IPC: G09C1/00
Filed: 2003-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide an encryption processing device and an encryption processing method for realizing an advanced decryption difficulty in encryption processing.  <P>SOLUTION: The encryption processing device is so constituted that the whole or a part of a plaintext to be inputted is inputted into an arithmetic processing section to perform arithmetic processing, the plaintext summary value is obtained by calculating checksum, MAC (message authentication code), MDC (message digest code), CRC (cyclic redundancy check) etc., and the value is applied as an initial value or intermediate data to carry out encryption processing together with each block. Also, the summary value of random numbers and the inputted plaintext and a hash value based on the intrinsic value such as an address corresponding to the inputted plaintext block are calculated, and the hash value is applied to carry out encryption processing together with each block. Thus, even when the input block contains the same address or the same data, the output can be made different and the encryption processing with enhanced safety can be realized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Calibration of a frequency deviation of the internal clock may be performed by counting a clock pulse extracted from a carrier wave of the standard wave as long as a prescribed period and determining the counted number of the internal clock counted in the same period. In addition, the calibration of the internal clock may be performed by utilizing the carrier wave of the standard wave as a reference clock of a PLL circuit.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
