Member Function Documentation

ReEncrypt()

template<class Element >

Ciphertext<Element> lbcrypto::LPAlgorithmPRENull< Element >::ReEncrypt ( const LPEvalKey< Element >  evalKey, ConstCiphertext< Element >  ciphertext, const LPPublicKey< Element >  publicKey = nullptr  ) const

inlinevirtual

Function to define the interface for re-encypting ciphertext using the array generated by ProxyGen

Parameters

&evalKey	the evaluation key.
&ciphertext	the input ciphertext.
publicKey	the public key of the recipient of the re-encrypted ciphertext.
*newCiphertext	the new ciphertext.

Implements lbcrypto::LPPREAlgorithm< Element >.

ReKeyGen()

template<class Element >

LPEvalKey<Element> lbcrypto::LPAlgorithmPRENull< Element >::ReKeyGen ( const LPPublicKey< Element >  newPrivateKey, const LPPrivateKey< Element >  origPrivateKey  ) const

inlinevirtual

Function to generate 1..log(q) encryptions for each bit of the original private key Variant that uses the public key for the new secret key.

Parameters

&newPrivateKey	encryption key for the new ciphertext.
&origPrivateKey	original private key used for decryption.
&ddg	discrete Gaussian generator.
*evalKey	the evaluation key.

Implements lbcrypto::LPPREAlgorithm< Element >.
