cascada.primitives.simeck module

Simeck family of block ciphers.

This implementation is based on simon and simon_rf.

class cascada.primitives.simeck.SimeckRF(**kwargs)[source]

The non-linear part of the round function of Simon.

This corresponds to f(x) = ((x <<< a) & (x <<< b)) ^ (x <<< c), where (a, b, c) = (5, 0, 4).

class cascada.primitives.simeck.XorModelSimeckRF(input_prop)[source]

class cascada.primitives.simeck.RXModelSimeckRF(input_prop)[source]

class cascada.primitives.simeck.SimeckInstance(value)[source]

Represent the available instances of Simeck.

cascada.primitives.simeck.get_Simeck_instance(simeck_instance)[source]: Return an instance of the Simeck family as a Cipher.
