Virtual private network (VPN) connection logic (VPN technology) and security token boosting with the pin code

VPN system used to access the intended use is safe, but many of the tokens have been shown to be not safe.Pin code so as to increase the security for new configurations are needed.Through this and similar methods of attack and malicious recently in order to prevent information leakage has become an important issue that needs to be developed.VPN as a secure access system seen in the old method or the fixed password generated by the token (after 60 seconds a new feature code generation) pin input algorithm source code stolen from suppliers because of the possibility of additionally creating only the user will know before the four digit pin creation also is sufficient to improve safety.
