The MIFARE DESFire EV1 chip has 8 Kbytes of dynamic memory that is arranged in user-defined application folders and data files. This byte-level layout makes it more difficult to clone data on the chip.

Security

The MIFARE DESFire EV1 contactless chip offers enhanced consumer-friendly system design in combination with security and reliability. It delivers a perfect balance of speed, performance and cost mifare desfire ev1 efficiency. Its open concept allows future seamless integration of other ticketing media such as smart paper tickets, key fobs and mobile ticketing based on NFC technology. It features an on-chip backup management system, mutual three pass authentication and encrypted communication.

The IC features 8 Kbytes of dynamic memory arranged in easy to define application folders and data files. The size of each file can be defined at the time of its creation. Moreover, the IC provides an automatic anti-tear mechanism for all file types and guarantees transaction-oriented data integrity. In addition, a high data transmission rate up to 848 Kbit/s can be achieved.

MIFARE DESFire EV1 is compatible with the existing MIFARE DESFire family and is therefore easily integrated into both new and established systems. It also offers a number of advanced functions such as the NXP-specific Secure Boot and TrustZone. Moreover, it supports the latest AES 128 encryption algorithm which offers superior protection against side-channel attacks.

MIFARE DESFire Light is an ideal solution for account-based systems in which only a limited number of applications are required. Its predefined file system and total available memory of 640 Kbytes makes it a flexible choice for a broad range of uses. Additionally, it offers seamless compatibility with MIFARE DESFire EV2, allowing designers to expand their systems in the future.

Interoperability

MIFARE DESFire cards have interoperability with a wide range of contactless systems worldwide. The chip supports a number of different protocols, making them a good choice for use in public transport schemes or closed-loop e-payment applications. It also supports a variety of security functions, including data encryption on the chip and during communication with the reader. This makes it more difficult for unauthorized parties to intercept information. The EV3 version of the chip is particularly impressive, as it supports up to 1 million read/write cycles, which is considerably more than previous versions.

The MIFARE DESFire EV3 is NXP’s most popular chipset, and it boasts several new features that improve the overall security of the system. Its DESFire Crypto Engine uses DES, 2K3DES, and 3K3DES hardware algorithms to secure transmissions and protect against side-channel attacks. It also has a transaction timer, which helps mitigate man-in-the-middle attacks by ensuring that insiders can’t interfere with the transaction.

The MIFARE DESFire ICs have full ISO/IEC 14443A compliance and are designed for secure, reliable operation in a wide range of environments. They are also backward compatible with MIFARE Classic. They are available in PVC and composite production, with the HID SIO enabled card for LEGIC offering future-proofing by combining multiple credentials into one card. This is ideal for organisations migrating to a new system.

Reliability

MIFARE DESFire cards are designed for use in multi-application systems such as access control, e-government, transportation and closed-loop e-payment applications. They offer fast and highly secure data transmission and flexible memory organization, making them ideal for service providers who wish to build a wide range of solutions for their customers. These cards also offer a number of security features to protect against counterfeiting and data theft.

For example, mifare DESFire EV1 has a unique 56-bit serial number that guarantees card identification, and 3DES encryption to prevent pirated reading or writing of the RFID chip. In addition, it has a backup management system that allows the user to store up to 28 different applications on one card and 32 files per application. It also supports a rotating set of access keys, so that users can change their passwords without needing to reissue the card.

The MIFARE DESFire EV1 chip is built on open global standards for both the radio interface and cryptographic methods, making it compliant with all four levels of ISO 14443A and uses optional ISO 7816-4 commands. Additionally, it offers a higher operating distance than MIFARE Classic and is more resistant to interference from other RFID devices in the same vicinity. It also offers a number of security features to protect against fraud, including the ability to detect when the card is close to an access reader and encrypts data at a hardware level using DES, 2K3DES and 3K3DES cryptographic accelerators.

Flexibility

MIFARE DESFire EV1 cards can be used in a variety of different applications and offer a high level of security. The chip’s diversified key encryption feature protects the data transfer between the card and reader, and the hardware security measures prevent unauthorized access to the secret keys. Additionally, a unique authentication message can be generated when the card is tapped, making this product secure and reliable.

The MIFARE DESFire EV1 card is designed for diverse applications that require the highest levels of security, including access control and biometric identification, cashless vending, public transportation, ticketing, and customer loyalty cards. The IC is fully near mifare desfire ev1 field communication (NFC) compatible and can support multiple applications on the same card. The EV1 is also capable of handling large amounts of data with its on-chip backup management system. It also supports up to 28 different applications and 32 files per application, allowing users more flexibility than previous models.

MIFARE DESFire EV1 Light is a limited-use NFC IC that provides an excellent value in both single-user and multi-user applications. It offers a variety of pre-defined protection mechanisms that have been externally reviewed, tested, and certified to Common Criteria EAL4. When tapped, this IC produces a unique tap-unique NFC code that is built on a cipher-based message authentication coding (MAC) algorithm. This feature provides a high level of security that is not available in other NFC ICs.
