Class for performing data permutations.

Module Contents

class secure_learning.utils.data_permutator.SecureDataPermutator(secure_permutations: bool, seed: int | None = None)

Class for performing data permutations.

Parameters:

• secure_permutations – If True, perform permutations collaboratively using a secure permutation protocol. If False perform local permutations based on a shared random seed

• seed – Set the random seed. A shared seed can be generated using the refresh_seed method

permute_data: Callable[[tno.mpc.mpyc.secure_learning.utils.types.SeqMatrix[tno.mpc.mpyc.secure_learning.utils.types.SecNumTypesTV]], tno.mpc.mpyc.secure_learning.utils.types.Matrix[tno.mpc.mpyc.secure_learning.utils.types.SecNumTypesTV]]

property seed: int

Seed used for randomness.

Raises:

SecureLearnValueError – Seed has not been set

Returns:

Seed used for randomness

async refresh_seed() → None

Generate common seed for future permutations.

static secure_data_permutation(matrix: tno.mpc.mpyc.secure_learning.utils.types.SeqMatrix[tno.mpc.mpyc.secure_learning.utils.types.SecNumTypesTV]) → tno.mpc.mpyc.secure_learning.utils.types.Matrix[tno.mpc.mpyc.secure_learning.utils.types.SecNumTypesTV]

Permute the rows of the provided matrix using a secure permutation protocol.

Parameters:

matrix – Matrix to be permuted

Returns:

Matrix with shuffled rows

insecure_data_permutation(matrix: tno.mpc.mpyc.secure_learning.utils.types.SeqMatrix[tno.mpc.mpyc.secure_learning.utils.types.SecNumTypesTV]) → tno.mpc.mpyc.secure_learning.utils.types.Matrix[tno.mpc.mpyc.secure_learning.utils.types.SecNumTypesTV]

Locally permute the rows of the provided matrix based on a shared random seed.

Parameters:

matrix – Matrix to be permuted

Raises:

SecureLearnValueError – Seed has not been set

Returns:

Matrix with shuffled rows
