Optiga TPM future-proofs security with PQC-protected firmware update

Wed, Feb 16, 2022

Addressing the challenges of quantum computing, namely cybersecurity, specifically on the confidentiality of encrypted data and on the integrity of digital signatures, Infineon Technologies has developed the Optiga TPM (trusted platform module) SLB 9672. It says it is a future-proof security solution with a post-quantum cryptography (PQC) protected firmware update mechanism using XMSS signatures.

The PQC mechanism counteracts the threat of firmware corruption by attackers with access to quantum computers and increases long term survivability of the device by enabling a quantum-resistant firmware upgrade path. The standardised TPM provides a foundation for securely establishing the identity and software status of PCs, servers and connected devices, and for protecting the integrity and confidentiality of data at rest and in transit.

Infineon’s latest member of the Optiga TPM family is also claimed to be the industry’s first TPM to offer a firmware update mechanism with a 256-bits key length, along with an additional check based on PQC. This mechanism allows the Optiga TPM SLB 9672 to still be updated even if the standard algorithms are no longer trusted. The design is engineered for improved computing performance and to counteract the effects of corrupted firmware. For example, built-in, fail-safe features enable TPM firmware recovery in accordance with the NIST SP 800-193 Platform Firmware Resiliency Guidelines.

The TPM also provides an expanded non-volatile memory to store new features such as additional certificates and cryptographic keys. Security evaluation and certification are performed by independent bodies according to the Common Criteria and FIPS requirements. The TPM also fully complies with the Trusted Computing Group (TCG) requirements (TPM 2.0 standard version 1.59) and is certified according to the latest TPM 2.0 standard.

The standardised trust base is accompanied by tools to support design activities (e.g., software and demo boards), this TPM enables easy integration with host software. It also supports the latest versions of Windows and Linux.

The chip has an extended temperature range of -40 to +105 degrees C.

Infineon is committed to the long-term availability of Optiga TPM SLB 9672 for a minimum of 10 years and offers tailored support and maintenance through the Infineon Security Partner Network (ISPN).

The Optiga TPM SLB 9672 is available to order now.

Tektronix claims industry first with PCI Express 6.0 test

Wed, Feb 16, 2022

Customers can transition to PCIe 6.0 PAM4 signalling, just weeks after the PCI-SIG (Special Interest Group) released PCI Express (PCIe) 6.0 Base specifications and validation requirements, said Tektronix at the release of the PCIe 6.0 Base transmitter test for oscilloscopes.

PCIe 6.0 is a scalable standard for data-intensive markets such as data centre, artificial intelligence / machine learning (AI / ML) and high performance computing (HPC). It transitions to PAM4 signalling and new error correcting techniques. The Tektronix test therefore includes PCIe 6.0 measurement-specific software, enhanced PAM4 DSP capabilities and noise compensation on the oscilloscope. The Tektronix test is further enhanced by the analysis tools for SNDR and uncorrelated jitter measurements which are both mandated requirements for the PCIe 6.0 standard.

The PCIe 6.0 standard transmitter validation for high performance and data-intensive markets is available worldwide for use with DPO70000SX ATI Performance Oscilloscopes.

Tektronix’s customer, silicon IP provider, Alphawave collaborated with Tektronix for early validation of PCIe 6.0 physical layer designs. “Tektronix was deeply involved in defining the PCIe 64 GT/s measurement methodologies, which enabled our engineers to increase their confidence in meeting this challenging new standard prior to release,” said Clint Walker, vice president of marketing at Alphawave.

Tektronix’s Swapnil Mane, marketing director of wired solutions, agreed: “Our PCIe 6.0 standard test and debug solution easily integrates into the engineers’ workflow for test and debug. With the complexity of PAM4 signalling, our analysis tools make it easier to test their design and ensure it meets the new 6.0 standard requirement with a high degree of confidence”.

The test includes PCIe 6.0 (64 GT/s) standard automated base transmitter running on Tektronix DPO70000SX real time oscilloscopes with 50GHz and above bandwidth. It has enhanced PAM4 DSP capabilities with the Tektronix PAMJET application and support for measurements developed for the PCI Express 6.0 standard including SNDR, RLM, uncorrelated jitter, and pulse width jitter. In addition, instrumentation noise compensation techniques are tailored to individual measurements to achieve the most accurate results, said Tektronix.

Tracealyzer 4.6 is designed for easier porting says Percepico

Fri, Feb 11, 2022

Tracealyzer 4.6 has official support for Zephyr RTOS and Microsoft Azure RTOS ThreadX. The release also includes Percepio’s next generation trace recorder library with improved support for snapshot trace. Snapshot recording allows users to access DevAlert, Percepio’s cloud service for monitoring application code executing in deployed IoT devices.

The trace recorder library is for runtime monitoring that benefits both Tracealyzer and DevAlert, said the company. It is designed to be far easier to port to other software platforms and to allow more efficient monitoring of deployed IoT systems and tracing of multi-core systems. The recorder library features more efficient snapshot recording, where trace data is saved in a ring buffer on the target system, for both Zephyr and ThreadX, in addition to the previously supported streaming recording.

CEO, Johan Kraft said: “Both streaming trace and snapshot trace are now supported in the same solution and use the same trace format, which makes it far easier to maintain and improve. Moreover, this will soon enable us to provide an official SDK [software development kit] for partners and customers that wish to integrate Tracealyzer and DevAlert with their RTOS of choice, or with bare-metal firmware.”

Kate Stewart, vice president of Dependable Embedded Systems, The Linux Foundation, commented: “Tracealyzer support for Zephyr is a very welcome addition to the embedded and IoT ecosystems. The ability to visualise code execution is a key tool for developers working with resource constrained devices to be able to efficiently debug defects and release products”.

Another innovation in this edition is the dynamic legend feature, which improves legibility of Tracealyzer’s timeline views, so users can quickly see which events belong to which process or thread. This is particularly valuable for operating systems such as Linux, where the number of threads can become unwieldy, explained Percepio.

The new Tracealyzer recorder library is now integrated into Zephyr and will be included in the upcoming Zephyr 3.0 release.

Tracealyzer 4.6 is available now from Percepio’s web store and through its worldwide network of distributors.

Percepio provides visual trace diagnostics for embedded and IoT software systems in development and in the field. Percepio Tracealyzer combines software tracing with powerful visualisations, allowing users to visually spot and analyse issues in software recordings during development and testing.

Percepio DevAlert is a cloud service for monitoring deployed IoT devices, combining automatic, real-time error reporting with visual trace diagnostics powered by Tracealyzer. Complimentary evaluation licenses are available for both products.

Percepio collaborates with leading vendors of processors, operating systems and development tools within embedded system and IoT such as Arm, IAR Systems, Infineon, NXP Semiconductors, STMicroelectronics, Renesas Electronics, Wind River Systems, as well as IoT cloud vendors such as Amazon Web Services.

Percepio is based in Västerås, Sweden.
