Quickly Integrate Security into Existing Automotive Networks with Minimal Design Impact

The Need for Automotive Security is Real

While Bluetooth® connectivity and support for the latest cellular networking technologies have become standard in most vehicles to the delight of consumers, this has also opened up an attractive target for hackers. Many real-world vehicle hacking stories and videos are available on the Internet, and virtually all OEMs in all regions have been negatively impacted by these attacks. Since the attack surface will certainly continue to grow as more connected vehicles hit the road, OEMs and Tier 1 suppliers are facing increasing pressure to find long-term solutions to secure in-vehicle networks.

A New Day in Automotive Cybersecurity

The latest OEM cybersecurity specs require improved security measures including hardware-based secure boot and CAN message authentication. Implementing these new specs can be burdensome for Tier 1 suppliers. The first investigation typically involves switching out their existing host microcontroller (MCU) to a higher-horsepower dual-core 32-bit MCU with crypto. This can introduce significant additional silicon cost, software development expense and design risk in correctly implementing new security software in the MCU.

Industry’s First Automotive Cryptographic Companion Security IC

The TrustAnchor100 (TA100) CryptoAutomotive™ security IC provides a way for you to implement security into existing systems without requiring costly redesigns. The TrustAnchor100 provides external Hardware Security Module (HSM) support for secure boot, CAN message authentication, Electric Vehicle (EV) battery authentication, Transport Layer Security (TLS), Wireless Power Consortium (WPC) 1.3 Qi® authentication, High-Bandwidth Digital Content Protection (HDCP) and more.

Key Advantages

  • Significant cost and time savings compared to redesigning with a new MCU
  • Minimal MCU code updates resulting in little to no impact to existing host MCU functional safety ratings
  • Preprogrammed with built-in security measures to eliminate the need for in-house security expertise
  • Elimination of risk associated with significant MCU code updates
  • More whole-chip tampers with a higher level of certifiability
  • True hardware key isolation

Getting Started Is Easy

Jump-start your application development with our TA100 8-pin SOIC and TA100 14-pin SOIC socket boards. These mikroBUS™ compatible socket boards can be used with the I2C and SPI versions of the TA100 device and can be easily plugged into one of our many development boards that feature a microBUS socket, including the Explorer 16/32 Development Board, the Automotive Networking Development Board and a variety of Curiosity and Curiosity Nano development boards. They can also be used with an mikroBUS Xplained Pro adapter board to connect them to Xplained Pro development boards. Example projects are available to demonstrate sample applications using the TA100. A suite of software tools is also  available under NDA. Contact your Microchip sales office to request access to these tools.
