A2e Anti-Tamper — Hardware Security Engineering Program

Hardware Security & Anti-Tamper Design for Defense, Space and Commercial

Hardware roots of trust. Secure boot architectures. FPGA bitstream protection. Physical anti-tamper design. Built for programs where adversarial access to your hardware is a threat model — not a footnote.

  • Security designed in at the silicon level — not bolted on at the end
  • DoD anti-tamper requirements and DAL compliance built in from day one
  • Hardware, FPGA, and embedded security under one roof

When the Hardware Itself Is the Attack Surface

When to Use A2e Anti-Tamper

If your contract, program office, or threat model puts hardware security on the table, A2e Anti-Tamper is built for that conversation.

What A2e Anti-Tamper Covers

Comprehensive hardware security engineering across the full stack — from silicon to firmware.

🏗️

Hardware Root of Trust

Secure element integration, TPM integration, and immutable boot anchor architecture — establishing a hardware-anchored chain of trust that software alone cannot provide.

🔑

Secure Boot Architecture

Cryptographically authenticated boot sequences from power-on through OS load — with key hierarchy design, rollback protection, and fail-secure behavior baked in.

FPGA Bitstream Protection

AES bitstream encryption, readback disable, device binding, and key provisioning workflows for Xilinx and Intel/Altera platforms — protecting IP at the bitstream level.

🗝️

Cryptographic Key Management

Hardware-based key storage, secure provisioning procedures, zeroization circuits, and key lifecycle management — designed for production and field operation.

📋

Security Documentation & Compliance

Anti-tamper plans, threat model documentation, and design evidence packages to support program office review, DAL assessments, and security audits.

How It Works

Four phases — from threat model through verified, documented hardware security design.

1

Security Requirements Review

  • Contract AT requirement analysis
  • Threat model development
  • DAL and compliance review
  • Platform attack surface assessment
2

Architecture & Design

  • Root of trust selection and integration
  • Secure boot chain design
  • FPGA protection strategy
  • Tamper detection and response architecture
3

Implementation

  • Hardware security circuit design
  • FPGA bitstream encryption and binding
  • Key management hardware and firmware
  • PCB-level physical protection measures
4

Verification & Documentation

  • Security design verification
  • Anti-tamper plan documentation
  • Program office review support
  • Production provisioning procedure handoff

What Makes It Different

Most hardware security is an afterthought. A2e Anti-Tamper treats it as a first-class design requirement from day one.

⛔ Typical Approach
Security requirements addressed late — after architecture is locked
Software-only mitigations where hardware protection is needed
No formal threat model — security is assumed, not designed
FPGA bitstream left unprotected or protection added reactively
AT documentation assembled after the fact from incomplete design history
🛡 A2e Anti-Tamper
Security architecture defined at program start — not retrofitted
Hardware roots of trust and physical protections engineered in by design
Formal threat model drives requirements from the first design review
FPGA protection strategy integrated with bitstream, layout, and provisioning workflow
AT plan and compliance documentation built alongside the design — not after

Program Results

Representative outcomes from A2e engagements. All results are anonymized per customer requirements.

DAL Met

Delivered a complete anti-tamper design package — hardware architecture, threat model, and AT plan — satisfying program office review for a defense prime on a compressed schedule.

Protected

Implemented FPGA bitstream encryption and hardware key zeroization for a deployed defense platform, eliminating IP extraction risk identified in a pre-program security assessment.

Retrofitted

Assessed and redesigned the security posture of a legacy embedded platform to meet new contract anti-tamper requirements — without requiring a full board respin.

Results vary by program complexity, scope, and customer collaboration. Contact us for a candid assessment of your specific situation.

A Specialized Offering — Built for Programs That Can't Afford a Security Gap

Hardware security done right requires expertise that few design firms offer. A2e Anti-Tamper brings that depth to your program — with the compliance infrastructure to back it up.

🏛️

Compliance-Ready

ITAR-registered, CMMC-certified facility. Your anti-tamper design work happens in an environment already built for sensitive defense programs.

🔗

Integrated Delivery

Hardware security designed alongside PCB layout, FPGA development, and embedded software — not handed off between disconnected teams.

📄

Audit-Ready Documentation

Anti-tamper plans, threat models, and design evidence packages built to support program office review — not assembled under pressure at the end.

If Your Hardware Is a Target — Let's Talk

Anti-tamper requirements don't get easier to address after architecture is locked. The best time to bring in A2e Anti-Tamper is at the start of your program.
