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 ISO/IEC 14443 Type A 13.56 MHz contactless smart card standard. According to MIFARE themselves, 10 billion of their smart card chips and 150 million of their reader modules have been sold. The technology is owned by NXP Semiconductors, which was spun off from Philips Electronics in 2006. ==Variants== The technology is embodied in both cards and readers (also referred to as a Proximity Coupling Device which is suitable to use). The MIFARE name (derived from the term MIkron FARE Collection System) covers seven different kinds of contactless cards: ; MIFARE Classic : employ a proprietary protocol compliant to parts (but not all) of ISO/IEC 14443-3 Type A, with an NXP proprietary security protocol for authentication and ciphering. ; MIFARE Ultralight: low-cost ICs that employ a proprietary protocol compliant to ISO/IEC 14443-3 Type A. ; MIFARE Ultralight C: the first low-cost ICs for limited-use applications that offer the benefits of an open Triple DES cryptography ; MIFARE DESFire: are smart cards that comply to ISO/IEC 14443-4 Type A with a mask-ROM operating system from NXP. ; MIFARE DESFire EV1: includes AES encryption. ; MIFARE DESFire EV2: includes MIsmartApp, Transaction MAC, Unlimited Applications ; MIFARE Plus: drop-in replacement for MIFARE Classic with certified security level (AES 128 based) ; MIFARE SAM AV2: secure access module that provides the secure storage of cryptographic keys and cryptographic functions 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MIFARE」の詳細全文を読む スポンサード リンク
