Yasumasa Nakatsugawa; Tadashi Morita - Web page: https://patentgrep.com/patent/US8782749B2 ## CPC - G06F 21/606: {by securing the transmission between two devices or processes} - G06F 21/77: in smart cards - G06F 21/78: to assure secure storage of data (address-based protection against unauthorised use of memory G06F12/14; record carriers for use with machines and with at least a part designed to carry digital markings G06K19/00) - G06F: ELECTRIC DIGITAL DATA PROCESSING (computer systems based on specific computational models G06N) ## Abstract An IC card compatible with a DES scheme and an AES scheme having a security strength different from that of the DES scheme, includes an inhibition information receiving section for receiving inhibition information for inhibiting predetermined manipulation from being performed in a storage region of the IC card using the DES scheme from an issuing device using the AES scheme, an inhibition flag setting section for performing inhibition processing for inhibiting the predetermined manipulation by the inhibition information, a manipulation request receiving section for receiving a manipulation request from a service providing device or the issuing device, and a manipulation executing section for executing the requested manipulation if the requested manipulation does not correspond to the predetermined manipulation inhibited by the inhibition information. ## Claims ### Claim 1 An information processing device, comprising: an inhibition information receiving section for receiving, from an external device, inhibition information generated by the external device for inhibiting a predetermined manipulation from being performed in a storage region of the information processing device using a first encryption scheme but not inhibiting the predetermined manipulation from being performed in the storage region of the information processing device using a second encryption scheme, the first encryption scheme having a security strength lower than that of the second encryption scheme, and the inhibition information being received from the external device according to the second encryption scheme; an inhibition processing section for performing inhibition processing for inhibiting the predetermined manipulation from being performed using the first encryption scheme based on the inhibition information; a manipulation request receiving section for receiving a manipulation request from the external device or from another external device; and a manipulation executing section for executing the requested manipulation if the requested manipulation does not correspond to the predetermined manipulation inhibited from being performed using the first encryption scheme by the inhibition information. ### Claim 2 (depends on 1) The information processing device according to claim 1, wherein: the storage region is divided into a plurality of logical regions respectively available by different operating subjects, and the inhibition information is set by authorization of an operating subject capable of using each of the logical regions so as to inhibit predetermined manipulation from being performed in each of the logical regions using the first encryption scheme. ### Claim 3 (depends on 1) The information processing device according to claim 1, wherein the inhibition information includes information that designates inhibition of format initialization manipulation of the storage region as the predetermined manipulation. ### Claim 4 (depends on 1) The information processing device according to claim 1, wherein the inhibition information includes information that designates inhibition of addition of service information to the storage region as the predetermined manipulation. ### Claim 5 An information processing method which is carried out using an information processing device, the method comprising: receiving, from an external device, inhibition information generated by the external device for inhibiting a predetermined manipulation from being performed in a storage region of the information processing device using a first encryption scheme but not inhibiting the predetermined manipulation from being performed in the storage region of the information processing device using a second encryption scheme, the first encryption scheme having a security strength lower than that of the second encryption scheme, and the inhibition information being received from the external device according to the second encryption scheme; performing inhibition processing for inhibiting the predetermined manipulation from being performed using the first encryption scheme based on the inhibition information; receiving a manipulation request from the external device or from another external device; and executing the requested manipulation if the requested manipulation does not correspond to the predetermined manipulation inhibited from being performed using the first encryption scheme by the inhibition information. ### Claim 6 (depends on 5) A non-transitory computer-readable recording medium having recorded therein a computer program for causing a computer to execute the information processing method of claim 5.
