Vorrichtung zur Durchführung eines Blockchiffrierverfahrens |
| 摘要 |
The invention relates to a device for carrying out a block cipher method, comprising a coding/decoding arithmetic unit (3) to which the data stream of word length j</=n is fed for ciphering. The invention is characterised in that said arithmetic unit (3) comprises several coding/decoding elements (5), each forming one stage of an arithmetic pipeline. The stages of said pipeline are configured in such a way that they work independently of each other in different operating modes and with different codes. Together with the other components and data paths which surround the coding/decoding arithmetic unit (3), the inventive device enables up to p data streams to be coded or decoded at the same time. The word length j</=n and operating mode of each data stream can be chosen independently of the others. The architecture of the device also permits different logical data streams to be processed directly one after the other on the physical channels provided by the hardware resources without any conflict.
