<p><P>PROBLEM TO BE SOLVED: To provide a positive mutual authentication system which improves the processing efficiency of an apparatus and conforms to International Standards. <P>SOLUTION: Data M1 is data for 16 bytes in a random number Ra generated by a communication partner, and data M2 is data for 16 bytes obtained by excluding the data M1 in the random number Ra. Data M3 is a random number Rb generated by itself. When the data M3 obtained by decoding is determined to be equal to the random number Rb generated by itself and when data M1 obtained corresponding to data C1 is determined to be equal to data M1 obtained corresponding to data C4, the communication partner is authenticated to be a rightful apparatus. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
