TERMINAL EQUIPMENT, TERMINAL EQUIPMENT AUTHENTICATION SYSTEM, AUTHENTICATION INFORMATION GENERATION METHOD FOR TERMINAL EQUIPMENT AND AUTHENTICATION INFORMATION GENERATION PROGRAM FOR TERMINAL EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To prevent camouflage in the authentication of a terminal.;SOLUTION: Not only statistic information such as an ID number or a password generally in use but also dynamic information generated during communication is used in the next connection. An authentication information generator 140 arbitrarily combines dynamic information A(A1, A2 through Al) stored in a dynamic information storage part 120 with static information B(B1, B2 through Bm) stored in a static information storage part 130 to generate authentication information X(X1, X2 through Xn), and an authentication information storage part 150 stores the authentication information. The generation of the authentication information may be repeated by arbitrary number of times.;COPYRIGHT: (C)2015,JPO&INPIT
