 Hi and welcome. I'm Eleanor and I'm here at CCOM 2023 to show our ST Microelectronics reference design for secure car access using a mobile phone. This implementation follows the digital key specification published by the CCC or Car Connectivity Consortium, a global working group composed of car and mobile phone OEMs but also silicon vendors. The resulting digital key specification defines how to manage several use cases, such as car and mobile phone pairing, car access using a mobile phone and friend key sharing. The digital key specification ensures interoperability, meaning that different cars can work with different phones. Let's dig into our reference design. I mentioned secure car access, so on the vehicle side we have the STSafe VJ100 CCC secure element. The STSafe VJ100 CCC product is based on the ST33K automotive grade and common criteria EAL6 plus security certified hardware. On top of this certified hardware there is an open java card OS on which specific applications can be developed. Here, an example dedicated CCC digital key application developed by Geerzecker and Deverient is running, but the standard open java card OS can also support other CCC applet implementations. The STSafe VJ100 CCC product can be updated over the air. The STSafe VJ100 CCC is connected via SPI to an automotive host microcontroller the SPC58 which is running the digital key client. On the vehicle side we can also find the ST25 automotive grade NFC reader inside the car door handle. Near field communication will be used to interact with the mobile phone. On the phone side there is an ST54 chip which combines a secure element and an NFC controller. I have previously paired my phone and my car so now if I approach my phone to the NFC reader we can see a mutual authentication happening between the secure elements inside the phone and inside the car. Once the car has recognized the phone the door can be opened. End-to-end confidentiality and integrity are ensured here. No sensitive data such as the digital keys ever leave either of the tamper proof secure elements and the transaction integrity is ensured by cryptographic signatures. I have shown you an example authentication via NFC but the same transaction can also be done via Bluetooth flow energy leaving the NFC as a backup solution. The user can then be authenticated from a greater distance and without needing to manipulate their phone. For this longer distance authentication Bluetooth flow energy is coupled with ultra-wideband technology. Four or more ultra-wideband anchors can be positioned inside the car and one can be positioned inside the phone. This way the vehicle is able to precisely triangulate the user's position via secure ranging sessions. Here the ST Safe VJ100 CCC can provide symmetrical session keys to encrypt the ranging communication. This precise positioning is used for comfort reasons such as opening or closing the door when the user enters a certain range but also as a countermeasure to any relay attacks as an ultra-wideband distance measurement is based on time of flight and therefore cannot be faked. That's all we have time for today. To summarize this was a presentation of our CCC digital key reference platform and of the ST Safe VJ100 CCC a multi-application product able to secure car access and ranging sessions.
