Protocol
Using CryptoAPI, generates KEY_EXCHANGE containers while the card is not full, then select the first container and perform signature 20 times. Same for decryption.
Times are computed end-to-end at the CryptoAPI level (includes signature verification – this 100% time is not related to the card).
Note:
Some contactless cards couldn’t generate RSA key until the card is full. The cards get hot and lost the RFID connection.
