摘要： A cryptographic processing unit divides and inputs constituent bits of data to be subjected to data processing to lines, and repeatedly performs a data converting operation using round functions on the data of the respective lines. The cryptographic processing unit inputs n/d-bit data obtained by dividing n-bit data as input data by a division number d to each line, and repeatedly performs a round calculation including a data converting operation using round functions. The n/d-bit data in each line having output data of the round calculations is divided into d/2 sets of data, and the divided data are combined to restructure d sets of n/d-bit data that are different from the output data of the round calculations of the previous stage. The restructured data is set as input data for round calculations of the next stage. The cryptographic processing realizes improved diffusion properties and a high level of security.
