MIFARE DESFire EV1 Cards
Designed to support diverse applications, such as access control and biometric identification, cashless vending, public transportation, ticketing and customer loyalty cards, MIFARE DESFire EV1 cards offer high security through mutual authentication and an on-chip backup management system. This card also provides faster data transmission and more flexible memory organization.
Moreover, it has rolling keysets to prevent relay attacks and staggered key management that lets the issuer share services without sharing the card Master Key.
EV1 vs. EV2
The DESFire chip has a very high level of security using a DES, 2K3DES, or 3K3DES hardware cryptographic engine for confidentiality and integrity protection of the transmission data. It also includes a Transaction Timer feature to help mitigate man-in-the-middle contact smart card attacks by setting a maximum amount of time per transaction, so that an attacker cannot intercept the communication to modify data or make fraudulent transactions.
The newer EV2 chip is more advanced than its predecessor with enhanced performance and cost efficiency. It is fully compliant with ISO 14443A 1-4 and has a Common Criteria EAL 5+ security rating, making it one of the most secure contactless chips on the market. It is much faster than EV1 with transfer rates up to 848 Kbit/s. It also has a 70 pF option that enables read range optimizations for small antenna form factors.
It is possible to upgrade EV1 cards to EV2 by using a third party programmer that supports the MISmartApp (NXP’s implementation of the open protocol). However, it should be noted that not all readers support the EV2 encoding and that there are some EV2 features that can only be enabled on a card if it has EV1 data encoded on it. This is an important consideration if you are planning to use the cards in a new system.
EV2 vs. EV3
MIFARE DESFire EV2 is NXP’s latest addition to the MIFARE family, and it offers a number of benefits over EV1. This new IC has an improved read range that is slightly higher than EV1, as well as the ability to support more applications. It is also backward compatible with EV1, meaning that systems developed for EV1 can be used with EV2.
Mifare DESFire EV2 is an 8Kbyte non-volatile memory, an ISO14443A compliant contactless interface and a high-speed triple-DES data encryption co-processor. It offers a mutual 3-pass authentication technique together with a true random number generator, and it has a anti-tear mechanism to guarantee data integrity during contactless transactions.
It is Common Criteria EAL5+ security certified, which means that it is as secure as the chips in e-passports or banking cards. It also features a Transaction Timer that can be used to mitigate man-in-the-middle attacks. Moreover, it can be programmed using MiSmartApp, which is NXP’s new delegated key management system that allows card issuers to add more services to existing cards without having to share the master key with other third parties.
Other improvements include an enhanced Proximity Check function to detect relay attacks and a Staggered Key Management system that provides additional protection. Additionally, EV3 can be programmed with a 70pF version, which enables read range optimisation for small form factor designs.
EV2 vs. EV4
The MIFARE DESFire 8K is an ideal choice for organizations that are making the transition from magnetic stripe and proximity technology to smart card-based solutions. It is compatible with HID Proximity and can be combined with magnetic stripe or HID RFID reader technologies, providing a flexible migration path that addresses the specific security needs of each facility. The MIFARE DESFire 8K features an eight-kbyte non-volatile memory and a high speed triple-DES data encryption co-processor. It also has a flexible memory organization structure, a mutual 3-pass authentication technique together with a true random number generator and an anti-tear mechanism to guarantee data integrity during contactless transactions.
The DESFire chip is one of the highest-security radio-frequency chips available on the market. It utilizes DES, 2K3DES, 3K3DES and AES hardware encryption to protect data transmission, and it is certified Common Criteria EAL5+. This makes it a great choice for personal identification, access control (even in military environments), loyalty, transportation and closed-loop micropayments.
The EV2 chip is the next generation of the MIFARE family. It provides new security features that help to prevent fraud, including rolling keys, on-chip backup management and mutual three pass authentication. It also has a proximity check feature that helps to protect against relay attacks. It also has faster read and write speeds than EV1 cards. Another advantage of EV2 cards is their longer read range. This can be achieved by using a stronger reader or by improving the design of the antenna.
EV2 vs. EV5
The MIFARE DESFire chip is one of the top RFID chips in terms of security. It uses DES, 2K3DES, 3K3DES and AES hardware encryption to protect data transmissions. These features make it an ideal choice for security-related applications, such as access control and biometric identification, cashless vending, public transportation, ticketing and customer loyalty cards.
The DESFire EV2 IC has many improvements over the older DESFire ICs, including a higher read/write cycle capacity. It also has new security provisions, such as the proximity identification feature that allows the card to confirm it is in range of the reader mifare desfire ev1 before allowing a transfer of data. This reduces the potential for relay attacks. It is also certified to EAL5+, which makes it more secure than other contactless ICs.
In addition, the EV2 IC has increased communication range over the EV1 chip. It is also compatible with a wider variety of readers. Moreover, it has more flexibility than the old DESFire chip. This makes it a good option for upgrading existing HID Prox systems to include DESFire functionality.
HID global offers a multi-technology solution with the MIFARE DESFire EV2 and iCLASS SE (SIO) combined in a single physical credential. These cards are perfect for organizations moving from basic HITAG to DESFire and/or seeking a single-card solution. These credentials offer guaranteed interoperability with HID readers and are backed by the same trusted, fully-interoperable security as all Genuine HID products.
