All details about mifare crypto1 algorithm and protocol disclosed

Henryk Ploetz has released his thesis on mifare protocol and cryptographic weaknesses, which is to the best of my knowledge the most complete publicly available documentation about the mifare CRYPTO1 system.

Congratulation to him and his peers (starbug, Karsten Nohl and others) on this great work. I still hope I could have played a more active role in the security research on mifare. But it's good to see that as imperfect as they are, OpenPCD and OpenPICC fulfill their duty as toolkit to enable security research on RFID.
