Abstract
A modified implementation of the Kasumi algorithm executes on a 32-bit processor using full 32-bit operations. The implementation comprises a series of four rounds, each round including an intermediate sub-function executed between two executions of an FL sub-function. The intermediate sub-function is functionally equivalent to two consecutive 16-bit FO sub-functions.
