[aes] Add 2-share implementation of the cipher core for security hardening This commit adds a first version of the first-order masked, 2-share implementation of the AES cipher core. The masking can be enabled via a design time parameter. If enabled, both the cipher datapath and and key schedule are masked. The generation of the masks is not part of this commit but future work. At the moment, constant masks are used. This is of course not secure. Signed-off-by: Pirmin Vogel <vogelpi@lowrisc.org>
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.
