摘要： 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 nth pieces of shared information; first distribution unit that distributes the n pieces of shared information to n holding devices on a one-to-one basis; and second distribution unit that distributes the n pieces of shared information to the n holding devices so that each holding device holds an ith piece of shared information distributed by the first distribution unit, as well as a pieces of shared information being different from the ith piece of shared information in ordinal position among n pieces of shared information, “i” being an integer in a range from 1 to n.

摘要： A management device detects whether any normal monitoring module that has not been tampered with exists by referring to monitoring results received from an information security device and selects, when existence is detected, one of the monitoring modules and assumes that the selected monitoring module has been tampered with. The monitoring device then successively applies a procedure to monitoring modules other than the selected monitoring module by referring to the monitoring results, starting from the selected monitoring module, the procedure being to assume that any monitoring module determining that a monitoring module assumed to have been tampered with is normal has also been tampered with. As a result of the procedure, when all of the monitoring modules are assumed to have been tampered with the management device determines the selected monitoring module to be a normal monitoring module that has not been tampered with.

摘要： A malicious-module identification device identifies and deactivates a malicious module operating in an information processing device connected thereto via a network. The malicious-module identification device is provided with a reception unit for receiving results of tampering detection from a plurality of modules for detecting tampering, and a determination unit for assuming that a module among the plurality of modules is a normal module, determining, based on the assumption, whether a contradiction occurs in the received results of tampering detection and identifying the module assumed to be a normal module as a malicious module when determining that a contradiction occurs. A deactivation unit outputs an instruction to deactivate the module identified as the malicious module.

摘要： An update server acquires, from an apparatus, a result of verifications relating to tampering of a protection control module and each of install modules included in an install module group. The update server determines a processing procedure of the apparatus depending on the acquired result of the verifications. Specifically, if it is judged that the protection control module and each of the install modules is unauthentic, then the update server transmits, to the apparatus, an instruction to perform updating of the unauthentic protection control module in preference to a revocation of the unauthentic install module.

摘要： The present invention aims to perform tamper detection on a protection control module without having detection modules come to know the key data and functions thereof. The detection modules of the present invention perform tamper detection by verifying whether or not the correspondence between the input and output data of the application decryption process performed by the protection control module is correct. Furthermore, the present invention offers improved security against leaks of the application output data by the detection modules by having a plurality of detection modules verify different data blocks.

摘要： An information security apparatus includes a plurality of monitoring modules that monitor for tampering. A management apparatus includes a reception unit that receives a plurality of monitoring results each generated by a source monitoring module monitoring a target monitoring module; a detection unit that detects an abnormality by referring to fewer than all of the received monitoring results; and an identification unit that identifies, when an abnormality is detected, a monitoring module that has been tampered with from among (i) a monitoring module that generates a monitoring result related to the abnormality, and (ii) one or more monitoring modules identified by tracing back through a chain of monitoring modules consecutively from the target of monitoring to the source of monitoring, starting from the monitoring module that generates the monitoring result related to the abnormality.
