Infineon's OPTIGA™ Trust X Application Notes Framework

Description

This repository contains a target-agnostic Application Notes Framework for the OPTIGA™ Trust X security chip. It is a basis for other application notes.

Summary

The OPTIGA™ Trust X is a security solution based on a secure micrcontroller. 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, 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)
