Product short data sheet PUBLIC Rev. 3.2 — 21 February 2011 163532 9 of 20 NXP Semiconductors MF1PLUSx0y1 Mainstream contactless smart card IC • Security Level 2 8.2.2 ISO/IEC 14443-4 Protocol The ISO/IEC 14443-4 Protocol (also known as T=CL) is used in many processor cards. This protocol is used for the MIFARE Plus with the following security levels: • Security Level 0: all commands • Security Level 1: only the security level switch and originality function • Security Level 2: updating AES keys and configuration blocks as well as the security level switch and originality function • Security Level 3: all commands 8.3 Security level switching The MIFARE Plus X offers a unique feature to support migration from CRYPTO1 based systems to AES based operation. The migration on the card-side is done using different security levels supporting different cryptographic algorithms and protocols. There are four security levels: • Security level 0: initial delivery configuration, used for card personalization • Security level 1: backwards functional compatibility mode (with MIFARE Classic 1K and MIFARE Classic 4K) with optional AES authentication • Security level 2: 3-Pass authentication based on AES followed by MIFARE CRYPTO1 authentication, communication secured by MIFARE CRYPTO1 The MIFARE CRYPTO1 uses session keys derived from the AES and MIFARE CRYPTO1 authentication. • Security level 3: 3-Pass authentication based on AES, data manipulation commands secured by AES encryption and an AES based MACing method If the card is a L3 card the Commit Perso command will switch the card directly from security level 0 to security level 3 instead of security level 1. The security level switching (i.e. from security level 1 to security level 3) is performed using the dedicated AES authentication switching keys. The security level can only be switched from a lower to a higher level, never in the opposite direction. 8.4 Security level 0 Security level 0 is the initial delivery configuration of the PICC. The card can be operated either using the backwards compatibility protocol or the ISO/IEC 14443-4 protocol. In this level, the card can be personalized including the programming of user data as well as CRYPTO1 and/or AES keys. In addition, the originality function can be used. The following mandatory AES keys must be written, using the Write Perso command before the PICC can be switched to security level 1 or security level 3 (for L3 card). |
