1. A security method for the detection and/or control of unauthorized vehicles (10a, 10b, . . . ) among a large number of authorized vehicles (12a, 12b, . . . ) within a controlled geographical zone (2), characterized in that all authorized vehicles are equipped with active licenses (60a, 60b, . . . ) planned to perform a cryptographic action involving a secret cryptographic key (64), and the controlled geographical zone is equipped with automatic control points (20a, 20b, . . . ), and optionally with manual control points (40a, 40b, . . . ), each automatic control point detecting all vehicles crossing a specific road section (21) in its vicinity, and each manual control point selecting vehicles by the action of an operator, the vehicles detected by the automatic control points and the vehicles selected by the manual control points being hereafter referred to as designated vehicles, both types of control points being planned to acquire the results of said cryptographic actions performed by the active licenses of said designated vehicles, a cryptographic authentication algorithm involving a validation key (74) being further performed upon each acquired said result, both types of control points being further planned to associate said acquired results to said designated vehicles, the designation of the vehicles, the acquiring of said results, and the performing of the cryptographic authentication algorithm upon said acquired results not requiring a change in the motion conditions of the vehicles, in particular their velocity, classifying as unauthorized at least vehicles which have been designated but whose said results either have not been acquired or have not been cryptographically authenticated, an alert message being transmitted to enforcement authorities for each vehicle which has been classified as unauthorized, allowing in such a way for an immediate intervention and a possible interception of the unauthorized vehicles, at least some of the control points, hereafter referred to as particular control points, being moreover planned to acquire physical characteristics of said designated vehicles, allowing their direct recognition, said alert message including in this case said physical characteristics.
