A system for securing the access to a destination of a virtual private network (VPNA) connected to a nominal access router (PE) includes at least one core router (P) adapted to: detect a failure affecting communication with the nominal access router (PE); and switch the traffic to a protector access router (PE) in a back-up tunnel bypassing the nominal access router (PE). The protector access router (PE) is adapted: to replace, in an MPLS packet, a nominal VPN label specific to the nominal access router (PE) by a back-up VPN label specific to a back-up access router (PE) connected to that destination; and to redirect said packet to the back-up access router (PE) in a tunnel bypassing the nominal access router (PE).

System for securing the access to a destination in a virtual private network

The method consists in: a user terminal issuing an access request to an access or IP service provider, the request containing user identification and authentication data with the provider and with an access and IP transport network operator, the access request being transmitted via the access network to an authentication server of the access or IP service provider; previously transmitting the access request to an authentication server of the network operator; the authentication server performing a procedure to authenticate the user on the basis of user identification data with the provider; and transmitting a response message to the user terminal, which response message contains the results of the user authentication by the authentication servers.
