摘要:
Techniques for protecting memory locations within a stakeholder's engine according to the Multi-Stakeholder Model, and a protocol for remote attestation to a device supporting the Multi-Stakeholder Model that provides extra evidence of the identity of the three actors.
摘要:
A content display apparatus which processes protected information configured, with an aim to prevent access from any unauthorized program, to include: a process managing unit which manages a plurality of processes operable in the content display apparatus; and an access detecting unit configured to detect access to the protected-information access detecting unit which detects access to the protected information. The process managing unit includes an application execution control unit which temporarily stops the operation of each of at least one process other than a process which accesses the protected information among the plurality of processes when the access to the protected information is detected by the protected-information access detecting unit.
摘要:
A device (110) according to an implementation of the present invention, having a plurality of virtual machines (1002, 1003, 1004, and 1005), includes a virtualization software (1001) which manages the virtual machines. The virtualization software includes an application VM creating unit (1300) which creates a virtual machine for executing a program. A first virtual machine (1002) determines whether a first program is to be executed on the first virtual machine or to be executed on a virtual machine other than the first virtual machine. When the first virtual machine determines that the first program is to be executed on the other virtual machine, the application VM creating unit creates a second virtual machine for executing the first program.
摘要:
A method to allow a device to boot in a secure fashion, even though some of the components within the secure device's firmware may be not present, not authorised, or not correctly operating.
摘要:
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.
摘要:
A method for executing a predetermined software component which is verifiable against integrity measurements, the method including (i) providing a first mapping from logical identifiers to software component enabled status flags, (ii) providing a second mapping from the logical identifiers and previous software component statuses information to actual integrity measurement certificates containing verification data, (iii) looking up the first mapping for a given logical identifier identifying the predetermined software component to get a status flag indicating whether the predetermined software component is enabled, (iv) if the status flag indicates that the predetermined software component is not enabled, updating a current integrity measurement stored within a disabled integrity measurement certificate, and (v) if the status flag indicates that the predetermined software component is enabled and verification of the predetermined software component is successful, updating a current integrity measurement stored within an integrity measurement certificate.
摘要:
An information processing device includes an external connection unit which connects to an external device; and a communication control unit which obtains data from a first virtual machine, transmits the data to a second virtual machine, and transmits, to the external connection unit, transmission completion information indicating that the data is already transmitted to the second virtual machine. The external connection unit (i) determines, based on the transmission completion information, whether or not a virtual machine is the second virtual machine to which the data is already transmitted, when the external connection unit receives, from the virtual machine, a request for a connection to the external device, and (ii) permits a connection between the virtual machine and the external device, when the external connection unit determines that the virtual machine is not the second virtual machine to which the data is already transmitted.
摘要:
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. The information processing apparatus is provided with a linkage certificate that contains a first configuration comparison value, which indicates a cumulative hash value of the first module group to be started up by secure boot, and a module measurement value, which indicates a hash value of the first module of the second module group to be started up by secure boot. After the secure boot of the first module group, it is verified that the first module group has been started up by comparison with the first configuration comparison value.
摘要:
For the keys in a key tree group composed of root keys for each of multiple stakeholders, a shared key is generated between the multiple stakeholders, and access restrictions with respect to the generated shared key are flexibly set. A shared key control unit and a tamper-resistant module are provided for each of the multiple stakeholders. The shared key is set based on stakeholder dependency relationships. After the shared key is set, access to the shared key is controlled so that access is not possible by malicious stakeholders, so as to maintain the security level.
