[keymgr] remove one cycle drop at op_accept after keymgr_en is off op_accept is low for one cycle when LC turns off KM When it's low, kmac key is switched to sideload key. And this cycle may expose the good sideload key. It's probably not a security issue but scb checks any good key shouldn't be expose at this point. It may be easy to update design so that we don't need to hack scb to skip checking this cycle. Signed-off-by: Weicai Yang <weicai@google.com>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
