SXAL/MBAL - MBAL

MBAL

MBAL is an encryption algorithm built using SXAL that can be applied to messages any number of bytes in length (at least 8). It uses two 64-bit extended keys for key whitening on the first 64 bits. The algorithm consists of 9 steps:

  1. Pre-whitening
  2. Fm: An expanded version of SXAL applied to the entire message
  3. SXAL the block consisting of the first 4 and last 4 bytes
  4. Reverse the byte order of the entire message
  5. Fm
  6. Reverse
  7. SXAL the ends
  8. Fm
  9. Post-whitening

MBAL has been shown to be susceptible to both differential cryptanalysis and linear cryptanalysis.
