Abstract

PROBLEM TO BE SOLVED: To compensate the balance of the IC card 11 containing electronic coins in case of its breakage. SOLUTION: The card 11 and a compensation institution 13 share secret information; when coin information Mi+1 is generated in the card 11 as a result of payment, last disturbance information hMi-1Mi, and Mi+1 and S are inputted to a unidirectional function arithmetic part 14 to obtain disturbance information hMiMi+1, which is recorded in a recording part 16 of a personal computer together with Mi+1 and also stored in the storage part 12 of the card 11. If the card 11 is broken, the information in the recording part 16 is all supplied to the institution 13, which inputs Mi+1, hMi-1Mi, and S to a unidirectional function arithmetic part 24 in order according to the old information; and its output h(hMi-1Mi, Mi+1, S) and compared with the inputted hMiMi+1 and when they completely match each other, the amount of money determined by from M1 to Mi+1 is compensated.

When the IC card 11 is destroyed, all the information recorded on the external recording medium 16 is brought into the IC card compensating engine device 13 to receive compensation for the use information.
If the usage information M is an electronic coin as described above, I
The C card compensation institution device 13 is a device of a financial institution such as a bank, and all information brought in from the external recording medium 16 is temporarily stored in the buffer 21. A set of each use information M and corresponding disturbance information in the information in the buffer 21 is taken out in an old order. That is, in the example shown in FIG.
1 is stored, and its hM1 is stored in the register 22.
M1 and the shared secret information S in the storage unit 23 are input to the disturbance unit 24, and in this example, a one-way function operation is performed on the combination of M1 and S to obtain h (M1, S). This h (M
1, S) and hM1 in the register 22 are compared by the comparing unit 25, and if they match, the next set of information M2, hM1, and M2 is extracted from the buffer 21, and M2 is sent to the disturbance unit 24 and hM1
1 and M2 are supplied to the register 22, respectively. At this time, the information hM1 immediately before in the register 22 is transferred to the disturbance unit 24.
