Data processing device and method for cryptographic processing of data

Abstract

According to an embodiment, a data processing device is described comprising a deformer configured to deform a first data block in accordance with a first seed, a seed generator configured to generate a sequence of second seeds, wherein the sequence of second seeds comprises the first seed, a cryptographic processor configured to receive the deformed first data block and, for each second seed, to deform the deformed first data block in accordance with the second seed, to generate a sequence of second data blocks and to cryptographically process each second data block of the sequence of second data blocks to generate a sequence of processed data blocks and an extractor configured to extract a result of the cryptographic processing of the first data block from the sequence of processed data blocks.
