Abstract
There is provided a communication system capable of reducing the burden of the terminal that is connected to the Internet via the communication network such as the mobile telephone network, whose security is ensured, and is used to carry out the electronic commerce and the banking service. An encryption communication request generating portion ( ) of a client system ( ) sends out a security request of a communication route to a gateway server unit ( ), an encryption communication controlling portion ( ) of the gateway server unit sets up encryption communication between a content server unit ( ) and the gateway server unit in response to this, the content server unit encrypts data to be transmitted to the client system and then transmits it to the gateway server unit, and an encryption communication controlling portion of the gateway server unit decrypts this data and transmits it to the client system. Encryption/decryption processing systems are not needed in the client system and thus the burden can be reduced.
