Abstract
This invention relates to a security module comprising a microprocessor, a program memory containing at least one operating program and unique identification means of said module. This security module is characterized in that the identification means are constituted by a set of unique and artificial computer codes, compatible with their execution by said microprocessor of the module and stored in the program memory.
The invention also concerns a personalization method of a security module by a unique identifier, this module comprising a microprocessor and a program memory containing at least one operating program. The method of the invention is characterized in that it includes the steps of generation of a unique set of computer codes, called artificial computer codes and the writing of this set of codes in the program memory in specific memory locations.
