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