-= Planning for SUNET funded Cryptech Work =
-The following documents the first two development steps in Cryptech
-funded by SUNET. The development is being done by Joachim Strömbergson
-from Secworks AB.
-
-== Step one (Deadline 2014-02-28) ==
- - Acquire a FPGA development platform.
-DONE. We have a Terasic DE0 board and a Terasic Cyclone V GX starter kit board.
-
-
- - Create a working development and verification flow from RTL design
- downto FPGA.
-
- - Verify the functionality of the SHA-256 core in a physical FPGA.
-
-
-=== Actions for step one ===
- - Select FPGA development board to acquire
- - Large enough to test sub systems and possibly a complete HSM.
- - Good external interfaces for communication with host systems.
- - Good external interfaces to entropy sources, memories,
- GPIO. Arduino Shields would be good.
-
- - Create a survey on interconnect standards usable for Cryptech
- - Availability and market share/usage in third party cores.
- - License
- - Technical details - Bus, fabric, performance etc.
-
-
- - Create base coretest functionality to allow testing of cores in the
- FPGA on the development board. Read and write access to registers
- over a known communication channel.
-
- - Verify the development flow from Verilog RTL downto FPGA.
-
- - Verifiera SHA-256 core using coretest.
-
- - Start FPGA tool survey
- - What is available as open tools and what is the status.
- - What is available as open tools from the vendors.
- - Talk to people in the industry to get their views on an open toolchain.
-
-
-== Step two (Deadline 2014-03-31) ==
- - Produce first draft of design proposal to the Cryptech True Random Number Generator (TRNG)
- - Security target, security model and assumptions
- - Structure, architecture
- - API
- - Functionality
- - Online test system
- - Verification model
- - First two entropy sources
-
- - Complete SHA-1 core. Including functional verification in FPGA.
-
- - First draft of SHA-256 and SHA-1 core documentation.
-
-
-=== Actions for step two ===
- - Create template for documentation
-
- - Collect info on known TRNGs and TRNG strategies
-
- - Collect info on online tests being used.
-
- - Create proposal for architecture.
-
- - Write implementation proposal.
-
- - Specify API.
-
- - Write security target and security model.
-
- - Write assumptions and limitations.
-
- - Write verification model.
-
- - Finalize SHA-1 core RTl.
-
- - Build SHA-1 core in FPGA.
-
- - Verify SHA-1 functionality in FPGA using coretest.
-
- - Write documentation for SHA-256 core.
-
- - Write documentation for SHA-1 core.
