NXP, the RFID manufacturer, has announced the launching of new generation of mifare RFID chips: mifare plus. This new version has enhanced the security comared to previous mifare classic. For instance, it implements 128-bit AES, and more diversity for the identification. Mifare Plus seem to have an easy migration path from mifare clasic.
For memory, it was the NXP mifare classic that was recently hacked. This is a nice timely answer to this hack. How long will the new generation resist?
