Publication number: 20070250547Abstract: An agent program 141 stores a log file in a storage device 150. By controlling an access to the storage device 150 according to volume management information 153, the storage device 150 prevents the log file from being updated. A manager program 142 communicates with the agent program 141 to collect the log file. On the completion of the log collection, the manager program 142 adds a signature to a log deletion message by use of a security chip 105. Then, the agent program 141 verifies the signature by use of a security chip 104 to judge that a log deletion request is valid. After that, the volume management information 153 which has been used to protect the log file is rewritten so that the protection is removed.Type: ApplicationFiled: March 27, 2007Publication date: October 25, 2007Inventors: Satoshi Kai, Masato Arai, Akira Morita, Naoto Sato

Patent number: 7137025Abstract: A key managing system including information transmitting apparatus which transmits a date and time when secrecy protection is ended to a key controlling apparatus. The key controlling apparatus searches a key control table for an encryption key associated with a decryption key and the date and time. The key controlling apparatus transmits an encryption key from the search to the information transmitting apparatus. The key controlling apparatus discloses a decryption key for the present date and time to an information receiving apparatus in response to a request for a decryption key. The information transmitting apparatus, upon receipt of the encryption key, encrypts information using the encryption key and transmits the encrypted information to the information receiving apparatus. The information receiving apparatus, for the present date and time matching with the date and time, acquires a disclosed decryption key and decrypts the encrypted information by using the decryption key.Type: GrantFiled: February 28, 2002Date of Patent: November 14, 2006Assignee: Hitachi, Ltd.Inventors: Hiromichi Ito, Masato Arai
