classmethod random_permutation(number_of_passes, message_size)

Generate a random Permutations object

Parameters:

• number_of_passes (int) – Total number of iterations

• message_size (int) – Size of the message for which to calculate the parity strategy

Return type:

Permutations

shorten_pass(pass_idx, max_length)

In some protocols, the message length decreases, this function adjusts the permutations accordingly, by discarding large indices.

Parameters:

• pass_idx (int) – Index of the permutation to shorten

• max_length (int) – New message length, and maximum of the entries in

• permutation (the) –

Return type:

None
