| 20090019551 | INFORMATION SECURITY DEVICE AND COUNTER CONTROL METHOD - A method is provided for flexibly setting a shared counter shared by a plurality of security modules sharing a counter in tree structures, while curbing the amount of secure memory used. The shared counter is realized by a first counter group having a tree structure managed by a first secure module and a second counter group having a tree structure managed by a second secure module sharing a node in the tree structure of the first counter group and a node in the tree structure of the second counter group. The method of sharing using tree structures enables flexibly addition, deletion and access restriction setting of modules that use the shared counter. | 01-15-2009 |
| 20090046862 | METHOD AND DEVICE FOR SPEEDING UP KEY USE IN KEY MANAGEMENT SOFTWARE WITH TREE STRUCTURE - In the key management software having a key database with a tree structure, a high-speed data encryption/decryption process is achieved by changing the tree structure without reducing the security strength when deleting or adding a key from/to the tree structure. The key management software | 02-19-2009 |
| 20090271860 | AUTHENTICATOR APPARATUS - An authenticator apparatus which makes it difficult for an unauthorized user to masquerade and enhances safety includes an authenticating information holding unit ( | 10-29-2009 |
| 20090307783 | DATA PROCESSING DEVICE, METHOD, PROGRAM, INTEGRATED CIRCUIT, AND PROGRAM GENERATING DEVICE - A data processing apparatus controls execution of debugging of a program performed by a debugger. The program includes a verification value used for judgment on whether to permit the debugging, and an access control list that shows whether to permit an access to each of parts constituting the program. The data processing apparatus acquires a debugger ID of the debugger from the debugger, and the verification value and the access control list included in the program. The data processing apparatus judges whether to permit the debugging, according to the result of comparison between the debugger ID and the verification value. The data processing apparatus permits an access to a part of the program to be debugged when the access control list shows that the access is permitted. The data processing apparatus does not permit the access to the part when the access control list shows that the access is not permitted. | 12-10-2009 |
| 20090320110 | SECURE BOOT WITH OPTIONAL COMPONENTS METHOD - A method is executed which is for managing the optional trusted components that are active within a device, such that the device itself controls the availability of trusted components. The device includes: a storing unit which stores a plurality of pieces of software and a plurality of certificates; a receiving unit which receives the certificates; and a selecting unit which selects one of the certificates. The device further includes an executing unit which verifies an enabled one of the plurality of pieces of software using the selected and updated one of the certificates. | 12-24-2009 |

| 20100185859 | SOFTWARE UPDATE SYSTEM, MANAGEMENT APPARATUS, RECORDING MEDIUM, AND INTEGRATED CIRCUIT - An update server | 07-22-2010 |
| 20100229168 | DATA PROCESSING DEVICE, DATA PROCESSING METHOD, DATA PROCESSING PROGRAM, RECORDING MEDIUM, AND INTEGRATED CIRCUIT - When notifying virtual machines of a change to shared data, it is impossible to realize power saving for the apparatus if always notifying a virtual machine in the power-saving state. | 09-09-2010 |
| 20100235588 | SHARED INFORMATION DISTRIBUTING DEVICE, HOLDING DEVICE, CERTIFICATE AUTHORITY DEVICE, AND SYSTEM - A distributing device for generating private information correctly even if shared information is destroyed or tampered with. A shared information distributing device for use in a system for managing private information by a secret sharing method, including: segmenting unit that segments private information into a first through an n | 09-16-2010 |
| 20100325628 | INFORMATION PROCESSING DEVICE - A terminal having a plurality of virtual machines in one-to-one correspondence with a plurality of stakeholders is enabled to activate in compliance with the trust dependency relation among the virtual machines and a virtual machine monitor. The terminal includes: the plurality of virtual machines in one-to-one correspondence with the plurality of stakeholders; a plurality of tamper-resistant modules in one-to-one correspondence with the virtual machines, and a management unit controlling the virtual machines and the tamper-resistant modules in mutually related manner. Each virtual machine securely boots with reference to a certificate having a trust dependency with one or other virtual machines. | 12-23-2010 |
| 20110066838 | INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND COMPUTER PROGRAM AND INTEGRATED CIRCUIT FOR THE REALIZATION THEREOF - The present invention provides an information processing apparatus that is capable of continuously performing secure boot between module groups in the case where software of a terminal device consists of module groups provided by a plurality of providers, while keeping independence between the providers.
