Abstract:
1. An authentication system comprising: an authentication device; and an information processing device that is for executing an application program, the application program being subject to authentication processing performed with the authentication device, wherein the information processing device includes: wherein the first condition is a condition that integrity of a plurality of system programs executed in secure boot is maintained after the secure boot, the secure boot is a processing of sequentially executing the system programs from a start of boot to completion of the boot while verifying the integrity thereof, wherein the authentication device includes: wherein the first authentication processing unit acquires the encrypted authentication key and writes the encrypted authentication key into the key information holding unit, wherein the decryption processing unit decrypts the encrypted second decryption key using the first decryption key to obtain the second decryption key after the encrypted authentication key is written into the key information holding unit, decrypts the encrypted authentication key using the second decryption key to obtain the authentication key only when the first condition is satisfied, and outputs the authentication key only when a second condition is satisfied, the second condition indicating a condition for outputting the authentication key after decryption of the encrypted authentication key, wherein the second condition is a condition that integrity of the application program is maintained, wherein the first authentication processing unit performs second authentication processing with the authentication device using the authentication key, when the authentication key is output by the decryption processing unit, and wherein the second authentication processing unit performs the second authentication processing with the information processing device using the authentication key, after the authentication key is transmitted by the transmission unit.
