Automotive Processors with Built-in Security Set

STMicroelectronics is leading the race to protect connected cars against cyber threats with its latest au – tomotive processors that feature a dedi – cated, built-in security module.

Millions of connected cars are al – ready on the road, and industry analysts predict there will be more than 250 mil – lion by 2020. Connected services sup – ported by on-board telematics units, WiFi hotspots, Bluetooth® devices – and aftermarket equipment such as on-board diagnostics (OBD) dongles – enable drivers and passengers to be safer, more productive, socially connected, and bet – ter entertained on their journeys. Unfor – tunately, this connectivity builds a real surface of attack for hackers.

Automotive groups are quickly ad – dressing security measures to support growth in valuable markets for con – nected services such as content stream – ing, location-based assistance, intel – ligent emergency support, and remote software updates over the air of in-car electronic control units (ECU), while preventing hackers exploiting the con – nections for their own ends. Experts rec – ommend manufacturers employ a range of techniques, including establishing trust in connected devices and securing all connections, to provide multiple lay – ers of defense throughout the vehicle’s circuitry and software.

ST is helping the industry meet these challenges by combining its exper – tise in security chips – proven in finan – cial and government applications world – wide – and automotive semiconductors that meet important industry safety and quality standards. The new Telemaco3P telematics and connectivity processors (STA1385 and its variants) are the first automotive microprocessors to integrate a powerful, dedicated, isolated Hardware Security Module (HSM), which acts like an independent security guard to watch data exchanges and encrypt and au – thenticate messages. The HSM securely checks the authenticity of received mes – sages and any external devices that try to connect and protects against eavesdrop – ping.

With this HSM on-chip, Telema – co3P devices are ahead of the generalpurpose application processors typically found in current connected-car systems, which lack dedicated hardware-based security. ST’s new chips are also ex – tremely robust, with a 105°C maximum temperature rating for use in locations that can become extremely hot such as on the top or directly beneath the roof in a smart antenna.

“Realizing the benefits of connected cars requires strong protection against cyber-attacks,” said Antonio Radaelli, Infotainment Business Unit Direc – tor, Automotive and Discrete Product Group, STMicroelectronics, “Our new Telemaco3P processors combine ST’s proven expertise in hardware security and knowledge of the automotive indus – try’s standards and requirements to lay solid ground for safe and enjoyable con – nected motoring.”
