There are 3 crates excluded from the Rust workspace: `qos_system`, `qos_aws`, and `init`. These crates are excluded because they only build on Linux. If you are not working directly with these crates they generally only need to be updated if the dependencies for `qos_core` change. The linux only crates each have their own lockfile and that will need to be up to date for deterministic builds to work. To update the locks files you will need a linux build environment. Once in a linux build environment you can run `make build-linux-only`, which updates lock files if necessary; any updated lock files should then be committed. + +## Platforms | Platform | Target | Status | Verified boot Method | |----------------------------|:-------:|:--------:|:---------------------:| | Generic/Qemu | generic | working | Safeboot or Heads | -| AWS Nitro Enclaves | aws | building | Nitro attestation API | +| AWS Nitro Enclaves | aws | working | Nitro attestation API | | GCP Confidential Compute | gcp | research | vTPM 2.0 attestation | | Azure Confidential VMs | azure | research | vTPM 2.0 attestation | -## Features ## +## Components - * Immutability - * Root filesystem is a CPIO filesystem extracted to a RamFS at boot - * Minimalism - * < 5MB footprint - * Nothing is included but a kernel and your target binary by default - * Sample "hello world" included as a default reference - * Debug builds include busybox init shim and drop to a shell - * Determinism - * Multiple people can build artifacts and get identical hashes - * Allows one to prove distributed artifacts correspond to published sources - * Hardening - * No TCP/IP network support - * Favor using a virtual socket or physical interface to a gateway system - * Most unessesary kernel features are disabled at compile time - * Follow [Kernel Self Protection Project](kspp) recommendations +### Enclave -[kspp]: https://kernsec.org/wiki/index.php/Kernel_Self_Protection_Project +- houses server for listening to the Host +- contains logic for quorum key genesis, booting, and running a Enclave App +- see crate [`qos_core`](./src/qos_core/) -## Trust ## +### Host -The main branch of this repo, which contains all binaries in the dist -directory, should always be signed by multiple people who have confirmed the -source code is what they expect, and results in the expected binaries via -reproducible builds. +- EC2 instance housing the nitro enclave +- has client for talking to nitro enclave +- has server for incoming request from outside world +- see crate [`qos_host`](./src/qos_host/) -We use [git-sig][gs] for this. +#### Client -Please install it in order to follow our signing and verification steps. +- anything making request to host +- see crate [`qos_client`](./src/qos_client/) -Two libraries you may need to `brew install` first are `bash` in order to get to version 5+ and `gnu-getopt`.
