Method of producing electronic security module e.g. for payment card, involves using test value stored in smart card for testing data authentication

摘要

A production procedure for electronic security elements, in particular smart cards, involves at least one test value, especially a public code/key of the purchaser of the smart card, for storage in a storage zone of the chip, and during initialization of the electronic security module, an addressable test value is used. The test value stored in the smart card is used to test the authentication of the data introduced during initialization, and with a negative outcome of the verification, initialization is discontinued. An Independent claim is given for a security module containing a chip with ROM mask and EEPROM.
