Revolutionary Microchip Paves the Way for Unparalleled Network Security
Microchip has unveiled a new device designed to help OEMs (original equipment manufacturers) and their module suppliers simplify automotive network security, cutting costs and speeding up time to market.
This innovative product is the first cryptographic companion device that provides pre-programmed security for the automotive sector. With vehicles now integrating more network connections like Bluetooth, LTE, and 5G, there’s an increased risk of cyber threats, prompting stricter security regulations.
To address these challenges, Microchip introduces the TrustAnchor 100 (TA100), a crypto-automotive security IC. This device supports essential in-vehicle network security features such as secure boot, firmware updates, and message authentication at bus speed, including CAN MAC.
Automotive designers now need to equip their vehicle’s ECUs (electronic control units) with secure hardware to meet modern security standards. Traditional options like single-chip dual-core hardware security module (HSM) devices require significant re-architecting of application software, a process that’s time-consuming and prone to security flaws. While third-party security software can help, it often comes with higher costs.
The TA100 offers a different approach for implementing secure boot and message authentication, and it has already gained approval from several OEMs globally for meeting Evita Medium and Full HSM requirements. The device was developed by analyzing major OEM cyber-security standards, facilitating easier approval processes for tier-one suppliers.
Microchip provides additional support through security specification and request-for-quote review services, helping tier-one suppliers make better project bids. The TA100 simplifies securing code development by offering pre-programmed cryptographic internal application code, reducing risks, costs, and time to market.
It’s tested for strong resistance against attacks by third-party assessments and has multiple certifications including AEC-Q100-1 qualification, FIPS 140-2 CMVP Security Level 2, and Physical Key Protection Level 3. It has scored the highest vulnerability assessment rating of JIL High.
Moreover, it integrates seamlessly with software stacks via Autosar drivers, MCALs, and Microchip’s crypto-authentication library. According to Nuri Dagdeviren, Microchip’s VP of secure products, the TA100 significantly eases the security upgrading of ECUs for automotive OEMs and tier-one suppliers.
Furthermore, the device comes with an available Autosar reference stack and MikroBus compatible socket boards, making it ready for standard automotive production environments. It is available in 8- and 14-pin SOIC packages.
