AEGISVAULT: Zero-Trust Key Management Architecture
The Architectural Friction (The Problem)
Financial applications handling key signing are prime targets for memory-scraping attacks. Legacy infrastructure often leaves highly sensitive private keys exposed in system memory during high-frequency trading or settlement windows.
The iHexe Execution (The Solution)
This demonstration pairs Rust's zeroize trait with AWS Nitro Enclaves. Cryptographic keys exist only inside a hardware-isolated enclave and are automatically wiped from memory the instant they are not needed. Even a full server-level compromise cannot extract the keys.
Memory Safety: PROVED
KYC Resolution: < 800ms

The iHexe Cryptographic Protocol
Rust HSM Enclave & Memory Safety
Cryptography requires bare-metal speed and absolute memory safety. We extracted the core encryption logic out of the Node.js runtime and re-engineered it as a high-performance Rust microservice acting as a Hardware Security Module (HSM) enclave. This guarantees mathematically proven memory safety (zero buffer overflows) and executes AES-256 encryption in sub-milliseconds.
Agentic Risk Assessment via MCP
AI must be powerful, but blind to PII. We deployed a highly specialized Agentic AI to autonomously flag fraudulent transaction patterns. To protect user data, we architected a custom Python Model Context Protocol (MCP) server. The MCP server sanitizes and anonymizes all transaction data before it ever touches the LLM, ensuring absolute compliance with global financial privacy laws while clearing legitimate trades instantly.
Kafka High-Frequency Event Streams
We eliminated database locks. Instead of writing directly to a standard relational database during a traffic spike, we decoupled the architecture using Apache Kafka. Every trade, KYC event, and AI risk score is published to an immutable, distributed event log, ensuring 100% ledger durability and allowing the Next.js frontend to instantly reflect balances via WebSockets.
