- Layer 2: Cryptographic Acceleration & TRNG Core (Hardware AES-128/256 / SHA-256 / ECC P-256): High-throughput symmetric, asymmetric, and lattice post-quantum accelerators coupled with quantum physical entropy harvesting.
- Layer 3: Secure OS & Enclave Isolation Boundary (Arm TrustZone-M / RISC-V PMP Hardware Isolation): EAL6+ verified microkernel executing inside side-channel shielded memory domains with hardware-enforced DMA firewalls.
- Layer 4: Enterprise Key Lifecycle & API Gateway (I2C / SPI / TCG DICE Device Identity Composition): Standardized cryptographic interfaces enforcing dual-control quorum policies, key usage constraints, and remote attestation.
Cryptographic Telemetry & Compliance: Sub-1 mm² (Silicon Area Footprint) | < 5 μA (Standby Power Consumption) | Zeroization (Tamper Response) | SESIP Level 3+ (Security Assurance)
Hardware Isolation & Cryptographic Assurance in EmbeddedHSM
Modern distributed networks demand uncompromising hardware-enforced protection. EmbeddedHSM consolidates physical tamper detection, side-channel shielding, and verifiable cryptographic boundaries into high-assurance silicon modules.
Core Engineering Areas
- Physical Unclonable Functions (PUF) — Leveraging micro-structural silicon variations in SRAM startup states to generate cryptographic keys without non-volatile storage.
- TrustZone & Enclave Partitioning — Configuring memory protection units, peripheral isolation firewalls, and secure interrupt handlers for embedded microcontrollers.
- Zero-Touch IoT Provisioning — Automating device enrollment, mutual authentication, and cryptographic certificate issuance during semiconductor wafer test.
