Public Functions

RLWECiphertextImpl() = default

inline explicit RLWECiphertextImpl(const std::vector<NativePoly> &elements)

Constructs an RLWE ciphertext from its ring elements

Parameters

elements – the RLWE pair (a, b) as a vector of two ring elements, elements[0] = a and elements[1] = b, where b = a * s + e + encoded message for the RLWE secret key s

inline explicit RLWECiphertextImpl(std::vector<NativePoly> &&elements) noexcept

Constructs an RLWE ciphertext from its ring elements, moving them

Parameters

elements – the RLWE pair (a, b) as a vector of two ring elements, elements[0] = a and elements[1] = b, where b = a * s + e + encoded message for the RLWE secret key s

inline RLWECiphertextImpl(const RLWECiphertextImpl &rhs)

inline RLWECiphertextImpl(RLWECiphertextImpl &&rhs) noexcept

inline RLWECiphertextImpl &operator=(const RLWECiphertextImpl &rhs)

inline RLWECiphertextImpl &operator=(RLWECiphertextImpl &&rhs) noexcept

inline const std::vector<NativePoly> &GetElements() const

inline std::vector<NativePoly> &GetElements()

inline void SetFormat(const Format format)

Switches all ring elements between COEFFICIENT and EVALUATION representation using NTT

Parameters

format – the representation to switch the ring elements to

inline bool operator==(const RLWECiphertextImpl &other) const

Parameters

other – the RLWE ciphertext to compare with

Returns

true if both ciphertexts have equal ring elements

inline bool operator!=(const RLWECiphertextImpl &other) const

Parameters

other – the RLWE ciphertext to compare with

Returns

true if the ring elements differ

inline void save(Archive &ar, std::uint32_t const version) const

template<class Archive>
inline void load(Archive &ar, std::uint32_t const version)

inline virtual std::string SerializedObjectName() const override

Returns the name identifying the derived class in serialized form; every serializable class provides it.

Returns

the serialized object name
