Function zk_pass::chaum_pedersen::test::test_execute_protocol

pub fn test_execute_protocol<T>(
    params: &T::GroupParameters,
    x: &T::Secret
) -> boolwhere
    T: ChaumPedersen,

Executes the Chaum-Pedersen protocol using a generic implementation.

This function demonstrates a typical execution flow of the Chaum-Pedersen cryptographic protocol. It encapsulates the roles of both the client and the server, illustrating the generation of commitment, challenge, response, and the verification process.

The function is generic over a type T that implements the ChaumPedersen trait, allowing it to work with any specific cryptographic scheme that conforms to the protocol.

Arguments

• params - Reference to the group parameters. These parameters are essential for the cryptographic operations and depend on the specific implementation of the Chaum-Pedersen protocol.
• x - Reference to the secret value. This is the secret that the client wants to prove knowledge of without revealing it.

Type Parameters

• T - A type that implements the ChaumPedersen trait. This type dictates the specifics of the cryptographic operations used in the protocol.

Returns

Returns a boolean indicating whether the verification was successful. A value of true means that the client successfully proved knowledge of the secret without revealing it, while false indicates a failure in the protocol execution.

Example

// Assume `DiscreteLogChaumPedersen` implements `ChaumPedersen`.
use zk_pass::chaum_pedersen::test::test_execute_protocol;
use zk_pass::chaum_pedersen::discretelog::DiscreteLogChaumPedersen;
use zk_pass::chaum_pedersen::constants::RFC5114_MODP_2048_256_BIT_PARAMS;
use rand::rngs::OsRng;
use num_bigint::RandBigInt;

let params = RFC5114_MODP_2048_256_BIT_PARAMS.to_owned();
let mut rng = OsRng;
let secret = rng.gen_biguint_below(&params.p);

let result = test_execute_protocol::<DiscreteLogChaumPedersen>(&params, &secret);
assert_eq!(result, true);
