ABSTRACT:
A method of encrypting a data unit, the method comprising the steps of dividing the data unit into a series of data blocks, and for each data block, applying a block cipher function to a data block counter value to generate an encrypted block counter value, performing a logical operation to combine the encrypted block counter with the data block, and applying a block cipher function to the combined data.
