1  Overview 

 
VPN is the acronym for « virtual private network » ; it is a mechanism 
which allows to connect safely 2 end-points, two routers for instance or 
one router and one PC, through a network not intrinsically safe. 
 
Once a  VPN has been set between two routers , any device of the first 
network can communicate with any device of the second one as if the two 
routers were directly connected with an Ethernet cable.

2  Functions 

 
A VPN provides the functions described hereafter : 
 

Authentication 

 The VPN ensures that the party with which the communication is set is 
actually

 the one it claims to be. 

 

Data integrity 

The VPN mechanism ensures that information being transmitted over the 
public Internet is not altered in any way during transit
