[crypto, test] Test timing properties of AES-GCM decryption. Add a test that checks if AES-GCM decryption is constant-time relative to different invalid tags. This helps ensure that an attacker cannot get information about how much of the tag they've guessed correctly. As part of this change, refactor AES-GCM testing so that utilities can be imported by multiple files. Signed-off-by: Jade Philipoom <jadep@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.
