Public Functions

virtual ~PKERNS() = default
Ciphertext<DCRTPoly> Encrypt(DCRTPoly plaintext, const PublicKey<DCRTPoly> publicKey) const override

Method for encrypting plaintext using LBC

Parameters

  • &publicKey – public key used for encryption.

  • plaintext – copy of the plaintext element. NOTE a copy is passed! That is NOT an error!

  • doEncryption – encrypts if true, embeds (encodes) the plaintext into cryptocontext if false

  • *ciphertext – ciphertext which results from encryption.

Ciphertext<DCRTPoly> Encrypt(DCRTPoly plaintext, const PrivateKey<DCRTPoly> privateKey) const override

Method for encrypting plaintex using LBC

Parameters

  • privateKey – private key used for encryption.

  • plaintext – copy of the plaintext input. NOTE a copy is passed! That is NOT an error!

  • doEncryption – encrypts if true, embeds (encodes) the plaintext into cryptocontext if false

  • *ciphertext – ciphertext which results from encryption.

virtual DecryptResult Decrypt(ConstCiphertext<DCRTPoly> ciphertext, const PrivateKey<DCRTPoly> privateKey, NativePoly *plaintext) const override

Method for decrypting plaintext using LBC

Parameters

  • &privateKey – private key used for decryption.

  • &ciphertext – ciphertext id decrypted.

  • *plaintext – the plaintext output.

Returns

the decoding result.

virtual DecryptResult Decrypt(ConstCiphertext<DCRTPoly> ciphertext, const PrivateKey<DCRTPoly> privateKey, Poly *plaintext) const override

Method for decrypting plaintext using LBC

Parameters

  • &privateKey – private key used for decryption.

  • &ciphertext – ciphertext id decrypted.

  • *plaintext – the plaintext output.

Returns

the decoding result.
