Introduction

The ECC204 is a member of the CryptoAuthentication product family. The device is targeted for disposable and ecosystem control applications and is intended to be used as a companion device with Microchip or other vendors’ microcontrollers.

Features

• Cryptographic Authentication Device with Secure Hardware-Based Key Storage: Protected storage for private key, certificates, symmetric key or user data
• Hardware Support for the Asymmetric Sign: ECDSA: FIPS186-4 Elliptic Curve Digital Signature; NIST standard P-256 Elliptic Curve Support
• Hardware Support for SHA-256 and HMAC
• Internal Asymmetric Key Generation
• Internal High-Quality NIST SP 800-90A/B/C Random Number Generator (RNG)
• Joint Interpretation Laboratory (JIL) Score for Resistance to Attackers with Attack Potential: High; Evaluated to the standard “Jil-Application-Of-Attack-Potential-To-Smartcards-V3.1”; Achieved through tamper-resistant countermeasures to resist environmental, non-invasive and invasive Fault attacks
• FIPS 140-3 Compliance Mode Configuration Option
