[origin: WO9740474A1] An access control system rendered secure by means of a portable storage medium (C) on which is registered an electronic key (CL) comprises electronic key production means (LE) and means ensuring an electronic locking function (L) to authorise access when the storage medium comprises the required electronic key. According to the invention, to transfer the authorisation to make (CL) keys from one production means (LE) to another, a new public key (K') and signature (CER') of this key are loaded into it. The invention is useful in the management of buildings.
