NXP MIFARE DESFire 8K and EV4 Smart Cards
MIFARE DESFire is the ideal solution for closed-loop ticketing, logical access control and cashless campus solutions. It is a high speed, secure and reliable contactless chip which works well in turnstile environments.
Featuring the latest hardware and software enhanced security features, it is Common Criteria EAL 5+ certified. It is also capable of providing an on-chip backup management system and an anti-tear function to ensure data integrity.
EV1
A production version of GM’s zero-emission Impact concept car, the EV1 was designed to meet California’s zero-emission vehicle requirements. GM leased the cars to customers through limited lease-only agreements. The program was intended to be a real-world engineering evaluation of EV1’s technology and market potential.
The first generation of EV1s was plagued with battery problems and range anxiety. The EV1’s lead-acid battery required three hours to charge and was expensive. Its low-speed driving range of 70 to 90 miles was a major drawback for many consumers. EV1 lessees were also given special tax exemptions and credits, which led to criticism from environmental interest groups and oil companies that wanted to keep the electric vehicles off the roads.
MIFARE DESFire EV1 is a future proof IC, offering security provisions like an on-chip backup management system and mutual three-pass authentication. It has a small memory plot and is designed to support multi-application solutions such as public transport ticketing, loyalty schemes and access control. It also offers an automatic anti-tear mechanism that is important for ensuring transaction-oriented data integrity.
EV2
The DESFire 8K chip is a smart card that is ideally suited for ticketing applications. It is designed for solution developers and system operators building reliable, interoperable and scalable contactless solutions in identity, access control, loyalty and micro-payment applications. It also complies with the requirements for fast data transmission and flexible memory organization.
The chip provides a high level of security with a 3DES or AES hardware cryptographic engine for the enciphering of RFID Card Supplier transmission data. A variety of protection features are built-in, such as a transaction counter and an elliptic-curve based ‘originality signature’. Moreover, an anti-tear mechanism and random ID ensure the highest possible data integrity during contactless transactions.
Moreover, it supports new business models such as a single card for public transport, closed-loop e-payment applications and local loyalty schemes. It also enables logical and physical access control as well as mobile services. The EV2 platform has an open architecture, which allows for development of solutions faster than other contactless technology. This means that a solution developed for one generation of MIFARE can be used with the next, ensuring full interoperability.
EV3
NXP MIFARE DESFire is a Common Criteria EAL5+ security certified smart card IC and fully compliant with NFC Forum Type 4 Tag. It is ideal for many government facilities, research labs and hospitals where a higher level of security is needed to control physical and logical access. It also offers a cost-effective solution for closed-loop payment applications such as theme parks, festivals, universities and cashless campus solutions. It can be programmed with a custom key credential for a variety of different applications, enabling a single card to work on multiple systems without sharing the same data.
EV1 is the future proof entry level member of the MIFARE DESFire family and addresses applications with limited memory requirements. It has the same security, file creation and on-chip management system as higher memory family members, but with a smaller memory plot to accommodate a limited number of application files. It has an automatic anti-tear mechanism and guarantees transaction-oriented data integrity.
Both the Education and Home versions of EV3 come with a full palette of programming blocks. These include action blocks for controlling motors, displaying and highlighting the Brick buttons, flow control blocks (waiting, conditions, loops), sensors blocks, data operations blocks (variables, lists and mathematic operations) and advanced blocks.
Light
The DESFire Light family is ideal for solution developers and system operators to build reliable, interoperable and scalable contactless solutions. The ICs provide fast and highly secure data transmission and flexible memory organization. They are also capable of supporting multi-application smart cards in identity, access control, loyalty and micro-payment applications as well as transport schemes.
The chip includes particular protection mechanisms to power trusted services, such as up to five customer-defined AES 128-bit keys to monitor and manage access rights, and a configurable secure messaging mode for enhanced privacy. In addition, the hardware and software have been externally reviewed and certified according to Common Criteria EAL4.
The DESFire EV3 chip raises the bar in terms of security levels. It features a new transaction timer feature that helps mitigate man-in-the-middle attacks. The EV3 also provides crypto-based message authentication to ensure the integrity of tap-unique information based on a cipher-based SUN code. The IC can also be configured as an NFC Forum Type 4 tag, meaning it can communicate with a wide range of devices equipped with NFC capability, including Android smartphones.
EV4
EV4 is the latest addition to NXP’s proven contactless MIFARE DESFire family. It is the ideal choice for solution developers and nxp mifare desfire system operators seeking to implement multi-application smart card solutions in access, micropayment, loyalty and transport schemes. It is designed to provide fast and secure data transmission, flexible memory organization and interoperability with existing contactless infrastructures. The IC is Common Criteria EAL5+ security certified and fully compliant with NFC Forum Type 4 Tag IC specifications.
AES128 encryption, secure channel-based file transfer and proximity checks help to prevent data theft. In addition, HID DESFire EV3 credentials offer layered security by providing a random UID, ensuring that the chip cannot be linked to any personal data.
If you are having problems opening an EV4 file, it may be because you have the wrong version of the program installed on your computer. You can check this by right-clicking on the file, and selecting “Properties” or “Get Info” from the menu. You should see a message telling you which software application is the correct one to open it.
