Struct PublicKeyPoP 

pub struct PublicKeyPoP(/* private fields */);

A public key with its proof of possession.

Implementations

impl PublicKeyPoP

pub fn verify(&self) -> Result<PublicKey, AtmsError>

Verify the proof of possession with respect to the associated public key, by checking that $e(pk, H_2(b“PoP“)) = e(G_1, \texttt{self})$, where self is the proof of possession.

Error

Returns InvalidPoP in case the proof is invalid.

Example

let sk = SigningKey::gen(&mut OsRng);
let pkpop = PublicKeyPoP::from(&sk);
assert!(pkpop.verify().is_ok());

pub fn to_bytes(&self) -> [u8; 144]

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, AtmsError>

Deserialise a byte string to a PublicKeyPoP.
