PROJECT Version: 1.0
Status: Canonical System Architecture
Architect: Joseph Daniel Milnes
1. Abstract
Legacy internet computing relies on the vulnerable premise of local endpoint execution and implicit network trust. Project AEGIS abandons client-side web rendering and unprotected data storage entirely. This specification establishes a three-tier, zero-trust hardware and software topology comprising a lightweight Client Airlock, a headless RISC-V Render Plane running an seL4-enforced unikernel (ObsidianOS), and a hardware-isolated FPGA Vault.
By decoupling pixel presentation from execution and stripping all credential verification away from the compute layer, AEGIS eliminates 100% of stateful client-side malware, rendering network metadata analysis obsolete.

+-----------------------------------------------------------------------+
2.1 Tier 1: The Client Airlock (Endpoint Application)
The Client Airlock is a lightweight, hardened client running locally on the user’s primary workstation or mobile device. It acts strictly as an I/O conduit:
- Input Extraction: Captures raw coordinate vectors (X/Y coordinates, scroll deltas, click states, and raw keystrokes). No local web scripts or external document macros ever execute within the host operating system.
- Chaff Injection: Injects cryptographically randomized noise into the upstream network stream. Outbound traffic is padded to maintain a flat, constant bit-rate, ensuring external ISP sniffers and eavesdroppers cannot infer user activity, typing cadences, or application behavior.
- Bio-Pulse Generation: Derives behavioral and biometric authentication hashes locally using on-device sensor dynamics. The resulting cryptographic seed is packaged into a blind envelope before network transit.
2.2 Tier 2: The Render Plane (RISC-V Compute Core)
The Render Plane is a headless, stateless computing node running on a high-performance RISC-V hardware platform.
- Operating Environment (ObsidianOS): Operates on the mathematically verified seL4 microkernel. Processes run in capability-constrained isolation, preventing unauthorized inter-process communication or hardware privilege escalation.
- Headless Execution: Web browsers, untrusted binaries, and web applications execute entirely within volatile memory spaces inside the Render Plane.
- Pixel Streaming: The graphical output of the headless browser is continuously rendered to a hardware-accelerated video pipeline (H.264/AV1) and streamed over an encrypted channel back to the Tier 1 Client Airlock for real-time display.
- Blind Credential Transit: The Render Plane operates under a strict Zero-Knowledge constraint regarding user authentication. It cannot inspect, log, or decrypt the Bio-Pulse hash or filesystem master keys; its execution memory remains completely ignorant of Vault credentials.
2.3 Tier 3: The Obsidian Vault (FPGA Silicon)
The Vault represents the sovereign storage baseline, managed by a dedicated FPGA controller (e.g., Xilinx UltraScale+ architecture) directly controlling the persistent NVMe array.
- De-Chaffing & Hash Authentication: The FPGA receives the blinded authentication payload, separates the valid Bio-Pulse hash from the chaffed stream at the silicon gate level, and evaluates access against the internal hardware baseline.
- The Iron Heart: A hardware-synthesized AES-256 cryptographic pipeline executes real-time block-level encryption/decryption between the compute boundary and the physical storage media.
- Volatile SRAM Key Management: Active decryption keys reside exclusively in volatile SRAM registers. Keys are never written to non-volatile flash or disk registers.
- Active Tamper Mesh: A physical conductive mesh encasing the hardware enclosure monitors structural integrity. If a physical intrusion, voltage manipulation, or chassis breach is detected, the line triggers an immediate power purge to the SRAM registers, zeroizing all encryption keys in less than 10 microseconds.
2.4 The Optical Isolation Barrier (Data Diode)
The interface between the volatile compute environment and the sovereign storage vault incorporates a physical unidirectional optical link (Data Diode):
- Unidirectional Enforcement: Forward egress is enforced via physical transmitter-only lasers on the compute boundary paired with receiver-only photocells on the isolated receiver line.
- Malware Containment: Even in the event of a catastrophic root exploit occurring within the Render Plane, physics prevents malicious code from traversing backward to exfiltrate raw unencrypted data blocks or compromise physical Vault registers.
