are mifare classic cards still insecure The encryption used by the MIFARE Classic IC uses a 48-bit key. A presentation by Henryk Plötz and Karsten Nohl at the Chaos Communication Congress in December 2007 described a partial reverse-engineering of the algorithm used in the MIFARE Classic chip. Abstract and slides are available online. A paper that describes the process of reverse engineering this chip was published at the August 2008 USENIX security conference.

However, these countermeasures are rather palliating and inadequate for a cryptographically insecure cipher such as CRYPTO1. Despite a series of attacks, MIFARE Classic is still the world's most widely deployed contactless smartcard on the market. The Classic uses a proprietary stream cipher CRYPTO1 to provide confidentiality and mutual authentication between card and reader.

Mifare Classic has been known to be insecure for a long time. The only way to make this secure would be to store the account value, encrypted, in the data sectors, but it's clear that's not the case here.MIFARE Classic encryption has been compromised; see below for details. [citation needed] The MIFARE Classic with 1K memory offers 1,024 bytes of data storage, split into 16 sectors; each sector is protected by two different keys, called A and B. Each key can be programmed to allow operations such as reading, writing, increasing value blocks .The MIFARE Classic product from NXP Semiconductors has been much maligned over recent years and whilst some of the criticism is well justified by virtue of the inherent security problems, it is by no means the weakest card/RFID in use today. Mifare is not a standard; it's a brand name (trademark). Mifare Standard usually refers to Mifare Classic, which is insecure (cracked). Mifare Plus doesn't necessarily mean better.

The MIFARE Classic product from NXP Semiconductors has been much maligned over recent years and whilst some of the criticism is well justified by virtue of the inherent security problems, it is by no means the weakest card/RFID in use today. Now, a prominent RFID researcher has "developed new attacks defeating" the "most secure static encrypted nonce variant of MIFARE Classic," which is "meant to resist all known card-only attacks."
