OPTIGA™ Trust X Software Framework

Quick navigation

Security Chip

Description

This repository contains a target-agnostic Software Framework for the OPTIGA™ Trust X security chip. It is a basis for other application notes. Be aware that this software comes without any security claims and shall be used for evaluation purpose.

Summary

The OPTIGA™ Trust X is a security solution based on a secure microntroller. Each device is shipped with a unique elliptic-curve keypair and a corresponding X.509 certificate. OPTIGA™ Trust X enables easy integration into existing PKI infrastructure.

Key Features and Benefits

  • High-end security controller
  • Turnkey solution
  • One-way authentication using ECDSA
  • Mutual authentication using DTLS client (IETF standard RFC 6347)
  • Secure communication using DTLS
  • Compliant with the USB Type-C™ Authentication standard
  • I2C interface
  • Up to 10 KB user memory
  • Cryptographic support: ECC256, AES128 (via on-chip DTLS client), SHA-256, TRNG, DRNG
  • PG-USON-10-2 package (3 x 3 mm)
  • Standard & extended temperature ranges
  • Full system integration support
  • Common Criteria Certified EAL6+ (high) hardware
  • Cryptographic Tool Box based on ECC NIST P256, P384 and SHA256 (sign, verify, key generation, ECDH, session key derivation)
  • Lifetime for Industrial Automation and Infrastructure is 20 years and 15 years for other Application Profiles