3. Software Architecture & Memory Isolation
Monolithic, multi-gigabyte operating system kernels (Linux, Windows) represent massive, indefensible attack surfaces. AEGIS replaces standard kernel layers with a lean, capability-based unikernel.
+---------------------------------------------------------------+
| ObsidianOS Applications |
| (Headless Chromium / WebRTC Streamer / Video Encoder) |
+---------------------------------------------------------------+
| Rust Runtime Layer |
| (Memory-Safe Drivers / Capability Interconnects) |
+---------------------------------------------------------------+
| seL4 Microkernel |
| (Formally Verified / Strict Capability Access Control) |
+---------------------------------------------------------------+
| RISC-V Hardware Silicon |
+---------------------------------------------------------------+
- Formal Mathematical Proofs: The underlying seL4 microkernel features machine-checked mathematical proofs verifying its functional correctness and spatial/temporal isolation properties under all operating conditions.
- Capability Tokens: A process cannot open sockets, read memory buffers, or dispatch instructions to hardware channels without presenting an explicit, unforgeable capability token minted by the security monitor.
- Ephemeral Session Purging: When a user closes an application session or disconnects the Client Airlock, the entire RAM allocation across the Render Plane is completely overwritten with zero-bytes, preventing memory-scraping forensic attacks.
4. Network Security: The Meridian Protocol
Standard TCP/IP leaks critical metadata (packet timings, packet sizes, destination routing). The Meridian Protocol replaces standard transmission methodologies over untrusted networks.
- Constant-Bandwidth Traffic Shaping: Communication links between Tier 1 (Client) and Tier 2 (Render Plane) maintain an unwavering, flat-rate throughput (e.g., constant 15 Mbps).
- Deterministic Noise Padding: When pointer movements or screen updates decrease, the Client Airlock automatically scales synthetic white-noise chaff packets. An external adversary monitoring network interfaces observes an identical, continuous stream of high-entropy noise regardless of actual user interactions.
- Decentralized Relay Meshing: Packets traverse onion-routed paths across peer nodes, stripping origin and destination metadata before ingress to the Obsidian Core.
5. Behavioral Identity: The Bio-Pulse Engine
Static strings, passwords, and traditional Two-Factor Authentication (2FA) tokens remain vulnerable to phishing, intercept exploits, and coercion. AEGIS establishes identity based on continuous human biomechanics.
- Kinetic Micro-Dynamics: The Client Airlock monitors continuous micro-movements, including keystroke flight-times, pointer trajectory acceleration curves, and device gyroscopic resonance.
- Continuous Confidence Scoring: A localized, lightweight machine-learning engine generates a rolling score ($0.00 \to 1.00$).
- Zero-Knowledge Key Seeding: Once confidence exceeds the required threshold, the engine synthesizes the ephemeral Bio-Pulse hash. This hash is packaged and dispatched directly past the Render Plane to the FPGA Vault, confirming access without exposing human credentials to the execution layer.
6. Disaster Recovery: The Phoenix Protocol
To safeguard against catastrophic physical loss, hardware destruction, or localized hardware failure, the system implements threshold cryptography.
- Master Entropy Splitting: The root entropy required to regenerate the Vault’s cryptographic baseline is split into $n$ distinct mathematical shares using Shamir’s Secret Sharing ($k$-of-$n$ configuration, e.g., $k=3, n=5$).
- Laser-Etched Shards: Shards are preserved onto physical, non-electronic media (such as laser-engraved titanium plates) and distributed across independent geographic points of trust.
- Quorum Reassembly: Recovering any $k$ shares into a newly provisioned FPGA node mathematically re-synthesizes the master seed without revealing the keys to individual share custodians.
7. Architectural Validation
The AEGIS Protocol guarantees:
- Complete Decoupling of Display and Execution: Local endpoint devices run zero untrusted web code; all rendering happens in a volatile sandbox.
- Zero-Knowledge Storage Protection: Decryption keys and Vault logic reside exclusively within physical FPGA gate structures, completely isolated from software execution contexts.
- Physics-Enforced Containment: Optical diodes and unidirectional interconnects make unauthorized data exfiltration physically impossible at the silicon layer.
