Abstract
Data blocks of an input data unit may be received in parallel as a data segment on a data bus. For each received data segment, tweak values corresponding to the data blocks may be generated using a key and an input vector. The data blocks may be encrypted using parallel encryption circuitry blocks, based on a symmetric block cipher that uses another key and one of the tweak values. The encrypted data blocks may be combined into an output data unit.
