Embodiment Construction

[0041] Embodiments of a communication system using the present invention will be described below with reference to the drawings.

[0042] figure 1 is a block diagram showing the configuration of an example of a communication system using the present invention. The communication system 1 of this example has a communication terminal 2 such as a personal computer, a mobile phone, etc. equipped with a network connection section 21, and a portable electronic device 3 (hereinafter referred to as "token") capable of communicating with the communication terminal 2 . It can be connected to a designated network 5 via a communication network 4 such as the Internet.

[0043] The communication terminal 2 has a virtual network switch 22 that can forcibly change the destination of data to and from the network 5 connected thereto via the network connection section 21 . Using the virtual network switch 22, the data sent from the network 5 to the communication terminal 2 is transmitted to th...

Abstract

The communication terminal of a communication system comprises a virtual network switch which can alter the destination of data being transmitted and received between the communication terminal and a network forcibly, wherein data is transmitted and received between the network and the communication terminal through a portable electronic device. Various functions, including a security function, can be supplemented by providing the function of software mounted on the portable electronic device itself to the communication terminal. Even if a communication terminal connected directly with the network is not provided with such functions as VPN, firewall or virus check, high-safety communication can be ensured utilizing these security ensuring means mounted on the portable electronic device.

Description

technical field [0001] The invention relates to a communication system composed of a communication terminal with network communication function and a portable electronic device capable of communicating with the communication terminal. Specifically, it relates to a communication system capable of accessing various types of networks using a communication terminal in accordance with a communication security level preset in a portable electronic device. Background technique [0002] Usually, software and its setting information, etc. required when connecting a communication device to a public network such as the Internet are loaded in advance into the communication device, or are temporarily installed in the communication device, and the Software runs in the communication device. When it is necessary to ensure security during communication, software for ensuring security is also loaded in advance or temporarily installed in the communication device. [0003] Such means used to...
