摘要： Cryptographic communication between communication terminals can be realized even when a plurality of cryptographic algorithms are present, and secure cryptographic communication for a longer time is realized without increasing a processing overhead at each of the communication terminals. A key management server manages cryptographic algorithms that can be used by each of the communication terminal, and searches for a cryptographic algorithm common to the communication terminals, and notifies each of the communication terminals of the cryptographic algorithm found by the search together with plural key generation informations, each piece containing a key to be used in the cryptographic algorithm or a key type for generating the key. Each of the communication terminals sequentially switches the plural key generation informations notified from the key management server, and performs the cryptographic communication with a communication counterpart in accordance with the cryptographic algorithm notified from the key management server.

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： 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： In an encryption communication using VPN technologies, a load on a VPN system becomes large if the number of communication terminals increases. When an external terminal accesses via an internal terminal an application server, processes become complicated because it is necessary to perform authentication at VPN and authentication at the application server. A management server is provided for managing external terminals, internal terminals and application servers. The management server authenticates each communication terminal and operates to establish an encryption communication path between communication terminals. Authentication of each terminal by the management server relies upon a validation server. When the external terminal performs encryption communication with the application server via the internal terminal, two encryption communication paths are established and used between the external terminal and internal terminal and between the internal terminal and application server.

摘要： In order to reduce network loads in a large system, provided is a representative aspect of this invention is as follows. That is, there is provided a SIP server coupled to at least one client via a communication line to control a communication session of the at least one client. The SIP server receives a SIP message transmitted from the at least one client, transfers the received SIP message to one of another SIP server and another one of the at least one client, and analyzes the received SIP message. The SIP server comprising a storage unit for storing a result of the analysis. The SIP server compares the result of the analysis and a SIP message received after the analysis, rewrites the SIP message based on a result of the comparison, and changes a transfer destination of the SIP message based on the result of the comparison.

摘要： A validation authority for certificates searches for and verifies paths and certificate revocation lists periodically, and classifies the paths into valid paths and invalid paths in accordance with the results of the validations, so as to register the paths in databases beforehand. Besides, in a case where a request for authenticating the validity of a certificate has been received from an end entity, the validation authority judges the validity of the public key certificate by checking in which of the valid-path database and the invalid-path database a path corresponding to the request is registered. On the other hand, in a case where the path corresponding to the validity authentication request is not registered in either of the databases, the validity of the public key certificate is authenticated by performing path search and validation anew.
摘要翻译：证书的验证机构定期搜索和验证路径和证书撤销列表，并根据验证结果将路径分类为有效路径和无效路径，以便事先在数据库中注册路径。此外，在从终端实体接收到认证证书的有效性的请求的情况下，验证机构通过检查有效路径数据库和无效路径数据库中的哪一个来判断公钥证书的有效性登记与请求对应的路径。另一方面，在与有效认证请求对应的路径未登记在任一数据库中的情况下，通过重新进行路径搜索和验证来认证公钥证书的有效性。
