top priority for both the European Union and the United States.
In Europe on April 25 2022 a consortium of German world-class leaders and market drivers from industry and science combined their forces, launching the Battery Pass to support EU circular battery data. A technological feature of the project is the provision of a comprehensive solution for securely sharing information and data across different organisations and value- chain participants in the
lithium-ion and next generation batteries, including the critical raw materials segments. Bolstering the clean energy economy and strengthening the battery value chain is a
field of traction batteries, based on mandatory standard datasets and an interoperable technical implementation approach required to meet the EU regulation.
In the USA in October 2022 the GBA announced a major milestone with the publication of the Greenhouse Gas rulebook as the first indicator for the Battery Passport, consisting of: A global reporting framework to govern rules around measurement, auditing, and reporting of ESG parameters across the battery value chain. A digital ID for batteries containing data and descriptions about the ESG performance, manufacturing history, and provenance as well as advancing battery life extension and enabling recycling. Harmonizing of digital systems collaborating across the value chain to report data into the battery passport. A digital platform that will collect, exchange, collate and report data among all authorized lifecycle stakeholders to advance a sustainable value chain for electric vehicle (EV) and stationary batteries. It will transparently report progress towards global goals along the battery value chain to inform policy-making for governments, the civil society, and to develop performance benchmarks (Figure 03). A quality seal for batteries (based
on the data reported into the platform) to facilitate responsible purchasing by consumers.
Those examples are reflecting the high engagement from the battery industry to finalize the implementation of the DPP, which will be used as a business model for other power electronics industries.
What is the next step for DPP and power electronics?
As for the battery industry, in 2017 POWERBOX (PRBX) participated in a Think Tank about the future evolution of the power supply industry to reduce waste and to become part of what at that time was a project, the Regulation on Ecodesign for Sustainable Products. In a White Paper: ‘Will the power supply industry adopt the cradle-to-cradle business model?’ PRBX shared ideas on what could become the norm (Figure 04). We are probably a few years away from the power supply industry adopting the DPP, though this is something to keep in mind and it could happen faster than we may believe. Be ready for it!

Latest DICE specification from TCG offers interoperability and user-friendly implementation
Vendors can deliver enhanced security for devices and components thanks to the latest DICE specification from the Trusted Computing Group (TCG) which is currently out for public review.
T
he new DICE Protection Environment (DPE) specification has been developed to offer isolation for sensitive operations and data, reduced code size,
and greater interoperability for DICE implementations. The DPE also provides a path for silicon vendors to create and market strong DICE Intellectual Property (IP) blocks, vastly simplifying the integration of DICE hardware Root-of-Trust (RoT) technology across solutions.
“Handling secrets has historically been done by a vendor’s own firmware unless you had a Trusted Platform Module (TPM),” advised chairman of the DICE Work Group, Dennis Mattoon. “But for devices and components without a TPM, DICE - together with the new DPE specification - can provide isolation and protection guarantees like a TPM. In addition, the DPE specification

provides vendors greater interoperability and a path to marketing discrete DICE implementations that can be integrated across solutions.”
When implementing RoT hardware such as DICE, vendors are given a number of different options for implementation. For organizations who may not fully understand
Components in Electronics
the requirements needed for their products, this can lead to errors in implementation as well as interoperability concerns. At the same time, working with asymmetric keys can also often be expensive, and having the firmware be responsible for cryptography can be a hinderance. The DPE specification enables these operations to be handled
separate from the firmware, freeing up a device’s main processor to focus on firmware activity, with no requirement to generate or handle keys at the expense of performance.
DICE DPE provides isolation for sensitive operations and data, beyond the reach of firmware. This also means greater protection when transitioning between boot layers, hardening attesting environments, and strengthening the chain of trust in devices. The effect is not only a reduction in code size and increased interoperability for existing DICE solutions, but also a substantial reduction in the barrier to entry for organizations looking to adopt a strong hardware RoT in their solutions.
