains the verification key and the proof of possession.

Fields

vk: VerificationKey

The verification key.

pop: ProofOfPossession

Proof of Possession.

Implementations

impl VerificationKeyPoP

pub fn check(&self) -> Result<(), MultiSignatureError>

if e(k1,g2) = e(H_G1("PoP" || mvk),mvk) and e(g1,mvk) = e(k2,g2) are both true, return 1. The first part is a signature verification of message “PoP”, while the second we need to compute the pairing manually.

pub fn to_bytes(self) -> [u8; 192]

Convert to a 144 byte string.

Layout

The layout of a PublicKeyPoP encoding is

• Public key
• Proof of Possession

pub fn from_bytes(bytes: &[u8]) -> Result<Self, MultiSignatureError>

Deserialize a byte string to a PublicKeyPoP.

Trait Implementations

impl Clone for VerificationKeyPoP

fn clone(&self) -> VerificationKeyPoP

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VerificationKeyPoP

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VerificationKeyPoP

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&SigningKey> for VerificationKeyPoP

fn from(sk: &SigningKey) -> Self

Convert a secret key into a VerificationKeyPoP by simply converting to a MspMvk and MspPoP.

impl PartialEq for VerificationKeyPoP

fn eq(&self, other: &VerificationKeyPoP) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for VerificationKeyPoP

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
