Pseudo-Hadamard transform
text:
The pseudo-Hadamard transform is a reversible transformation of a bit string that provides cryptographic diffusion. See Hadamard transform. The bit string must be of even length so that it can be split into two bit strings a and b of equal lengths, each of n bits. To compute the transform for Twofish algorithm, a' and b', from these we use the equations: To reverse this, clearly: On the other hand, the transformation for SAFER+ encryption is as follows:
