MIFARE is the name of contactless smartcards or proximity cards made by NXP Semiconductors. They are the leading manufacturer in the world and have sold over 10 million card readers and 1 billion cards. The company is based in Eindhoven, Netherlands but they have several offices worldwide. Their cards and card readers employ several different forms of technologies that range in security, including the original MIFARE Classic (Standard) and the MIFARE Plus.
MIFARE Classic is the standard card sold by NXP and it uses a proprietary security protocol instead of the ISO/IEC 14443-4 that has become popular in recent years for the quality of its security. The MIRFARE Classic is basically only a memory storage device with an embedded chip in the card. There are reliable and inexpensive, holding 1k to 4k of data. The encryption on the MIFARE Classic is basic at best and called Crypto-1. In tests, this card’s encryption has been broken in 12 seconds on a laptop with only 50 bits of known information. Several other attacks have also been exposed that can read or alter the information on both the card and the reader.
MIFARE Plus is NXP’s attempt to remedy the security problems of the Classic card. Released in 2008, the breakthrough security features of the Plus card far surpass those of its predecessor. The MIFARE PLUS has multiple levels of security that include the Advanced Encryption Standard (AES). The heart of the encryption on the MIFARE Plus is the 128-bit AES and is combined with other protocols for confidentiality and authentication. These security features are all brought together with the use of Random Identifiers (RIDs) next to 7 byte Unique Identifiers to provide a maximum of security and peace of mind for both users of the cards and the company providing them.
The general manager of the automatic fare collection division of NXP semiconductors, Henri Ardevol, has stated, “MIFARE Plus offers unprecedented levels of security, privacy, compatibility, and performance for entry-level smart cards, and is ideal for ticketing systems.” He goes on to say, “The IC has been designed from the ground up to address the security and privacy needs of the 21st century and thus complements well our current MIFARE portfolio. With MIFARE Plus, consumers can rest assured that their individual information cannot be tracked by others.”
