generate or use only the diversified keys. MIFARE SAM AV3 supports two types of key diversification: • old method, based on classical encryption, and • new method, based on CMAC calculation In this document, only the key diversification based on CMAC calculation is discussed, as it is the recommended algorithm. AES (128 and 192-bit key length) and TDEA (2-key an First, I prepare a MIFARE DESFire EV1 with an application AID = 010203 (here I say use two keys for the application) and put a file to the application with file write permission 01, which means use key #1 for authenticate. In our example we use a diversified key regarding AN10922, AES128 CMAC method (see link above) 1. Key diversification: With key diversification each card has a key or keyset which is different from each other card. 2. Fraud detection: The ability to find out that a fraudulent card exists. 3. Mechanism to stop deployment of fraudulent cards: This can be either or both of: a. Black listing/ whitelisting [AN10922] specifies the key diversification algorithms used by the MIFARE SAM AV3. Support for these algorithms was added to `libfreefare` via pull-request nfc-tools#79. However, while every attempt was made to write a faithful implementation, the implemented code did not properly handle cases where the diversification data was less than or equal to the block size of the cipher: 16 bytes for AES, and 8 bytes for DES. This bug was identified in issu DESFire key diversification does not agree with AN10922 mifare_key_deriver does not compute the right diversified key when the input is less than the key block size. This problem will be very common for something like UID-based diversification, since the UID will always be less than the key block size
AES-128 bit key diversification in itself is not likely to be vulnerable. MiFare chips do protect against cloning as the card specific keys must be present. Of course, since MiFare itself is vulnerable, the anti-cloning part is likely to be affected. - Maarten Bodewes Sep 10 '12 at 19:5 Reported by email@example.com, Jun 7, 2012 Mifare Classic uses two types of diversification, old and new. The new type is very very similar to DESFire diversification, actually it is 100% the same, but the for DESFire the final key is taken from the last 16 bytes, for the classic it is first 6 bytes of the last 16 bytes. Will there be a fn that simply returns Classic type keys? ---- Comment 1 by project member firstname.lastname@example.org, Jun 7, 2012 Thanks for reporting issue. Could you provide. Key Diversification. Mit neuen Script-Funktionen bietet ChipMan ab der Version 22.214.171.124 die Möglichkeit einer Key Diversification. Zusätzliche Script-Funktionen: AES,<source hex >,<key hex >,<target hex > 128 Bit AES Verschlüsselung; 3DES,<source hex >,<key hex >,<target hex > TripleDES Verschlüsselung; CRC32,<source hex>,<init hex>,<target hex> CRC Berechnun This is known as key diversification (diversification is derivation using a master key and device ID). This insures that even extracting a key from a card can't compromise the key of other cards. The reader-side cryptography is typically performed by a SAM, perhaps similar to this one. Thus UID/RID might be the device ID used for diversification. Or not. It is not secret, most often can be read (at least in EV1) and thus cloned; but the associated diversified key can not be read, and that's. Key diversification is a powerful security capability MIFARE added to its DESFire technology. Like previous MIFARE keyed security features, key diversification requires system integrators and vendors who deploy it to address management of their security keys. That is why Idesco's security key management service will begin offering customers a range of options for also managing diversified security keys. They will be able to program and manage their keys themselves with a coding.

SAM AV2 can be an optimum secure solution for this key diversification process. The master (base) key can be stored securely in the MIFARE SAM AV2 and can be used to generate or use only the diversified keys.

Python implementation of Mifare AES-128 simmetric key diversification, as described in document AN10922 - key_generation.p The MIFARE SAM AV3 raises the bar on flexibility by supporting programmable logic, too, so you can integrate a proprietary algorithm for key diversification or implement a full business flow that executes with just one call. Developers can also write their own code while re-using the intrinsic cryptography functions of the MIFARE SAM AV3. To simplify the development of customized logic - a process that requires eligibility, tool investment, and specialized skills - NXP partners with.
