    Hi;

    I created an application with ‘CA 33 33 33 0F 0A’ …Then I sent 90-0A-00-01-00-00 (begin authentication procedure)…

    it responsed me 1D-A4-56-2E-78-43-F6-CB (encrypted rndB)

    Now I should Decrypt and build Rondom B..

    I am sending to picc 1D-A4-56-2E-78-43-F6-CB (encrypted rndB), it returned 67 00 so it is wrong way.

    How can I decrypt rndB and generated rndA?

    akdrmrk,

    Have you signed an NDA with NXP? You will need to do this to get access the required documents.
