However, even if a read range of 100 mm is declared in the technical data sheets, we have found a significantly greater reading distance with the EV2 and EV3 chips. The reading range, it should be remembered, varies according to the size and geometry of the antenna, as well as the power of the RFID reader used.
The EV1 chip has a limit of 28 simultaneous applications, while the EV2 and the EV3 have virtually no limits. In addition to this control, the EV3 chip is also equipped with a new function called Transaction Timer which counteracts Man-in-the-Middle (MitM) attacks, in which a potential attacker delays the conclusion of a transaction by keeping the card powered after it left the legitimate reader device.įinally, EV2 and EV3 chips have a separate encryption key management, based on the applications: this allows the card issuer to provide or sell application areas to third parties for personal use, which can be protected with their own keys without knowing the key main card. This means that the card is able to confirm to the reader that it is actually close to the reader and that it is not a remote data stream from a hacker. In addition, the EV2/EV3 chips support proximity control. In particular, we would like to point out that the evaluation assurance level of the EV2/EV3 chips is EAL5+ level, while that of the EV1 is EAL4+ level. The improved security aspects are different.
To these 4 benefits, EV2 cards have backward compatibility with the previous chips, such as the DESFire EV1 and even older D40. The most significant aspects, in our opinion, are the following: Smart cards with MIFARE DESFire EV2 and EV3 chips have significant advantages over EV1 type cards. Due to its high level of security, the DESFire chip is used for applications such as personal identification, access control (even in military environments), loyalty, micropayments and public/private transport. This type of encryption is considered one of the most secure and inviolable. In fact, the name DESFire refers to the use of DES, 2K3DES, 3K3DES and AES hardware encryption to protect data transmission. Within the MIFARE chip family, it is the top of the range in terms of encryption.
