Open source software stack eases security integration, says Infineon

Trusted Platform Modules (TPM) enable secured remote software updates, disc encryption and user authentication in connected embedded devices in industrial and automotive applications. Infineon provides its Optiga TPM 2.0 software stack to facilitate seamless integration in Linux-based systems. The TPM software stack implements the latest feature application programming interface (FAPI) standard. Infineon has developed the open-source software jointly with Intel Corporation and Fraunhofer Institute for Secure Information Technology (SIT).

According to Infineon, using the Optiga TPM 2.0 allows IoT system integrators to “significantly improve” the security of connected products. Software integration with TPM software stack (TSS) -FAPI does not require specific skills in low-level security specifications and reduces source code development by a factor of up to 16, claims Infineon. This can result in reduced time to market as manufacturers can accelerate the process for certifying industrial devices according to the IEC 62443 standard for industrial applications, which requires hardware-based safety from level 4 upwards.

The FAPI specification was released as an international standard by the Trusted Computing Group (TCG). The specification is implemented in the TSS stack 1 with the associated tools and plug-ins. The TSS stack is open source software, which allows seamless integration of the TPM 2.0 in Linux-based systems. This includes the support of typical Linux software for device authentication, data encryption, software updates and remote device management.

The FAPI enables the native support of the PKCS#11 standard as a generic interface for user authentication, single sign-on and email encryption/signing. The FAPI provides a default configuration for cryptographic functionalities, system integration and automated processing of security mechanisms, says Infineon.

The Optiga TPM acts as a vault for sensitive data in connected devices and lowers the risk of data and production losses due to cyber attacks. Infineon’s TPMs are certified by independent certification bodies according to the Common Criteria, an international set of guidelines and specifications developed for evaluating information security products. The TSS stack including the recent FAPI has been verified to achieve compliance and interoperability.

Application developers can use the Optiga TPM SLB 9670, Optiga TPM SLI 9670 and Optiga TPM SLM 9670 Iridium boards and TSS Quickstarter now. There are also board and source code packages for the Infineon Aurix and for the Arduino microcontrollers.

Emulator accelerates EV development for international markets

A smart charging station emulator from dSpace allows for the emulation of charging stations with a power of up to 85kW. According to dSpace, the emulator can accelerate the development of electric vehicles (EVs) for international markets.

The Smart Charging Station Emulator allows for the emulation of charging stations with a power of up to 85kW. Manufacturers of EVs and suppliers of battery systems can realistically test new developments with different technical charging standards and protocols, simulate a large number of faults, and develop them quickly and efficiently in line with the requirements of international markets, says dSpace.

It is based on dSpace’s Smart Charging Solution, which is used for testing onboard chargers, charging stations, and communication modules. Other components of the Smart Charging Station Emulator include a Scalexio real-time simulator, a dynamic and expandable model that runs on the simulator. There is also a power supply that enables DC charging and discharging at a maximum of 85kW. This means that vehicle-to-grid (V2G) scenarios can also be simulated, confirms dSpace.

All components are contained in a robust rack, fitted with wheels, to make the system flexible and mobile. It can be used not only in the laboratory but also for tests on prototype vehicles in workshops. There is automatic cable recognition, connecting communication and charge release, insulation monitoring and emergency stop switches, for operator safety.

The system supports international standards for charging communication such as ISO 15118 and DIN SPEC 70121, GB/T 27930, GB/T 18487, and CHAdeMO, and emulates a variety of charging stations and charging scenarios in real time. New charging standards such as CHAdeMO 3.0 or ChaoJi can be implemented.

The Smart Charging Station Emulator supports AC charging up to 63A and DC charging up to a maximum of 200A or 85kW. It is also adaptable to customer-specific charging supply requirements. In addition, the system offers almost unlimited options for manipulating electrical parameters and communication.

dSpace provides simulation and test solutions for developing networked, autonomous, and electrically powered vehicles.
