Public Functions

inline virtual ~MultipartyCKKSRNS()
virtual DecryptResult MultipartyDecryptFusion(const std::vector<Ciphertext<DCRTPoly>> &ciphertextVec, Poly *plaintext) const override

Threshold FHE: Method for combining the partially decrypted ciphertexts and getting the final decryption in the clear as a Poly.

Parameters

  • &ciphertextVec – vector of “partial” decryptions.

  • *plaintext – the plaintext output as a Poly.

Returns

the decoding result.
