Open {hardware} specialist ANAVI has introduced an add-on designed to spice up the safety of tasks constructed across the Raspberry Pi household of single-board computer systems: a Trusted Platform Module 2.0 (TPM 2.0) that slots straight onto the general-purpose enter/output (GPIO) header.
“Designed as open supply {hardware}, ANAVI TPM 2.0 is meant for builders, hobbyists, and professionals who require enhanced safety for Raspberry Pi-based tasks,” ANAVI explains of its creation. “It offers a dependable resolution for safe key storage and cryptographic operations, and it may additionally perform as a True {Hardware} Random Quantity Generator (TRNG), providing a high-entropy supply appropriate for security-critical functions.”

The guts of the tiny add-on board is an Infineon Optiga SLB 9672, which implements the total Trusted Platform Module 2.0 specification — the identical specification Microsoft has made necessary for programs working its Home windows 11 working system. Fairly than the standard connector to position it on a desktop or laptop computer PC motherboard, although, ANAVI’s tackle the know-how makes use of a 2×5-pin header to attach it to the GPIO header on any mannequin of Raspberry Pi single-board laptop.
As soon as put in, the TPM communicates with the host over the SPI bus — and makes use of an current TPM gadget tree binary overlay already included within the Raspberry Pi OS Linux distribution, which means that it ought to work with out fuss. The {hardware} design recordsdata, in the meantime, have already been launched on GitHub beneath the reciprocal Inventive Commons Attribution-ShareAlike 4.0 Worldwide license.
ANAVI is planning to launch a crowdfunding marketing campaign for the TPM 2.0 add-on within the close to future, with events invited to enroll on Crowd Provide to be notified when the marketing campaign goes stay.
