Its security features include a hardware and software enhanced anti-tear mechanism and an NDEF-compliant secure dynamic message. It is also backward compatible and has delegated key management system.

Security

NXP’s MIFARE DESFire is a highly secure contactless nxp mifare desfire microcontroller smart card IC that offers system integrators and transport operators best-in-class levels of security for touch-free public transportation and logical access control systems. Its DES encryption and on-chip key management system protect against data manipulation or theft of personal information. It also supports various protocols, making it easy to integrate into existing systems and to support future expansions.

The latest version, MIFARE DESFire EV3, sets new standards for security levels. It has a Common Criteria EAL 5+ certified hardware and software infrastructure, along with a range of open crypto algorithms. It also has a transaction timer feature that helps mitigate man-in-the-middle attacks by ensuring that it takes more than one tap for an attacker to interfere with a transaction.

Another important security feature of MIFARE DESFire is its Delegated Key Management system, which allows applications to be added after the product has been deployed in the field without the need for a master key. It also enables the use of a crypto-secure URL for a card, ticket or mobile phone to prevent social engineering attacks such as spoofing or replay attacks.

In addition to these advanced security features, MIFARE DESFire Light is fully backward compatible with older MIFARE DESFire EV2 and EV1 products. It can also operate in an ISO 14443-4 compliant mode and is configured as an NFC Forum Type 4 tag, which makes it feasible to use with all kinds of contactless readers.

Interoperability

The MIFARE DESFire EV2 contactless IC from NXP is ideal for system providers and developers looking for an extremely reliable, scalable and interoperable multi-application card. It is widely used for transport tickets, closed-loop payment at vending machines and access control management. The DESFire platform supports custom tokens for specific transit schemes and can be combined with other applications such as loyalty programs. This allows system providers to offer new services to their customers.

The DESFire EV2 chip is Common Criteria EAL5+ security certified and features multiple encryption algorithms. It also includes proximity check to protect against relay attacks, an on-chip backup management system and a secure messaging mode. Its unique anti-tear mechanism and elliptic curve based “originality signature” ensure data integrity and prevent counterfeiting of digital credentials.

Moreover, DESFire 8K has a high operating distance and fast data transmission speed, making it perfect for a wide range of applications in the transportation and physical access markets. It can even be used with NFC-enabled smartphones and wearables to enable a variety of Smart City services such as ticketing and payments.

The EV2 chip also has a 70 pF option that enables read range optimization for small antenna form factors. This means that existing readers can be upgraded to support DESFire without the need for replacement hardware. This offers a cost efficient solution that enables new applications for physical and logical access as well as ticketing.

Scalability

MIFARE DESFire is the ideal contactless IC for multiapplication smart cards used in public transport schemes, access management or closed-loop e-payment applications. It combines fast and highly secure data transmission, flexible memory organization and interoperability with existing infrastructure. It also enables developers to create custom keys for logical or physical access control and e-payment systems. Moreover, existing readers can be easily upgraded with a firmware upgrade to read these DESFire custom key credentials.

The MF3DICD(H)21/41/81 mifare desfire ipa is the latest member of NXP’s MIFARE contactless IC family and provides improved performance over its predecessors. This IC offers increased operating distance and transaction speed and supports a 70pF input capacitance option for small form factor designs. It is Common Criteria EAL 5+ certified and supports a variety of crypto algorithms for added security. In addition, this chip is equipped with an on-chip backup management system and the mutual three-pass authentication technique to ensure data integrity.

The mifare desfire v3 chip from NXP is the next generation of this popular technology and is ideally suited for smart city services that require high reliability and scalability. Its open concept design allows future-tailored integration of varied ticketing forms including Keyfobs, Combiwatch and mobile phones with NFC connectivity. It is backed by NXP’s MIFARE 2GO cloud service which manages digital credentials and provides secure e-payment and access to features.

Cost
