VPN SYSTEM AND OPERATION CONTROL METHOD THEREOF

Title:

VPN SYSTEM AND OPERATION CONTROL METHOD THEREOF

Document Type and Number:

Japanese Patent JP2011077769

Kind Code:

A

Abstract:

To improve the security of VPN communication.

A VPN management server 11 transmits a seed to each of a client computer 1 and a VPN server 13. The client computer 1 generates a VPN password based on the seed using a specified algorithm, and transmits the generated VPN password to the VPN server 13. The VPN server 13 also generates a password based on the seed using the same algorithm as that of the client computer 1. If the VPN password transmitted from the client computer 1 matches with the VPN password generated by the VPN server 13, authentication is successful and the VPN is permitted to be used. Even if seed leak occurs, no VPN passwords is generated without algorithm analysis, so that the security is improved.
