A method for fabricating an electronic security module

A method for producing security modules, in particular chip card with the following method steps: 1.1 by the manufacturer of the chip is a Authentikationsmerkmal, in particular a secret key generated; 1.2 the Authentikationsmerkmal is written in the nonvolatile memory of the chip; 1.3, the nonvolatile memory is formed such that the Authentikationsmerkmal can not be read from the memory; 1.4 the operating system of the chip is designed such that using only the Authentikationsmerkmals is possible to access to the memory; 1.5 the smart card manufacturer is provided the Authentikationsmerkmal available for use; 1.6 in the chip, a check of the Authentikationsmerkmals provided with the information stored in the chip Authentikationsmerkmal; 1.7 upon successful verification the Authentikationsmerkmal the chip manufacturer is exchanged for a Authentikationsmerkmal of the pickup of the chip card; 1.8 after replacing the initialization of the chip card takes place.
