Problems solved by technology

[0004] However, in the existing IPSec-VPN system, it is necessary to install a dedicated application program on the client side, and the burden on the administrator is large.
Moreover, this is like opening a hole in a secure private network, which poses a security risk
[0005] On the other hand, in the case of SSL-VPN, access is possible only through authentication with ID and password, so there is a problem that the security strength is low, and the usable applications are limited to the WEB

Abstract

The invention discloses a virtual network building system, a virtual network building method, a small terminal, and an authentication server. The virtual network building system of the invention includes a small terminal and an authentication server. The small terminal includes an identifier transmission unit automatically transmitting an identifier to the authentication server via a client terminal in a state in which a connection unit is connected to the client terminal. The authentication server includes an authentication unit performing authentication on the basis of the identifier of the small terminal, a distribution unit distributing software for encrypting communication to the client terminal according to selected communication protocol and encryption method, a reception unit receiving access request information regarding a request for access to the target apparatus, which is automatically transmitted from the distributed software, and a redirect unit making a proxy response of access of the client terminal to the target apparatus in response to the received access request information.

Description

technical field [0001] The invention relates to a virtual network construction system, method, small terminal and authentication server. Background technique [0002] In recent years, systems that construct virtual networks such as VPNs (Virtual Private Networks) have been used instead of dedicated lines as systems for accessing secure private networks such as organizations from the outside. VPN encapsulates and communicates communication data, so that ordinary users of public lines cannot see it, and it is realized by adopting tunnel technology. [0003] In the past, for example, IPSec-VPN (Security Architecture for Internet Protocol-VPN) or SSL-VPN (Secure Socket Layer-VPN) was used as the VPN system. IPSec-VPN encrypts IP data packets through the IPSec protocol to perform access control on the network layer. On the other hand, SSL-VPN uses SSL to encrypt IP data packets for access control on the application layer. [0004] However, in the existing IPSec-VPN system, a d...
