Detailed Description

A class for encoding, encrypting, decoding, and decrypting a CipherMatrix.

Encrypting raw plain data in HE involves two stages: encode and encrypt. Similary, the opposite direction involes decrypt and decode.

This class performs both steps in each direction, encoding and encrypting a plain matrix to a CipherMatrix, and vice versa.

The plain values are represented using boost::numeric::ublas::tensor with element values that are either double or complex.

Constructor & Destructor Documentation

helayers::CipherMatrixEncoder::CipherMatrixEncoder ( HeContext & he )

Constructs a ready to use object.

Parameters

[in] he the underlying context.

tensor< complex< double > > helayers::CipherMatrixEncoder::decryptDecodeComplex ( const CipherMatrix & src ) const

Decrypt and decode a given CipherMatrix to a 3d tensor of complex numbers.

Parameters

[in] src input CipherMatrix

tensor< double > helayers::CipherMatrixEncoder::decryptDecodeDouble ( const CipherMatrix & src ) const

Decrypt and decode a given CipherMatrix to a 3d tensor of double numbers.

Only the real part is retreived.

Parameters

[in] src input CipherMatrix

void helayers::CipherMatrixEncoder::encodeEncrypt	(	CipherMatrix &	res,
		const boost::numeric::ublas::tensor< double > &	vals,
		int	chainIndex = `-1`
	)		const

Encode and encrypt a 3d array of doubles.

Parameters

[out]	res	object to contain encrypted matrix.
[in]	vals	a 3d tensor to encrypt
[in]	chainIndex	optional target chain index

void helayers::CipherMatrixEncoder::encodeEncrypt	(	CipherMatrix &	res,
		const boost::numeric::ublas::tensor< std::complex< double >> &	vals,
