MIFARE is the NXP Semiconductors owned trademark of a series of chips widely used in contactless smart cards and proximity cards. The MIFARE name covers proprietary technologies based upon various levels of the ISOIEC 1. Type A 1. 3. 5. 6 MHz contactless smart card standard. It incorporates AES and DESTriple DES encryption standards, as well as an older proprietary encryption algorithm. According to MIFARE themselves, 1. The technology is owned by NXP Semiconductors, which was spun off from Philips Electronics in 2. Prox Youtube Er' title='Prox Youtube Er' />VariantseditThe technology is embodied in both cards and readers, as well as a contact smart card, in the case of the SAM AV2. All card types are compliant with ISOIEC 1. Type A. The MIFARE name derived from the term MIkron FARE Collection System covers four families of contactless cards MIFARE Classic  Employs a proprietary protocol compliant to parts 1 3 of ISOIEC 1.

MIFARE ClassiceditThe MIFARE Classic card is fundamentally just a memory storage device, where the memory is divided into segments and blocks with simple security mechanisms for access control. They are ASIC based and have limited computational power. Thanks to their reliability and low cost, those cards are widely used for electronic wallet, access control, corporate ID cards, transportation or stadium ticketing. The MIFARE Classic 1. K offers 1,0. 24 bytes of data storage, split into 1. A and B. Each key can be programmed to allow operations such as reading, writing, increasing value blocks, etc. MIFARE Classic 4. K offers 4,0. 96 bytes split into forty sectors, of which 3. K with eight more that are quadruple size sectors. MIFARE Classic mini offers 3. For each of these card types, 1. Also, the very first 1. That brings the net storage capacity of these cards down to 7. MIFARE Classic 1. K, 3,4. 40 bytes for MIFARE Classic 4. K, and 2. 24 bytes for Mini. It uses an NXP proprietary security protocol Crypto 1 for authentication and ciphering. Parts of this article those related to smartphone types need to be updated.

MIFARE PluseditMIFARE Plus is a replacement card for the MIFARE Classic. It provides an easy upgrade of existing infrastructures toward high security. Data management is identical to the MIFARE Classic however, the security management requires the modification of the installed reader base. Other features include 2 Kbytes or 4 Kbytes of memory.

It is less flexible than MIFARE DESFire EV1. MIFARE Plus was publicly announced in March 2. Q1 2. 00. 9. 4MIFARE Plus, when used in older transportation systems that do not yet support AES on the reader side, still leaves an open door to attacks. Though it helps to mitigate threats from attacks that broke the Crypto 1 cipher through the weak random number generator, it does not help against brute force attacks and cryptoanalytic attacks. During the transition period from MIFARE Classic to MIFARE Plus where only a few readers might support AES in the first place, it offers an optional AES authentication in Security Level 1 which is in fact MIFARE Classic operation. This does not prevent the attacks mentioned above but enables a secure mutual authentication between the reader and the card to prove that the card belongs to the system and is not fake. In its highest security level SL3, using 1. AES encryption, MIFARE Plus is secured from attacks. MIFARE Plus EV1editMIFARE Plus EV1 was announced in April 2. New features compared to MIFARE Plus X include Sector wise security level switching the choice of crypto algorithm used in the authentication protocol can be set separately for each sector. This makes it possible to use the same card with both MIFARE Classic readers with sectors protected by 4. CRYPTO1 keys, Security Level 1 and MIFARE Plus readers with sectors protected by 1. AES keys, Security Level 3. This feature is intended to make it easier to gradually migrate existing MIFARE Classic installations to MIFARE Plus, without having to replace all readers at the same time. ISO 7. 81. 6 4 wrapping the card can now be accessed in either the traditional MIFARE protocol which is not compliant with the ISO 7. APDU format, or using a new protocol variant that runs on top of ISO 7. This way the cards become compatible with NFC reader APIs that can only exchange messages in ISO 7. APDU format, with a maximum transfer data buffer size of 2. Proximity check while the MIFARE Classic protocol tolerated message delays of several seconds, and was therefore vulnerable to relay attacks, MIFARE Plus EV1 now implements a basic ISO compliant distance bounding protocol. This puts tighter timing constraints on the permitted round trip delay during authentication, in order to make it harder to forward messages to far away cards or readers via computer networks. Secure end 2 end channel permits AES protected over the air updates even to Crypto. SL1. SL3 mix mode. Transaction MAC the card can produce an additional message authentication code over a transaction that can be verified by a remote clearing service, independent of the keys used by the local reader during the transaction. MIFARE UltralighteditThe MIFARE Ultralight has only 5. The memory is provided in 1. Cards based on these chips are so inexpensive that they are often used for disposable tickets for events such as the Football World Cup 2. It provides only basic security features such as one time programmable OTP bits and a write lock feature to prevent re writing of memory pages but does not include cryptography as applied in other MIFARE based cards.
