Product brief
The optimized solution for IoT security
As embedded systems are increasingly gaining attention of attackers, Infineon offers the
OPTIGA™ Trust X as a turnkey security solution for industrial automation systems, smart
homes and consumer devices. This high-end security controller comes with full system
integration support for easy and cost effective deployment of high-end security for your
Broad range of benefits
Integrated in your device, the OPTIGA™ Trust X supports the protection of your brand and
business case, differentiates your product from your competitors, and adds value to your
product making it stronger against cyber-attacks.
Enhanced security
The OPTIGA™ Trust X comes with an advanced security controller built on Elliptic Curve
Cryptography (ECC) with 256 bit, AES128 and SHA-256. This new security technology
greatly enhances your overall system security. Furthermore the OPTIGA™ Trust X covers a
broad range of use cases necessary to protect the authenticity, integrity and confidential-
ity in your device: mutual authentication, secured communication, data store protection,
life-cycle management, secured updates, and also platform integrity protection.
Fast and easy integration
The turnkey set-up with full system integration and all key material preprogrammed
reduces your efforts for design, integration and deployment to a minimum. As a turn-
key solution, the OPTIGA™ Trust X comes with OS, embedded application and complete
host side integration support. The extended temperature range of -40 to +105°C com-
bined with a standardized I²C interface and small USON-10 footprint will enable all your
embedded projects.
New: Open Source Host Code for OPTIGA™ Trust X
OPTIGA™ Trust X’s host code and documentation is now available as open source on
GitHub: https://github.com/Infineon/optiga-trust-x
Customers benefit from a direct communication line to developers and will immediately
and directly be informed of new versions, features and bug fixes. Be it the integration of
standard open-source crypto software libraries or the integration of the host code into
other systems – easily possible now.
