ISO/IEC 14443 reader IC
11.6.4.1
Authent2 command effects
If the Authent2 command is successful, the authenticity of card and the MFRC531 are
proved. This automatically sets the Crypto1On control bit. When bit Crypto1On = logic 1,
all further card communication is encrypted using the Crypto1 security algorithm. If the
Authent2 command fails, bit Crypto1On is cleared (Crypto1On = logic 0).
Remark:
The Crypto1On flag can only be set by a successfully executed Authent2
command and not by the microprocessor. The microprocessor can clear bit Crypto1On to
continue with unencrypted (plain) card communication.
Remark:
The Authent2 command must be executed immediately after a successful
Authent1 command; see
Section 11.6.3 “Authent1 command 0Ch”
. In addition, the keys
stored in the key buffer and those on the card must match.
