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. | 02-26-2009 |

20090113203 | Network System - An encryption communication module on the side of a service providing server reports a global IP address allocated to an NAPT router on the service providing server side and a port number of an outside UDP header used on the global side to an authentication/key exchange server. When receiving an encryption packet from an encryption communication module on the user terminal side, the encryption communication module on the service providing server side overwrite a source/destination IP address of an inside IP header by a source/destination IP address of an outside IP header. The encryption communication module further changes a source port number of an inside TCP•UDP header to a unique value for each communication session in the encryption communication having the same source IP address in the outside IP header. The inverse header change is made when the packet is transmitted to the encryption communication module of the user terminal side. | 04-30-2009 |

20100017527 | SIP SERVER AND COMMUNICATION SYSTEM - 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. | 01-21-2010 |
