<p>PCT No. PCT/FR96/01524 Sec. 371 Date Mar. 26, 1998 Sec. 102(e) Date Mar. 26, 1998 PCT Filed Oct. 1, 1996 PCT Pub. No. WO97/14119 PCT Pub. Date Apr. 17, 1997An authentication method for a wired-logic microcircuit mounted on a support and a microcircuit reading terminal. The microcircuit is provided with a memory which has data readable by the terminal. A secret code of the microcircuit is arranged in a region of the memory that is not readable by the terminal. The microcircuit generates an authentication code from the data in the memory that is readable by the terminal, the secret code and a random code. The terminal generates an authentication code from the data in the microcircuit memory that is readable by the terminal, a secret code provided to the terminal by a microcircuit user and random code, and the authentication code generated by the microcircuit is compared with the authentication code generated by the terminal.</p> |
