RFID standard iclass with proxmark3

Hi all, I need someone to help to make a programme for rfid iclass standard security card key. If you are able to use proxmark3 or own programme to figure the standard master key for iclass/(se), please contact me for further info. Ex. how to get standard card key The first attack exploits a total of four weaknesses in the cipher, key diversification algorithm and implementation. In order to execute this attack the adversary first needs to eavesdrop one legitimate authentication session between card and reader. Then it runs 219 key updates and 222 authentication attempts with the card. This takes less than six hours to accomplish when using a Proxmark III as a reader and recovers 24 bits of the card key. Finally, off-line, the attacker needs to search for the remaining 40 bits of the key. Having recovered the card key, the adversary gains full control over the card and first attack requires one eavesdropped authentication trace with a genuine reader (which takes about 10ms). Next, the adversary needs 222 authentication attempts with a card, which in practice takes approximately six hours. To conclude the attack, the adversary needs only 240 off-line MAC computations to recover the card key. The whole attack can be executed within a day
