Struct ClientKey 

pub struct ClientKey { /* private fields */ }

A structure containing the client key, which must be kept secret.

In more details, it contains:

• lwe_secret_key - an LWE secret key, used to encrypt the inputs and decrypt the outputs. This secret key is also used in the generation of bootstrapping and key switching keys.
• glwe_secret_key - a GLWE secret key, used to generate the bootstrapping keys and key switching keys.
• parameters - the cryptographic parameter set.

Implementations

impl ClientKey

pub fn encrypt(&self, message: bool) -> Ciphertext

Encrypts a Boolean message using the client key.

Example

use concrete_boolean::prelude::*;

// Generate the client key and the server key:
let (cks, mut sks) = gen_keys();

// Encryption of one message:
let ct = cks.encrypt(true);

// Decryption:
let dec = cks.decrypt(&ct);
assert_eq!(true, dec);

pub fn decrypt(&self, ct: &Ciphertext) -> bool

Decrypts a ciphertext encrypting a Boolean message using the client key.

Example

use concrete_boolean::prelude::*;

// Generate the client key and the server key:
let (cks, mut sks) = gen_keys();

// Encryption of one message:
let ct = cks.encrypt(true);

// Decryption:
let dec = cks.decrypt(&ct);
assert_eq!(true, dec);

pub fn new(parameter_set: &BooleanParameters) -> ClientKey

Allocates and generates a client key.

Panic

This will panic when the “cuda” feature is enabled and the parameters uses a GlweDimension > 1 (as it is not yet supported by the cuda backend).

Example

use concrete_boolean::client_key::ClientKey;
use concrete_boolean::parameters::TFHE_LIB_PARAMETERS;
use concrete_boolean::prelude::*;

// Generate the client key:
let cks = ClientKey::new(&TFHE_LIB_PARAMETERS);

Trait Implementations

impl Clone for ClientKey

fn clone(&self) -> ClientKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClientKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClientKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ClientKey

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ClientKey

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
