Abstract

A confusion data generator for the generation of non-linear confusion data utilizes a plurality of arrays acting as non-linear state machines to generate a stream of confusion data of a certain width. Each non-linear state machine contributes equally to the overall width of the confusion data. The output bit stream from the confusion data generator is then used with a combiner such as an XOR combiner to generate secure text from plaintext. The confusion data generator can be used to securely store data on a storage medium or transmit data over a communication medium. The confusion data generator is computationally inexpensive, scalable and provides good security when used with a combiner, such as an XOR combiner, to generate secure text.
