After rigorous testing and careful evaluation, NXP's MIFARE DESFire EV1 smart card technology has received Common Criteria certification from the German Federal Office of Information Security. It is the first automatic fare collection (AFC) product to achieve the Evaluation Assurance Level (EAL) 4+ rating for security.
MIFARE DESFire EV1, the world's first fully integrated solution on the market, is already used in many public transportation networks around the world, including New Delhi, Melbourne, Oslo, Seattle, and the Sube-T system in Madrid.
The Madrid public transport network, for example, is one of largest and most complex infrastructure in the world, carrying more than 1.6 billion passengers a year across more than 40 different operators. The network includes urban buses, an underground metro system, and inter-urban trains. Using MIFARE DESFire EV1 for contactless ticketing gives passengers a very convenient way to navigate the entire system, and gives them the confidence of full security.
The Common Criteria certification validates that the promised security features are, in fact, implemented correction, and verifies the claim of providing “high resistance” against attacks. Certification is a stamp of assurance that lets system integrators compare the security quality of similar products on the market. The process also helps define the robustness of the solution over its full product life, from IC production and usage to disposal of the card.
The DESFire EV1 product is the first AFC solution to be protected against both physical and logical security attacks. As part of the independent review, the key security elements of the DESFire EV1, including cryptography, random number generation, and operating system were fully audited to ensure comprehensive protection. Moreover, as this evaluation has been conducted to ensure compliance to the standard Protection Profile for Smart Card ICs (BSI-PP-0002-2001), the product also fulfils security requirements for banking and eGovernment applications.
