it is possible to decrypt a sniffed Auth key offline


I would like to ask if it is possible to decrypt a Desfire Auth session / key "offline" if I have previous sniffed the communication between Card an reader?
Means, can I calculate / brute force the plain PICC or AID Key with a computer or FPGA if I have sniffed a successfully authentication?

thanks a lot.
