Embedded systems power everything from connected insulin pumps to grid infrastructure. Yet the cryptographic foundations for these devices often lag behind evolving threats, compliance demands, and hardware diversity.��

For 15 years, ����TV TrustCore SDK has delivered a purpose-built, production-proven cryptographic engine across billions of devices. Today, we’re making that foundation open source under AGPL v3.��

This isn’t a stripped-down community edition or an experiment. It’s the same full-featured core that’s secured mission-critical systems in regulated industries—and now, it’s yours to inspect, adapt, and build upon.

Inside the architecture

While traditional libraries are designed for general-purpose environments, TrustCore SDK was engineered specifically for embedded realities:��

• C-based, footprint-optimized modules
  • No dynamic memory allocation dependencies��
  • Minimal build-time configuration��
  • NanoCrypto modules for sub-256KB RAM systems��

• Protocol support
  • Full TLS/DTLS 1.3 with optimized handshakes��
  • SSH (NanoSSH) and IPSec/IKEv2 for secure channels����
  • Extensible Authentication Protocol (EAP) and RADIUS support
• Device identity��
  • Immutable X.509 device certificates anchored in hardware��
  • Secure provisioning and enrollment workflows with EST and SCEP

• Post-quantum readiness
  • ML-KEM, SLH-DSA and ML-DSA integrated for early post-quantum cryptography (PQC) adoption

• FIPS alignment
  • Designed for FIPS 140-2 and 140-3 Level 1 compliance readiness����
  • FIPS validation services offered through our partners��

• Hardware integration
  • TPM 2.0, Secure Element, HSM plug-ins via NanoTAP and NanoSMP��

• Broad portability
  • Support for over 70 chipsets and 30+ RTOS environments (FreeRTOS, Zephyr, VxWorks)

In other words: TrustCore SDK is not just “another TLS library.” It’s a complete cryptographic and identity platform, hardened over a decade of real-world deployments.

Why We’re Opening the Source Now

Transparency has become table stakes. Regulators, customers, and security engineers demand verifiable security, not black boxes.

By open sourcing TrustCore SDK:

• You get full auditability into all cryptographic operations.
• You can validate the code for compliance (FDA Cybersecurity, EU CRA, NIST 800-193).
• You can extend or optimize modules for your specific hardware.
• The developer community can contribute improvements, discover issues faster, and advance embedded security collectively.

Open sourcing under AGPL v3 also preserves a clear boundary between:

• Community-driven innovation and evaluation (open source)
• Enterprise production deployment (commercial licensing with full support)

How you can start today

• Module Availability: The initial open source release includes NanoSSH, and we’ll be adding more TrustCore SDK modules in the months ahead.

• Explore the GitHub repository: Review the architecture, modules, and API reference.

• Run a sample build: Compile for your target platform and evaluate footprint.

• Integrate with your device firmware: Use NanoSSL, NanoSSH, or NanoCrypto modules.��

• Request a commercial license: If you plan to deploy commercially or need enterprise support.

TrustCore SDK gives you a tested foundation and the freedom to prove, adapt, and own your security model.
