Automotive security dev kit protects in-vehicle networks from hackers

August 07, 2018 // By Ally Winning
Microchip Technology has announced the company’s CryptoAutomotive In-Vehicle Network (IVN) TrustAnchor/Border Security Device (TA/BSD) development kit.

The tool allows developers to introduce security to networked vehicle systems, starting in areas of priority, with the highest level of protection and without disruption elsewhere. The CryptoAutomotive TA/BSD development kit emulates a secure automotive network node that is configurable to various specifications and industry standards.

The tool demonstrates secure key storage, 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 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 MCUs and firmware by later adding the companion chip the kit emulates. Companion chips will come to the customer preprogrammed and include built-in security measures to provide true hardware-based key protection.

The tool can be used with any ECU, architecture, configuration or bus, providing the flexibility to implement security in existing systems without large-scale redesigns. The companion chip solution requires minimal MCU code updates, resulting in minimal to no impact to existing host MCU functional safety ratings. This approach also removes the requirement for in-house security expertise. The tool provides an online GUI program with pre-configured options.
