Automotive secure element for smart key fobs released

Eindhoven, The Netherlands

NXP Semiconductors has released the NCJ37x Secure Element (SE), an automotive-qualified secure microcontroller with advanced cryptographic accelerators and physical built in electrical attack resistance for various security-critical automotive applications such as smart access key fobs, Qi 1.3 authentication or car-to-cloud communication.

The device supports the protocols from the Car Connectivity Consortium (CCC) and its passive NFC ISO 14443-4 interface and highly-secure design approach addresses the needs of next-generation smart fobs combining Ultra-Wideband (UWB), Bluetooth Low Energy (BLE), and passive near field communication (NFC) technologies.

Carmakers are rapidly adopting smartphone access systems and evolving their smart fobs towards the higher security levels and wireless interfaces familiar from the smartphone world. This enables new use cases for smart fobs like having digital keys for several cars stored on the fob, and adding other payment means such as bank cards. To meet these needs, OEMs are looking for an open, multi-solution platform with higher security and flexibility that can accelerate time to market. The new NXP NCJ37x Secure Element works with NXP’s NCJ38x car-side Secure Element and corresponding secure applets. The passive ISO 14443-4 NFC, SPI, and I²C interfaces help enable robust protection against latest attack scenarios and an extended feature set for a broad range of secure in-car applications entering the market requiring the secure processing of sensitive data.

“The NCJ37x supports the digitalisation trends of next-generation access systems with a very high level of security in the industry,” said Rainer Lutz, Director Digital Key & NFC at NXP Semiconductors. “A dedicated smart fob applet compatible with the CCC digital key protocol is the smart choice for designing the next-generation smart fobs. NXP’s NCJ37x is another step towards advancing security in smart connected cars.”
