[aes] Add support for multi-cycle S-Box implementations This commit lays the ground work for multi-cycle S-Boxes required for SCA hardening. This is achieved by adding input enable signals as well as output req/ack handshake signals between the cipher core controller and the SubBytes and KeyExpand blocks (both contain several S-Boxes). For the currently implemented single-cycle S-Boxes nothing changes, the newly added signals have static values in this case. 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.
