ABSTRACT:
An encryption system includes a plurality of encryption operations including individual encryption operations and group encryption operations available for application in the encryption of data. The plurality of encryption operations are selected from the group consisting of functional variance, functional alignment, mathematical offset, wide XOR function, short logical rotation, long logical rotation, functional order, and address encryption. The system includes at least one round of encryption composed of a first encryption operation and a second encryption operation. The first encryption operation is selected from the plurality of encryption operations acting upon input data to generate a first encrypted data set. The second encryption operation is selected from the plurality of encryption operations acting upon the first encrypted data set to generate a second encrypted data set. The first encryption operation and the second encryption operation are different.
