As the automotive industry becomes more reliant on independent vehicle decision-making and increased cloud connectivity, the need for automotive security has never been more important. Modern-era automotive security is about more than just securing door locks. Automotive security has expanded to include vehicle authentication, counterfeit prevention of advanced driver assistance system (ADAS) peripherals, and securing data communication to the cloud. With the imminent deployment of mass-produced, battery-powered, and autonomous vehicles, it is vital to take stock of how these technologies could become harmful if they are not correctly implemented and protected. Securing technology for the cars of tomorrow requires AEC-Q100 Grade 1-qualified secure components, both to enhance safety and preserve optimum system functionality.

Automotive Security Solutions
The DS28C40 is an I2C secure authenticator that enhances automotive security by ensuring the authenticity of the vehicle’s peripheral components. This IC can be embedded in any automotive peripheral, such as a camera, sensor, or battery management system. This automotive secure authentication IC uses ECDSA cryptography to verify to the host ECU that the component in which it is embedded is an OEM-compliant part of the system.
The DS28E40 is a secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware-implemented cryptographic engines, the device integrates a FIPS/NIST True Random Number Generator (TRNG), 6Kb of One-Time Programmable (OTP) memory for user data, keys and certificates, one configurable General-Purpose Input/Output (GPIO), and a unique 64-bit ROM identification number (ROM ID).
