I have a script for stm32 which can read cards and send everything via sms using the rc522. I need a script that will use authentication when reading the EV1 desfire card. You will need to calculate CMAC like here: [login to view URL]
The purpose of this is to have a reader that can read cards that can't be copied.
Okay!
My name is Jaspreet & I'm part of larger embedded hardware and firmware development team. I already programmed STM32 MCU like STM32F4Discovery and STM32F030-Discovery using STM32CubeMX and IAR EWARM
Kindly spare 10 minutes for the interview.
We will be glad to hear from you!
