The invention relates to a method for matching a number N of reception equipment ( 2 ) with a number M of external security modules ( 6, 8 ), each reception equipment ( 2 ) being provided with a unique identifier, and each external security module ( 6, 8 ) having a unique identifier and containing information about access rights of a user to digital data distributed by an operator. This method comprises a configuration phase comprising the following steps: memorise a list of identifiers of reception equipment ( 2 ) in each external security module ( 6, 8 ), memorise a list of identifiers of external security modules ( 6, 8 ) in each reception equipment ( 2 ), and a check phase consisting of authorising access to data if the identifier of an external security module ( 6, 8 ) connected to a reception equipment ( 2 ) is present in the list memorised in this reception equipment ( 2 ), and if the identifier of said reception equipment ( 2 ) is present in the list memorised in said external security module ( 6, 8 ), otherwise disturb access to said data.
