Application: Method for introducing personalization data in non volatile memories of a plurality of integrated circuits, in particular in integrated circuit cards, corresponding system and computer program product (Patent ID: US20230384969A1)
The patent filed by STMicroelectronics NV describes a method for storing personalization data in a non-volatile memory of an integrated circuit card used to store an operating system. The method involves writing a static data image and a subset of personalization data in the memory, converting commands with a known code to an inner command script, storing the script in a reserved area, decoding and executing the script during activation, and executing the commands. The method ensures secure storage and execution of personalization data specific to the integrated circuit card.
Additionally, the patent includes claims related to the secure element nature of the integrated circuit card, the use of Application Protocol Data Unit (ADPU) commands, reserving memory areas, encryption using Advanced Encryption Standard (AES), and the deletion of applications after execution. The method also allows for the storage of predictable personalization data using substitution techniques and known codes. The patent further extends to computer-readable media storing instructions for executing the method and integrated circuit cards produced using specific packaging techniques. Overall, the patent outlines a comprehensive approach to securely storing and executing personalization data in integrated circuit cards.
