ENCRYPTION DEVICE AND OPERATING METHOD OF ENCRYPTION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240356726 titled 'ENCRYPTION DEVICE AND OPERATING METHOD OF ENCRYPTION DEVICE
The encryption device described in the abstract includes an encryption core circuit that performs encryption operations on input data to generate output data, controlled by an encryption controller circuit. The encryption core circuit consists of various components such as a shiftrow circuit, a security circuit, a mixcolumn addition circuit, and a round key addition operation circuit.
- The shiftrow circuit generates shift data by performing a shiftrow operation on the input data.
- The security circuit generates permutation data by performing a permutation operation, including a mixcolumn multiplication operation, on the shift data.
- The mixcolumn addition circuit generates first mid data by performing a mixcolumn addition operation on the permutation data.
- The round key addition operation circuit generates the output data by performing a round key addition operation on the first mid data.
