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). + +* 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. + + +* 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. + + +* 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. + + +* application-aware-signing + A drawing that shows a proposed mechanism with data and command flows + for doing application based (application aware) signing. + + +* 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. + + +* 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. + + +* hsm-keys + A document that includes diagrams that shows proposed mechanisms for + handling keys including managament, protection and migration of + wrapped keys. + + +* 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. |
