The number of Internet cars on the road has reached millions, and industrial analysts predict that by 2020, the total number of Internet cars will exceed 250 million. Post-installation market equipment such as in-vehicle information service controllers, Wi-Fi hotspot terminals, automotive Internet services supported by Bluetooth® devices, and on-board diagnostic (OBD) interface controllers can improve vehicle safety, rider efficiency, and social entertainment . On the other hand, this networking function also provides a real attack surface for hackers.
Auto companies are quickly looking for security measures to support the development of Internet services such as content streaming, location-based assistance, smart emergency rescue, and in-vehicle electronic control unit (ECU) software over-the-air in high-value markets, while preventing hackers from taking advantage of these The networking function achieves its purpose. Security experts recommend that car companies adopt various security technologies, such as establishing a trust mechanism on networked devices, protecting the security of all connection points, and building multiple security lines from the circuit to the software.
STMicroelectronics is helping the automotive industry address these challenges and challenges by integrating its security chip technology expertise in global financial government applications with semiconductor products that meet important automotive industry safety and quality standards. The new Telemaco3P in-vehicle information network processor (STA1385 and its derivatives) is the market's first automotive microprocessor to integrate a powerful isolated dedicated hardware security module (HSM), like an independent security guard, capable of guarding data exchange. , perform information encryption verification function. The HSM module is responsible for verifying the authenticity of the information received by the car and the authenticity of the external device attempting to connect to the car to prevent network eavesdropping.
With on-chip HSM modules, the Telemaco 3P processor is the leading general-purpose application processor commonly found on Internet car systems because these general-purpose processors lack the security features of dedicated hardware. ST's new products are extremely reliable and robust, with a maximum rated operating temperature of 105 ° C, suitable for installations where the ambient temperature may be extremely high, for example, in smart antennas that can be mounted directly above or below the roof. .
Antonio Radaelli, director of infotainment at STMicroelectronics Automotive and Discrete Devices, said: "Internet cars require strong cyber attack defense capabilities, and our new Telemaco3P processor integrates ST's market-proven hardware security technology and Our knowledge of automotive industry standards and requirements has laid a solid foundation for the development of safe and interesting Internet vehicles."
The new automotive processor is part of ST's integrated product strategy, which provides products with built-in security features, including a stand-alone security unit (ST33) and an embedded flash microcontroller (SPC5).
STMicroelectronics will provide STA1385 engineering samples to major partners from now on, and plans to begin mass production in mid-2018.
Technical Description:
In addition to implementing advanced security technologies such as symmetric and asymmetric cryptographic algorithms, the HSM module also runs software security algorithms that reduce the load on the high-performance main CPU, allowing it to handle more complex applications more freely.
On-chip CAN FD (Variable Data Rate Controller Area Network), Gigabit Ethernet and 100Mbit/s Secure Digital I/O (SDIO) interfaces make the Telemaco 3P Series a vehicle communication gateway for connecting infotainment The system or an electronic control unit (ECU) connected to the CAN bus, for example, a door controller, an engine or transmission management system or a body electronic control module. The new processor also integrates basic power management circuitry, which helps simplify design, reduce application size, and save on bill of materials.
The STA1385 complies with the ISO 26261 automotive functional safety standard and meets the requirements of the Integrity Level Standard B (ASIL-B) and complies with the AUTOSAR CAN bus communication protection specification. The Telemaco3P processor supports POSIX-compliant operating systems, giving users the flexibility to choose the best operating system for each target use case.
