摘要:
A computer resource verifying method verifies computer resources introduced into a client device. The computer resource verifying method includes performing, by the client device, client side processing including verification of individual computer resources introduced into the client device and information collection for a dependence relation between computer resources; performing, by a server device, a server side processing by receiving information on a result of the client side processing performed in the performing of the client side processing to perform verification of the dependence relation between computer resources; and determining, by the server device, whether the client device is normal based on a verification result of the computer resources and a verification result of the dependence relation between computer resources.
摘要:
Security of an information processing apparatus is ensured by performing biological information authentication and collecting the environment information about the information processing apparatus. The information processing apparatus transmits the collected environment information to a first authentication apparatus. An electronic certificate issued by a second authentication apparatus and information encrypted with a secret key issued by the second authentication apparatus are transmitted to the first authentication apparatus. The first authentication apparatus acquires the public key of the second authentication apparatus and the public key of the information processing apparatus so as to decrypt the encrypted information, and judges whether or not the decrypted information is proper. The first authentication apparatus refers to an environment information database and the transmitted information, and judges whether or not the transmitted environment information is proper. When all the authentications by the biological information authentication, environment information authentication and electronic certificate authentication are successful, the information processing apparatus is judged to be safe.
摘要:
A method for verifying electronic software code integrity may comprise providing a list of encryption keys to a client, encrypting a software code packet using one of the plurality of encryption keys, delivering the encrypted software code packet to the client, and informing the client to choose an encryption key for decryption based on the specific time factor. Each encryption key on the list may correlate to a respective time factor. The one of the plurality of encryption keys may be chosen from the list based at least in part on a specific time factor.
摘要:
An electronic data storage system stores electronic data with attaching an electronic signature, and output the electronic data along with the attached electronic signature, which decreases the operation costs with a simple operation. By using a public key-based signature, a third party can verify the data, and by using a secret check code, the electronic signature at registration is always valid without risk of falsification. Also by attaching an electronic signature at access, the validity of the stored data is assured, and a third party can verify the data. By using all of these features, the verification by a third party becomes possible over the long term. In this way the long term storage of electronic data is implemented.

The system includes the monitor agent that analyzes log of an entity. When an abnormality is detected, the monitor agent notifies about the abnormality to the control manager. The control manager decides a countermeasure and a countermeasure request party from the database and informs them to the action agent which the countermeasure request party. The action agent implements the countermeasure.
摘要:
The apparatus controls access to the contents. The apparatus comprises MO device, MPEG2 decoder, and MO media as physical elements. Information for identifying these physical elements (identifying information) is allocated to each of these physical elements. License information, indicating whether access to the contents is to be allowed or not, is recorded on a MO media. Access to the contents recorded on the MO media is controlled based on the license information and the identifying information.
摘要:
A file processing unit comprises a first signature information producing unit that produces first signature information in accordance with a predetermined rule utilizing the data of a file designated by a file close request issued in an application used in a computer system, and a signature information storage control unit that stores the first signature information, correlated with the file designated by the file close request, in a storage unit.
摘要:
A cryptographic communication method is provided in which a cryptographic communication is performed by an easy operation even if both enciphered data and unenciphered data are mixed to be handled. In the transmission side, a communication key is used for enciphering data to be transmitted, and in the reception side the same communication key as in the transmission side is used for decoding received data. In the transmission side, an individual key that is different from the communication key is used for enciphering the data to be transmitted, the enciphered data are decoded by using the individual key first, and then the decoded data are enciphered by using the communication key so that the enciphered file can be transmitted.
摘要:
An apparatus for granting electronic signature to a data includes an identification-data acquiring unit that acquires identification data for identifying an owner of a secret key that is used to create the electronic signature, an authorization-data acquiring unit that acquires authorization data corresponding to the identification data acquired, and a signature-granting determining unit that determines whether to grant the electronic signature to the data based on the authorization data acquired.
摘要:
The recording/reproducing apparatus of the invention can discriminate an illegally copied information recording medium by reading an irreversible area from the information recording medium on the basis of judgement on presence of irreversible data. The information recording medium of the invention includes a buffer area which is not affected by heat used in recording the irreversible data, and the judgement is obtained with the buffer area excluded. Therefore, a mistake in judging whether or not the irreversible data is recorded in the loaded information recording medium can be avoided.
