Security Architecture + +**Authentication**: JWT Bearer tokens issued by Azaion Resource API. Tokens decoded without signature verification (trusts the API server). + +**Authorization**: Role-based (RoleEnum: NONE → Operator → Validator → CompanionPC → Admin → ResourceUploader → ApiAdmin). Roles parsed from JWT but not enforced by Loader endpoints. + +**Data protection**: +- At rest: AES-256-CBC encrypted resources on disk; Docker images stored as encrypted `.enc` archive +- In transit: HTTPS for API calls; S3 HTTPS for CDN +- Secrets management: CDN credentials stored in encrypted `cdn.yaml` downloaded from API; user credentials in memory only + +**Key derivation**: +- Per-user/per-machine keys: `SHA-384(email + password + hardware_hash + salt)` → used for API resource downloads +- Shared resource key: `SHA-384(fixed_salt)` → used for big/small resource split encryption +- Hardware binding: `SHA-384("Azaion_" + hardware_fingerprint + salt)` → ties decryption to specific hardware + +**Audit logging**: Application-level logging via Loguru (file + stdout/stderr). No structured audit trail. + +## 8. Key Architectural Decisions + +### ADR-001: Cython for IP Protection + +**Context**: The loader handles encryption keys and security-sensitive logic that should not be trivially readable. + +**Decision**: Core modules (api_client, security, cdn_manager, hardware_service, credentials, user, constants) are written in Cython and compiled to native `.so` extensions. + +**Alternatives considered**: +1. Pure Python with obfuscation — rejected because obfuscation is reversible +2. Compiled language (Rust/Go) — rejected because of tighter integration needed with Python ecosystem (FastAPI, boto3) + +**Consequences**: Build step required (`setup.py build_ext --inplace`); `cdef` methods not callable from pure Python; debugging compiled extensions is harder. + +### ADR-002: Binary-Split Resource Scheme + +**Context**: Large model files need secure distribution. Storing entire encrypted files on one server creates a single point of compromise. + +**Decision**: Resources are encrypted, then split into a small part (uploaded to the authenticated API) and a large part (uploaded to CDN). Decryption requires both parts. + +**Alternatives considered**: +1. Single encrypted download from API — rejected because of bandwidth/cost for large files +2. Unencrypted CDN with signed URLs — rejected because CDN compromise would expose models + +**Consequences**: More complex download/upload logic; local caching of big parts for performance; CDN credentials managed separately from API credentials. + +### ADR-003: Docker-in-Docker for Image Loading + +**Context**: The loader needs to inject Docker images into the host Docker daemon on edge devices. + +**Decision**: Mount Docker socket into the loader container; use Docker CLI (`docker load`, `docker image inspect`) via subprocess. + +**Alternatives considered**: +1. Docker API via Python library — rejected because Docker CLI is simpler and universally available +2. Image loading outside the loader — rejected because the unlock workflow needs to be self-contained + +**Consequences**: Container requires Docker socket mount (security implication); Docker CLI must be installed in the container image. diff --git a/_docs/02_document/components/01_core_models/description.md b/_docs/02_document/components/01_core_models/description.md new file mode 100644 index 0000000..10601d2 --- /dev/null +++ b/_docs/02_document/components/01_core_models/description.md @@ -0,0 +1,98 @@ +# Core Models + +## 1.
