The MIFARE DESFire EV1 offers a perfect balance of speed, performance and cost-efficiency. Its open concept also allows for future seamless integration of other ticketing media, including key fobs, Combiwatch and mobile ticketing based on Near Field Communication technology.
These cards are designed to help organizations improve security and maximize value from their existing HID proximity technology access control systems. They feature high security, including 128 AES encryption and compliance with global standards for air interfaces and cryptographic methods.
Security
The DESFire EV1 chip from NXP Semiconductors offers security features to protect data and the user. It is an ISO 14443A RFID transponder that comes with an AES cryptographic engine and supports a variety of encryption methods. Its hardware infrastructure is Common Criteria EAL 5+ certified, which means that it provides high levels of protection from man-in-the-middle attacks and other spoofing techniques. It also has transaction time to prevent interference during a transaction and on-chip back-up management for applications.
The EV1 chip has a unique 56-bit serial number and offers a wide range of application-specific security provisions, including mutual authentication, AES 128, and DES and triple-DES data encryption. It also supports a smart card secure read/write function, which makes it a good choice for multi-functional memory applications. The EV1 chip can support up to 28 applications and 32 files per application, which allows it to accommodate large amounts of data.
The EV1 chips are compatible with all NFC devices, including smartphones, wearables and wristbands. They can be used for contactless applications, such as public transportation, ticketing, and customer loyalty cards. They can also be used with HID proximity technology systems, enabling organizations to add a variety of applications to their existing smart card investments. The EV1 chip is also backward-compatible with MIFARE DESFire EV2, which can allow institutions to upgrade to a more secure solution later.
Interoperability
The DESFire EV1 chip is compatible with many existing systems in government facilities and provides a cost-effective solution. It is also a reliable choice for transportation and ticketing applications, delivering fast and reliable operation in turnstiles and other high-volume environments. Its secure key encryption provides a layer of protection to mitigate man-in-the-middle attacks.
The MIFARE DESFire EV1 256B (MF3ICD(H)Q1) is NXP’s future proof entry level product in the MIFARE DESFire family and is designed to address applications with low memory needs, while still providing the same security and data integrity features as the higher-memory MIFARE DESFire family members. This product utilizes a hardware crypto coprocessor for either 3DES or AES to encrypt transmission data between the card and reader.
It meets the requirements for fast and highly secure data transmission, flexible memory organization and interoperability with existing infrastructure. It is fully compliant to ISO 14443A’s four levels of standards and uses optional ISO 7816-4 commands. The DESFire EV1 chip has an on-chip backup management system and mutual three pass authentication, ensuring security and reliability.
The DESFire EV3 chip offers enhanced performance, greater operating distance and transaction speed compared to its predecessors. It is compatible with a variety of systems and supports a number of open crypto algorithms including DES, 2K3DES, 3K3DES and AES. It also supports a Transaction Timer feature that can be used to set a maximum time per transaction to mitigate man-in-the-middle attack.
Flexibility
A DESFire EV1 contactless chip has the flexibility to combine and support multiple applications, such as access control, payment at vending machines, event ticketing, and loyalty services. This allows universities to implement a single card solution that will work across all of their existing applications, reducing cost and making it easier for students to use their ID.
Another benefit of DESFire is its ability to handle more read/write cycles than previous generations of NFC chips. The EV3 chip, for example, supports 1 million cycles. This is a significant increase from the previous maximum of 500,000 cycles, and it shows that DESFire is an enduring technology that continues to improve with each new generation.
In addition to its flexibility, DESFire also provides excellent speed and range. The EV2 chip, for instance, offers transfer rates of up to 848 Kbit/s, making it one of the fastest NFC technologies available today. It is also backwards compatible, meaning that a solution developed for one generation of DESFire will still work with older systems.
Another reason for DESFire’s popularity is its security. The IC’s hardware cryptographic engine desfire ev1 enciphers transmission data, protecting the user against unauthorized read and write operations. It is a great choice for public transportation ticketing and other closed-loop payment solutions, where high levels of security are required. In addition, it is Common Criteria EAL4 certified, allowing it to be used in legacy terminals.
Cost
The DESFire EV1 chip from NXP offers an ideal solution for users who want more security and flexibility than traditional contact smart cards. It provides the perfect balance of cost efficiency and performance for a wide range of applications. Its secure operating system uses an on-chip backup management system and mutual three pass authentication to prevent unauthorized access to the chip.
The NXP DESFire EV1 chip also includes a hardware cryptographic engine for protecting transmission data. This helps to ensure that the data stored in a card cannot be intercepted, manipulated, or read by another device without the correct key. These features make it an excellent choice for secure public transport schemes and access control applications.
In addition to its encryption capability, the chip is designed for multiapplication and can operate with a variety of ticketing systems. Its open concept enables future tailored integration of varied ticketing forms including Keyfob, Combiwatch, and mobile tickets using Near Field Communication (NFC) technology.
The iCLASS MIFARE DESFire EV1 370x credential features 8 Kbytes of dynamic memory arranged in easy-to-define application folders and data files. These are encrypted using the highly secure AES 128 algorithm, assuring that data in a credential is safe before, during, and after it is used. It is also highly durable and can withstand a high level of shock, vibration, and temperature.
