Filed: 2003-04-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide an enciphering and deciphering system having high cipher strength while suppressing a processing burden.  <P>SOLUTION: A password obtained by adding one additional character generated from a file size following a password recognized by a user or the like is taken as a password on processing (steps S11 to S13). A numerical series Y having a sufficiently long period is generated. A preceding enciphered output value directly before it and the numerical series Y are used to generate a numerical series X (step S15). The numerical series X are used to convert characters Pj constituting the password to characters Qj selected from a number of kinds of characters, and the characters Qj are taken as a deciphering key for a one-byte portion of data to be enciphered (step S16). XOR (exclusive OR) between the enciphering key and data of one byte of data to be enciphered is operated to perform enciphering (step S17). Similar processing is performed for deciphering. Since the size of data is not changed at the time of enciphering, the additional character is equal to that at the time of enciphering. Consequently, in the enciphering and deciphering method, a processing load is not so heavy and reliability is high.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
