ABSTRACT:
Cyclic-redundancy-check (CRC) processing is executed on data blocks each having a predetermined data amount, thereby calculating respective CRC values for the data blocks. Furthermore, CRC processing is executed on the respective CRC values a number of times determined according to random numbers that are generated sequentially, thereby generating sig values to be attached respectively to next data blocks.
