With the growth of automotive connectivity to systems within the vehicle and to the outside world through Bluetooth®, 3G, 4G, LTE and more, there is added user convenience but also the addition of numerous ways to maliciously breach a vehicle’s network. The intensity and scope of attacks continue to increase, making the implementation of comprehensive cybersecurity throughout a vehicle a critical design consideration.
To help meet this need for additional automotive security, we have developed the CryptoAutomotive™ Security ICs In-Vehicle Network (IVN) TrustAnchor/Border Security Device (TA/BSD) development kit which enables you to quickly integrate security into existing networks avoiding a costly redesign.
Our processes for designing automotive products have also been UL-certified as compliant to the ISO/SAE 21434: Road Vehicle—Cybersecurity Engineering Standard. This is a demanding specification with 45 security categories, known as work products, each of which specifies a unique set of requirements that encompass all aspects of designing electrical and electronic systems for road vehicles, from ICs and software to firmware and libraries. The ISO/SAE 21434 designation demonstrates that we are dedicated to maintaining high standards in automotive cybersecurity and that cybersecurity is a priority focus throughout our entire organization.
Our automotive-qualified and ISO 26262 functional safety ready dsPIC33C MPT secure DSCs with an integrated off-die secure subsystem, which is compliant with the Hardware Security Module (HSM) architecture, are excellent options for adding robust security to your automotive designs.
To secure the boot firmware of Advanced Driver-Assistance Systems (ADAS), infotainment and other computing systems in a vehicle, the automotive CEC1712 Platform Root of Trust controller is available to be provisioned with a suite of Linux®-based tools.
Reliable Security Solutions
Inside the vehicle, many Electronic Control Units (ECUs) must coexist and interoperate with each other while maintaining the integrity of the passing data. We provide a variety of solutions that work with crypto standards in the cloud and have adapted these to the automotive framework to provide the same certificate, key agreement, authentication and content protection functions, including:
- A means to provide authenticated CAN messages and prevent man-in-the-middle attacks
- Secure boot of ECUs and the addition of secure boot functions to legacy processors
- Flexible implementation of many crypto functions

Cybersecurity Experience
Security is not something that exists purely at a component level. There are many levels where secure processes and technologies must be implemented. With more than 20 years of experience in manufacturing security products, we leverage the hardware-based security developed for other industry sectors to add real physical protection to automotive networks. We have invested in the secure physical implementation of a manufacturing workflow that allows clients’ keys and certificates to be provisioned on our products in our secure facilities for parts that run in phenomenally high volumes. We provide full audit trails, compliance with many industry standards and are prepared to support new schemes evolving in the automotive sector.
Networking Expertise
While vehicles may currently be using a mix of LIN, CAN and MOST technologies, the industry shift to a service-oriented architecture will mean the addition of more and more Ethernet nodes on the cable harness. Microchip has been a leading player in LIN and CAN since its creation and is the number one supplier of automotive Ethernet nodes. Because of this, we understand where the market is, where it’s going and how to best anticipate and meet your needs.
Our automotive-qualified and ISO 26262 functional safety ready dsPIC33C MPT secure DSCs with integrated off-die secure subsystem, which is compliant with the Hardware Security Module (HSM) architecture, are excellent options for adding robust security to your digital power, motor control, wireless power, advanced sensing and control, touch and general high-performance automotive designs. The hardware security features in dsPIC33C DSCs protect against remote digital attacks, and the physical anti-tampering and side-channel attack protections available in the integrated secure subsystem block access to embedded system credentials to provide extra security.
