Infineon Offers TPM 2.0 to Strengthen Linux System Security
Published2021.03.26 11:58Infineon Launches OptiGa TPM 2.0 Solution
Support for easy TPM integration into Linux-based systems
The Trusted Platform Module (TPM), which provides high-level security for remote software updates, disk encryption, and user authentication, is an essential component of embedded devices.
Infineon Technologies announced on the 25th that it is offering the 'OPTIGA™ TPM 2.0' solution that includes comprehensive TSS (TPM Software Stack) host software to enable easy integration of TPM into Linux-based systems.
IoT system integrators can enhance the security of connected devices using the Optiga TPM 2.0, which supports Plug & Play (PNP).
Infineon, in collaboration with Intel and the Fraunhofer Institute for Secure Information Technology, has developed open-source software implementing the latest FAPI (Feature API) standard. By integrating TSS-FAPI, even those without expertise in low-level security specifications can reduce source code development time by up to 1/16th. Additionally, industrial device certification according to the IEC 62443 standard can also be easily carried out.
Additionally, the TSS stack has implemented the FAPI specification, recently announced as an international standard by the Trusted Computing Group (TCG), along with related tools and plugins. The TSS stack is open-source software that enables seamless integration of TPM 2.0 into Linux-based systems. It includes Linux software support for device authentication, data encryption, software updates, and remote device management.
FAPI is a general-purpose interface for user authentication, single sign-on (SSO), and email encryption/signing, enabling basic support for the PKCS#11 standard. It also provides default configurations for automated handling of cryptographic functions, system integration, and security mechanisms, following the latest industry best practices.
The Optiga TPM acts as a vault for sensitive data in connected devices, reducing the risk of data loss and production downtime due to cyberattacks. Furthermore, Infineon has been certified by an independent certification body according to Common Criteria (CC), an international guideline and standard developed for evaluating information security products. This verifies the compatibility and interoperability between the TSS stack, which includes the latest FAPI, and the Infineon TPM.
