OPTIGA™ TPM - Trusted Platform Module
Security controllers based on TCG specifications (TPM 1.2 or TPM 2.0) protecting integrity and authenticity of embedded devices and systems
OPTIGA™ TPM (Trusted Platform Module) offers a broad portfolio of standardized security controllers to protect the integrity and authenticity of embedded devices and systems. With a secured key store and support for a variety of encryption algorithms, OPTIGA™ TPM security chips provide robust protection for critical data and processes through their rich functionality.
OPTIGA™ TPM security controllers are ideal for platforms running both Windows and Linux and its derivatives (SLB 9645 product versions for Chrome OS available). Based on Trusted Computing Group (TCG) standards, they support the TPM 1.2 or the latest innovative TPM 2.0 standard.

System health check for network equipment and IoT devices
Today, network equipment and IoT devices face a constant barrage of attacks aimed at exposing vulnerabilities in software and firmware. Worst still, cyber threats have become so sophisticated that conventional defense-in-depth cybersecurity measures may even fail to detect them. Once malware is on a device, it may remain there undetected for long periods as it often works undetected in the background. By the time most users realize they have suffered a data breach, they have actually been under attack for weeks, months, or even years.
A system health check supported by Infineon’s OPTIGATM TPM lets users check that their devices have not been manipulated. The TPM provides a secured identity and storage space for system control mechanisms that may check whether hardware and software are still running as intended. The system notifies the user if it does detect changes, e.g. caused by malware.
When devices start up, the software and firmware are measured by the Linux Integrity Measurement Architecture (IMA) and the results are stored in the OPTIGATM TPM Platform Configuration Registers (PCRs). The measurements can then be retrieved by a remote attestation server to determine the configuration of the device at the time it was booted as well as during runtime. The PCR is protected against being rolled back to a previous value. The attestation server polls a platform at set intervals, verifying either that the PCRs in the OPTIGATM TPM have not changed or that the new PCR values are trustworthy. The PCR values are signed with a private Attestation Identity Key (AIK) to reduce the risk of forgery.
For service providers, this means that their services are stable and reliable, and that devices in their network have been checked for manipulation. OPTIGATM TPM also gives device and system manufacturers an opportunity to access new markets requiring new – and differentiating – levels of security. End users benefit from increased security for their sensitive data while still enjoying the same or an even better user experience.
To facilitate use and integration for device and system manufacturers, Infineon has created a Github repository with documents as well as demonstrator source code.

- Common Criteria (EAL4+) and FIPS security certification
- Flexible integration thanks to SPI, I2C or LPC interface support
- Extended temperature range (-40 to +85°C) for a variety of applications
- Reduced risk based on proven technology
- Fast time to market through concept reuse
- Easy integration into all platform architectures and operating systems (Windows, Linux & derivatives
In a bid to meet rising demand for security, many manufacturers and system providers are looking for customized, easy-to-implement solutions that support rapid design-in and deployment by integrating seamlessly into existing and new computing designs. The Trusted Computing Group (TCG) has defined a range of open, vendor-neutral, global industry standards to support interoperable, Trusted Computing platforms. Trusted Computing aims to detect unauthorized changes to a system based on an established security anchor embedded in a computing device. This is achieved with a dedicated microprocessor to support the secured integration of cryptographic keys into the device. The basic keys stored in the Trusted Platform Module (TPM) are processed and used internally, with all cryptographic functions being protected. Long established in computer designs, Trusted Computing is now moving into a much broader application spectrum across industries as diverse as automotive and industrial automation.
As one of the founding members and key drivers within TCG, Infineon continues to bring the benefits of standardization to its customers. Our aim is to provide you with strong, proven security solutions offering reduced integration effort. You can build on our long-standing expertise and reliability to protect sensitive data, establish strong machine identity and integrity, and support secure authentication by protecting certificates, keys and passwords. Backed by our global support team, we offer a market-leading range of OPTIGA™ TPM products supporting all standard interfaces over a wide temperature range. In fact, we were the first semiconductor player to complement our TPM 1.2 offering with a TPM 2.0 product to support the next generation of embedded Trusted Computing applications. Find out more about our OPTIGA™ TPM family and how our portfolio scales across interfaces, packages and temperature ranges to meet individual application needs.
