<h1>design documentation</h1>

<p>This repo contains a number of documents used during development of
various parts the Cryptech design. Note that the directory contains
source files (for example in OmniGraffle, Open Document file formats) as
well as final documents (normally in PFF file format).</p>

<ul>
<li><p>Alpha_board_drawing
A drawing/diagram that shows the functional components and their
functional connectivities for the Cryptech Alpha board being
developed. The drawing is not formal schematics for the Alpha board.</p></li>
<li><p>Novena-entropy-board
Sub directory with schematics as well as layout with silk screen for
the Cryptech Noise board designed to be used as external entropy
source on the Novena.</p></li>
<li><p>alpha_board_config
Configuration file for setting up the I/Os and functionality of the
STM32 microcontroller on the Alpha board. The config file is used by
the tool [STM32CubeMX][http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/PF259242?sc=microxplorer] from ST Microelectronics.</p></li>
<li><p>application-aware-signing
A drawing that shows a proposed mechanism with data and command flows
for doing application based (application aware) signing.</p></li>
<li><p>fpga_estimates
A document that tracks the FPGA resources and performance of the
different Cryptech cores in different FPGA technologies. The document
also includes estimates for cores not yet designed or completed. The
purpose of the document is to provide estimates of FPGA devices needed
to implement different use cases.</p></li>
<li><p>hsm-board
A high level functional diagram of the Cryptech HSM board that shows
the major functional blocks. Used during development of the Alpha
board to see what components are needed to realise the functionality
of the blocks. The Alpha_board_drawing is the concrete functional
realisation of this diagram.</p></li>
<li><p>hsm-keys
A document that includes diagrams that shows proposed mechanisms for
handling keys including managament, protection and migration of
wrapped keys.</p></li>
<li><p>novena-memory-map
This document contains information about the memory map of the
Cryptech FPGA design with the specific memory maps of each core as
well as how the cores are addressed and accessed from SW via different
interfaces.</p></li>
</ul>
