Mainstream contactless smart card IC

8.6 Security level 3

The operation in security level 3 is solely based on the ISO/IEC 14443-4 protocol layer.

The usage of the backwards compatibility protocol is not possible.

In security level 3, a mandatory AES authentication between PICC and reader is

conducted, where two keys are generated as a function of the random numbers from the

PICC and the reader as well as of the shared key. These two session keys are used to

secure the data which is exchanged on the interface between the card and reader. One of

the two keys is used to ensure the confidentiality of the command and the response while

the other key ensures the integrity of the command and the response.

All commands carry a MAC, such that the PICC will only accept commands from the

reader with which it is authenticated. Tampering of operands and messages is detected by

checking the MAC. Also all responses contain a MAC, so that the reader on each

response knows that neither the command nor the response has been tampered with.

Each response carries a MAC. When the appropriate MAC is received, due to linking of

MACs, the reader knows that the command and commands before it was properly

executed.

All commands between two consecutive first authenticate commands belong to one

transaction and the MACing mechanism assures integrity of the whole transaction.
