Method and system for authenticating at least one terminal requesting access to at least one resource

Abstract

For authenticating at least one terminal requesting access to at least one resource, an authentication server performs: obtaining for each terminal at least one piece of authentication information; transmitting to a gateway device at least one checking function, or coefficients thereof. Each piece of authentication information is representative of a value such that, when inputted to respective checking function(s), the checking function(s) return(s) a predefined value. The gateway device performs: receiving from one terminal a request for getting access to the resource(s), said request being received in conjunction with a piece of authentication information; retrieving a checking function applicable to the received request; inputting the piece of authentication information provided by the terminal into the retrieved checking function, for obtaining an authentication result; accepting the request for getting access to the resource(s), when the authentication result equals said predefined value; and rejecting the request otherwise.
