StealthMem Architecture

StealthMem Architecture Diagram

Comprehensive memory encryption with AXI bus mastering and hardware-based key management

Key Features

Comprehensive Memory Protection

StealthMem encrypts and authenticates memory reads and writes in real time, supporting RAM, flash, and NVMe interfaces. Designed to protect software and sensitive data from physical attacks and reverse engineering.

Verified Side-Channel Resistance

StealthMem leverages the verified countermeasures from StealthAES, tested with over 1 billion operations and validated using both TVLA and template attacks. Secure key storage and non-deterministic data paths ensure your keys and plaintext remain protected.

High-Performance AXI Bus Mastering

With full AXI master capabilities, StealthMem interacts directly with system memory, minimizing latency and CPU overhead. Fully compatible with AXI4 and AXI4-Lite interconnects for seamless integration into your existing architecture.

Hardware-Based Key Management

Integrated secure key vault with hardware-enforced access controls enables flexible key rotation, secure storage, and cryptographic isolation across different memory regions and security domains. Keys are securely loaded and decrypted for non-volatile memories, ensuring protection throughout the entire key lifecycle.

Scalable Performance

StealthMem is available in multiple configurations optimized for area, performance, or power, depending on your memory bandwidth and latency needs.

Authenticated Encryption

Combining confidentiality, integrity, and authenticity in a single solution prevents both data exposure and tampering attacks on your critical memory assets.
