Caliptra IP and firmware for an integrated Root of Trust block.
Caliptra targets datacenter-class SoCs like CPUs, GPUs, DPUs, TPUs. It is the specification, silicon logic, ROM and firmware for implementing a Root of Trust for Measurement (RTM) block inside an SoC. A Caliptra integration provides the SoC with Identity, Measured Boot and Attestation capabilities.
Caliptra is a project originally incepted at the Open Compute Project (OCP). The major revisions of the Caliptra specifications are published at OCP. The evolving source code and documentation for Caliptra live in this repository within the CHIPS Alliance Project, a Series of LF Projects, LLC.
The Caliptra WorkGroup Technical Charter sets out the charter governing the Caliptra project.
