Telemaco 3P integrates on-chip HSM, outperforming general-purpose processors.

STMicroelectronics launches its latest automotive processor with a built-in dedicated security module to protect connected cars from cyber threats and lead the relevant market.

With millions of connected cars already shipped, industry analysis projects that the number will exceed 250 million by 2020. Supported by aftermarket equipment such as on-board telematics devices, Wi-Fi hotspots, Bluetooth devices, and OBD (On-board Diagnostics) dongles, connected cars enable drivers and passengers to enjoy safer, more productive, socially connected, and more comfortable journeys. However, this connectivity can be vulnerable to hacker attacks.

The automotive industry is rapidly addressing security issues to prevent hackers from exploiting these connections, as well as supporting market growth for connected services such as content streaming, location-based support services, intelligent emergency support, and OTA-based remote software updates for vehicle electronic control units (ECUs). Experts recommend that manufacturers provide a multi-layered defense system across vehicle circuitry and software by adopting various technologies, such as building trust in connected devices and securing all connections.

ST is helping to solve these industry challenges by combining security chips proven in global financial and government applications with automotive semiconductor technology that meets key industry safety and quality standards. The new Telemaco3P telematics and connectivity processors (STA1385 and derivatives) are the first automotive microprocessors to integrate a powerful, dedicated, and independently operating Hardware Security Module (HSM), acting like an independent security company that monitors data exchanges and handles message encryption and authentication. This HSM securely verifies the authentication of incoming messages and all external devices attempting to connect, preventing eavesdropping and other security breaches.

By integrating an on-chip HSM, the Telemaco 3P device provides significantly better performance than general-purpose application processors widely used in current connected car systems, which lack dedicated hardware-based security features. This new ST chip is very stable because it offers a temperature rating of up to 105°C, allowing it to be used in places that can get extremely hot, such as directly below or above the loop of a smart antenna.

Antonio Radaelli, Senior Vice President of the Infotainment Business Unit at ST’s Automotive and Discrete Products Group, stated, “To realize the benefits of connected cars, robust security capabilities against cyberattacks are required,” and added, “ST’s new Telemaco3P processor combines ST’s proven hardware security technology with automotive industry standard knowledge to lay a solid foundation for safe and convenient connected vehicles.”
