Trait Implementations

source

impl Associable<PaillierPK> for PaillierCiphertext

source

fn associate(self, public_key: &PK) -> AssociatedCiphertext<'_, Self, PK>

‘Enriches’ a ciphertext by associating it with a corresponding public key. This allows to overlead operators for homomorphic operations.

source

impl Debug for PaillierPK

source

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

Formats the value using the given formatter. Read more

source

impl DecryptionKey<PaillierPK> for PaillierSK

source

fn decrypt_raw(
    &self,
    public_key: &PaillierPK,
    ciphertext: &PaillierCiphertext
) -> Integer

Decrypts a rich Paillier ciphertext using the secret key.

println!("The decrypted message is {}", secret_key.decrypt(&ciphertext));
// Prints: "The decrypted message is 5".

source

fn decrypt(
&self,
ciphertext: &AssociatedCiphertext<'pk, <PK as EncryptionKey>::Ciphertext, PK>
) -> <PK as EncryptionKey>::Plaintext

Decrypt the associated ciphertext using the secret key.

source

impl EncryptionKey for PaillierPK

source

fn encrypt_raw<R>(
 &self,
 plaintext: &Integer,
 rng: &mut GeneralRng<R>
) -> PaillierCiphertext where
 R: SecureRng,

Encrypts a plaintext integer using the Paillier public key.

let ciphertext = public_key.encrypt(&Integer::from(5), &mut rng);

type Input = Integer

Input is the type used to multiply additive ciphertexts or exponentiate multiplicative ciphertexts.

type Plaintext = Integer

The type of the plaintext to be encrypted.

type Ciphertext = PaillierCiphertext

The type of an encrypted plaintext, i.e. a ciphertext.

source

fn encrypt<R>(
 &'pk self,
 plaintext: &Self::Plaintext,
 rng: &mut GeneralRng<R>
) -> AssociatedCiphertext<'pk, Self::Ciphertext, Self> where
 R: SecureRng,

Encrypt the plaintext using the public key and a cryptographic RNG and immediately associate it with the public key.

source

fn add(
 &self,
 ciphertext_a: <PaillierPK as EncryptionKey>::Ciphertext,
 ciphertext_b: <PaillierPK as EncryptionKey>::Ciphertext

Combines two ciphertexts so that their decrypted value reflects some addition operation

source

fn mul(
 &self,
 ciphertext: <PaillierPK as EncryptionKey>::Ciphertext,
 input: <PaillierPK as EncryptionKey>::Input
) -> <PaillierPK as EncryptionKey>::Ciphertext

Applies some operation on a ciphertext so that the decrypted value reflects some multiplication with input

source
