摘要： In response to a sign request including a digital document from a document-creating device 10, a digital-signed-document exchange supporting server 30 canonicalizes the digital document, calculates a digest value thereof, and returns the digest value to the document creating device. When the document-creating device transmits a digital sign created by encrypting the digest value to the digital-signed-digital document exchange-supporting server 30, the server 30 creates a digital-signed document from the digital sign and the digital document, and returns the document to the document-creating device. On the other hand, in response to a validation request including a digital-signed-digital document and a public key from a sign validating device 20, the server 30 compares a value resulting from the decryption of the digital sign with the public key and a digest value of the digital document canonicalized and returns the result to the sign validating device.

摘要： Both a management server and a validation server are installed. Both a terminal and a terminal register setting information which is usable in an encrypted communication in the management server. When carrying out the encrypted communication, the management server searches the registered setting information for coincident setting information. The management server generates keys for the encrypted communications which can be used by the terminals, and delivers these generated keys in combination with the coincident setting information. The management server authenticates both the terminals in conjunction with the validation server. Since the terminals trust such results that the management server has authenticated the terminals respectively, these terminals need not authenticate the respective communication counter terminals.

摘要： When a document creation unit 1 is started, it calculates a hash value of each software piece therein and stores the hash value in a hash value holder 71 and a measurement log document holder 44. The document creation unit 1 accesses a time distribution unit plural times to receive time information therefrom, and records the time information in a log document and a measurement log document. The document creation unit 1 transmits the log document, the measurement log document, and digital signature-embedded hash value information (measurement auxiliary document) in a tamper-resistant device 63 to a document reception device. The document reception device verifies matching of the hash values or digital signature in the document group, confirms software operating environments in the document creation unit 1 from the hash values, and determines whether the time information is correctly managed within the unit 1.

摘要： A system is provided that includes session management servers which mediate a secure communication performed between communication apparatuses. The session management servers create and maintain communication logs for recording at a start and end of the secure communication. The system includes log management servers which manage the communication logs of the secure communication. The communication source apparatus, the communication destination apparatus and the session management servers transmit their own communication logs to the corresponding log management server in the same domain to which they belong. One of the log management servers obtains those communication logs from the others based on a request and performs verification of consistency among them. Accordingly, it is possible to create reliable communication logs of the secure communication performed between the communication source apparatus and the communication destination apparatus.

摘要： A time period which is expended since a request for the authentication of the validity of a public key certificate till the authentication of the validity, is shortened. A certificate validity authentication center VC periodically searches for and verifies paths which extend from a bridge certification authority CAbridge to individual terminal admitting certification authorities CA, and it registers the paths whose verifications have held good, in a path database in association with the respective terminal admitting certification authorities CA. Besides, in a case where the request for the authentication of the validity of a certificate has been made by an end entity EE, whether or not a path associated with the terminal admitting certification authority CA which admits the end entity, and a path associated with the terminal admitting certification authority CA which has issued the certificate being a subject for the request are registered in the path database is checked, and the subject certificate is judged valid only when both the paths are registered.
