Trait scicrypt_traits::threshold_cryptosystems::PartialDecryptionKey

pub trait PartialDecryptionKey<PK: EncryptionKey> {
    type DecryptionShare: DecryptionShare<PK>;

    fn partial_decrypt_raw(
        &self, 
        public_key: &PK, 
        ciphertext: &PK::Ciphertext
    ) -> Self::DecryptionShare;

    fn partial_decrypt<'pk>(
        &self, 
        ciphertext: &AssociatedCiphertext<'pk, PK::Ciphertext, PK>
    ) -> Self::DecryptionShare { ... }
}

A partial decryption key partially decrypts ciphertexts to return a decryption share. If enough decryption shares of different keys are combined, they output the correct decryption.

Required Associated Types

type DecryptionShare: DecryptionShare<PK>

The type of the decryption share. If enough decryption shares of different keys are combined, they output the correct decryption.

Required Methods

fn partial_decrypt_raw(
    &self,
    public_key: &PK,
    ciphertext: &PK::Ciphertext
) -> Self::DecryptionShare

Partially decrypts a ciphertext, returning a valid decryption share.

Provided Methods

fn partial_decrypt<'pk>(
    &self,
    ciphertext: &AssociatedCiphertext<'pk, PK::Ciphertext, PK>
) -> Self::DecryptionShare

Partially decrypts a ciphertext, returning a valid decryption share.
