摘要

The method involves producing a portable electronic object (OEP) constituted of a electronic certificate of authenticity storing unit, security processor and internal memory of GSM mobile telephone. The electronic object is transmitted to an authorized user (CL) through a transmission path (21). A personal identification code (PIN) serving as an activating key in an asymmetric encrypting process is generated and transmitted to the user via a transmission path (27). An identity of the user is verified during delivery of the personal code. An independent claim is also included for a personal device for execution of authenticated transaction.
