I'm new to reading MIFARE Classic cards and wondering how to access each sector with Key A (A0A1A2A3A4A5) and a given Key B (which remains secret).

Every sector has a common structure: 3 blocks of data, and 1 access control block. The access control blocks contain Key A, Key B, and the Access Bits.See (Figure 1.2) The A & B keys can be standard (as in the most commonly used) or unique and set by the tag owner, and the access bits determine the rights on each sectors (read, write, both or none) Note: the Mifare key is composed as follow: 6 byte for key A; 4 byte for Access Bits; 6 byte for key B which is optional and can be set to 00 or any other value; To change your keys you have to authenticate the Sector Trailer and the write your new keys + new access conditions if you want to change them too.

  2. The different sectors of the MIFARE Classic card are protected by different keys. To be able to decrypt the content of the card, the keys must be found. There are two well-known applications for this: mfcuk [6] and mfoc [7]. A typical attack scenario is to use mfcuk to find the first key of the card (which may take quite some time). When one key is found, mfoc can be used to find all other.
  3. There are two keys, each 6 bytes long. Typically Key A is used, but Key B is also possible. The two keys fit into one entry in the SAM AV2.

I am using Mifare Classic 1K. My goal would be to enter the memory of the card with the keys I know (factory default for the first time), write in the sector of my interest, modify key A, key B and the access bits of C1, C2, C3 so that if someone then goes to read the card again (eg. with Taginfo) you cannot read the contents of the sectors or even read C1, C2, C3, but read a series of x for. keys (and of course the access rules must allow that key to be used for that block). The keys should have been supplied by whoever gave you the card. The default keys are either FF FF FF FF FF FF for both, or A0 A1 A2 A3 A4 A5 for key A and B0 B1 B2 B3 B4 B5 for key B. The default access conditions allow everything for key A and nothing for key B MiFare DESFire are iso14443A compliant contactless smartcards, and support all layers including iso14443-4. These cards are so-called stored value cards, so you cannot install and execute your own program code on DESFire cards. DESFire is like a memory card with access control.

The MIFARE card (ISO 14443 A/B compliant) also implements a proprietary (NXP) encryption algorithm known as Crypto1 with 48-bit keys on its MIFARE Classic 1k card. Unfortunately, as is typically the case with creating custom crypto, Crypto1 has since been compromised and is vulnerable to nested and hardnested brute force key guessing attacks.

  6. La tarjeta MIFARE 4K, generalmente está reservada para sistemas de acceso biométrico con tarjeta o con huella digital donde las huellas digitales se almacenan en la memoria MIFARE. Las llaves de seguridad Key A y Key B protegen el acceso a datos y mejoran la seguridad de autentificación en aplicaciones que usan la tarjeta inteligente RFID.

MiFare Ultralight cards typically contain 512 bits (64 bytes) of memory, including 4 bytes (32-bits) of OTP (One Time Programmable) memory where the individual bits can be written but not erased. MiFare Ultralight cards have a 7-byte UID that uniquely identifies the card. Reading and capturing contents of the card. After some investigation I noticed that my Samsung mobile phone has a NFC. Obtain keys. Default keys ; Non-default keys; Dump card content; Write dump to empty card; Obtains keys . Before being able to dump the content of the card, the keys have to be obtained. There are some default keys that manufacturers use and that are never changed. Running fchk with the -dump option will test for default keys and will dump them if successful. Default keys [usb] pm3 --> hf mf. MIFARE Ultralight can be formatted as NFC Forum Type 2 Tag. But MIFARE Plus can't be formatted as NFC Forum Type Tags. So it is not possible to use NFCNDEFReader API for MIFARE Plus. You can use only NFCTagReader API for MIFARE Plus
