ABSTRACT:
A method and apparatus for inter-round mixing in iterated block substitution systems is disclosed. The method involves optimizing inter-round mixing so that each sub-block of data affects each other in the same way. This is accomplished by applying a quick trickle permutation or a quasi quick trickle permutation to blocks of data allocated to n individual substitution boxes.
