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.

Each terminal registers the key generation information into each session management server, the information including a plurality of setting items necessary for determining set values to generated a key to be used by itself, and set value candidates which are stored in the setting items.When the encryption communications are established between the terminals, the individual session management servers and a key generation information management server are associated, so that the key generation information management server selects the algorithm suite based on the key generation information. The session management server generates the parameters based on the selected algorithm suite, acquires the information on the selected algorithm suite from the key generation information management server, generates the key for the encryption communications based on that information and distributes the key to the each terminal.

摘要:
An encrypted communication system is provided, in which an encryption key for use in encrypted communication and settings information for the encrypted communication are distributed to each of a plurality of communication devices performing encrypted communication within a group, and in which traffic generated by distributing the encryption key and the like can be reduced. In the encrypted communication system according to the present invention, information including a key for use in the intra-group encrypted communication or a seed which generates the key is distributed to the communication devices belonging to the group that are participating (e.g., logged in) in the intra-group encrypted communication.
摘要:
A data communication method for forwarding a session control message designating a destination server with an IP address to the destination server via a session management server, wherein, when an application program or encrypted communication software on a client issues a connection request designating a destination server with an IP address, the client or the session management server automatically converts the IP address into a desired resource identifier identifiable a domain, thereby to determine the domain to which the received connection request message should be forwarded.
摘要:
In a data communication method and a data communication system, a session control message designating a destination server with identification information unique to application is transferred to the destination via a session management server. When an application program or encrypted communication software on a client issues a connection request designating a destination with identification information unique to application, the client or the session management server automatically converts the identification information into a desired resource identifier identifiable a domain to thereby determine a domain as the destination of the received connection request message.

A communications audit support system is provided, which makes it possible to audit communications of an arbitrary encrypted communication session at any time. The communications audit support system of the present invention stores key information used for encrypted communication in a key management DB in association with a key ID each time the key information is created, stores IP addresses of a user terminal and a service providing server which perform an encrypted communication session using the key information in a communication state management DB in association with the key ID, and stores an encrypted packet sent in an encrypted communication session in a packet DB in association with IP addresses of a sender and a receiver of the encrypted packet.
