Automotive security development kit protects in-vehicle networks

OEMs and Tier 1 suppliers can introduce security to networked vehicle systems, prioritising areas, and starting with the highest level of protection without disruption elsewhere, assures Microchip Technology, introducing its CryptoAutomotive In-Vehicle Network (IVN) TrustAnchor/Border Security Device (TA/BSD) development kit.

Claimed to be the security-specific automotive tool in the industry, the CryptoAutomotive TA/BSD development kit emulates a secure node in an automotive network and identifies an intuitive starting point for implementing security. The tool accommodates allows manufacturers to configure the node to conform to various OEM specifications and industry standards. The tool demonstrates secure key storage, electronic control unit (ECU) authentication, hardware-based crypto accelerators and other cryptographic elements. When used with a host microcontroller, it enables designers to implement functions such as secure boot and controller area network (CAN) message authentication, including conversion of CAN 2.0 messages to CAN flexible data rate (CAN-FD) with appended message authentication codes (MAC) when appropriate.

The TA/BSD emulation kit enables OEMs to continue using their existing microcontrollers and existing MCU firmware certified to required safety standards by later adding the companion chip the kit emulates. These companion chips are supplied to the customer pre-programmed and include built-in security measures to provide hardware-based key protection. This add-on approach can deliver significant cost and time-to-market advantages, says Microchip, compared to redesigning the system with a high-end secure microcontroller, which can involve significant re-architecture of the microcontroller firmware to implement secure zones with hardware and software domains.

The tool can be used with any ECU, architecture, configuration or bus, adds Microchip. The companion chip solution requires minimal MCU code updates, resulting in minimal-to-no impact to existing host microcontroller functional safety ratings. No in-house security expertise is required. The tool provides an online graphical user interface (GUI) program with pre-configured options to simplify and facilitate implementation.

The CryptoAutomotive Security ICs TA/BSD development kit (DM320112) is available today.
