Smart card reader with microcontroller and security component
TLDR
In this article, a smart card reader dedicated to a particular application and using both a microcontroller (MC) whereof the read-only memory determines the operation of the application, and a security component (CS) executing, under the microcontroller control, sub-programmes related to application security (authentication, confidential programs and the like).Abstract:
The invention concerns smart card readers dedicated to a particular application and using both a microcontroller (MC) whereof the read-only memory determines the operation of the application, and a security component (CS) executing, under the microcontroller control, sub-programmes related to the application security (authentication, confidential programmes and the like) In order that the application manager may access certain zones of the security component memory, it is provided that the microcontroller can automatically shift into a so-called 'transparent' mode, when a specific access code transmitted by the test card is recognised In this mode, the reading or writing instructions of a memory zone of the security component, transmitted by the test card, are interpreted by the microcontroller as being reading or writing instructions of a memory zone of the security component and not of the microcontroller The invention is applicable to portable readersread more
