摘要： It takes time for an encryption data communication system to transfer encrypted data, because negotiations of security parameters are necessary prior to communications in order to protect security and integrity of a SIP message or public key cryptography is required to be used for an encryption process, a decryption process., an digital signature process and an digital digital signature verification process each time a SIP message is transmitted/received. When a SIP message is transferred between two entities, the message is encrypted by shared information if the information is being shared between the entities, or the message is encrypted by the public key of the transmission destination entity if the shared information is not being shared. The encrypted message contains shared information to be used for the transmission destination entity of the encrypted data to encrypt or decrypt the message, during communications after the encrypted data is generated.

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： 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： An encrypted communication method, and a system for the method, can transfer a session control message designated by identification information inherent to an application to a connection destination through a session management server. When an application program of a client or encrypted communication software issues a connection request in the form designating an application server by identification information inherent to each application, the identification information is automatically changed to a desired address-of-record capable of domain identification and a transfer destination domain of a reception message is judged.

摘要： When a cryptographic communicating part 208 of the communication support server 20 exchanges information with the information processing units 14, if the term of validity of a first key stored in a cryptographic key storing part 200 and corresponding to the identification information of the information processing unit 14 does not expire, the cryptographic communicating part 208 performs the cryptographic communication with the information processing unit 14 using the first key, without performing a process of authenticating the information processing units 14. When the term of validity of the first key expires or the first key corresponding to the identification information of the information processing units 14 is not stored, the key sharing part 202 shares the first key with the information processing units 14, and the cryptographic communicating part 208 performs the cryptographic communication with the information processing units 14 using a newly shared first key.
