Complete cloud security solution protects IoT devices from cyber-attack

The OPTIGA™ Trust M tamper-resistant security solution from Infineon is Common Criteria EAL6+ certified. The secure element can be used with any MCU or application processor to enhance the security of IoT designs.

The OPTIGA Trust M from Infineon is a high-end security solution which provides an anchor of trust for connecting IoT devices to the cloud, giving every IoT device its own unique identity. This individual, turnkey solution offers secure, zero-touch onboarding and the high performance needed for quick cloud access.

The OPTIGA Trust M chips and supporting software offer a wide range of security features. In particular, they support common asymmetric cryptography algorithms including:

RSA® up to 2048
AES key up to 256, HMAC up to SHA512
TLS v1.2 PRF and HKDF up to SHA512

The turnkey set-up with full system integration minimizes the design, integration and deployment effort required of product manufacturers. The OPTIGA Trust M development process is certified according to the security standard IEC 62443-4-1 for industrial automation and control systems, acting as an enabler to achieve component-level certification according to IEC 62443-4-2.

The OPTIGA Trust M security solution is specified in two operating-temperature ranges:

SLS32AIA010MK at a standard temperature range of -25°C to 85°C for most commercial implementations
SLS32AIA010ML at an extended temperature range of -40°C to 105°C for harsh industrial environments

The OPTIGA Trust M chip is supplied in a USON-10 package that has a footprint of 3 mm x 3 mm.

Development Kit

Part Number: TRUSTMIOTSDKTOBO1

The OPTIGA™ Trust M IoT Security Development Kit is the easiest way to develop and evaluate end-to-end security use cases for IoT devices. The kit enables customers to build prototypes of security applications and build full-featured IoT applications. The board includes:

OPTIGA Trust M security solution
PSoC™ 62, based on an Arm® Cortex®-M4/Cortex-M0+-based microcontroller
AIROC™ CYW43012, a combination system-on-chip which supports dual-band 2.4 GHz and 5.0 GHz Wi-Fi® 4/Bluetooth® 5.0 networking

This development board is supplied with two ready-to-use security use cases:

Secured communication with AWS over MQTT using cryptography support from the OPTIGA Trust M
Secure, zero-touch cloud provisioning using a CIRRENT™ Cloud ID and the pre-provisioned X.509 certificate delivered with the OPTIGA Trust M

The kit is supported by the ModusToolbox™ design tool. The OPTIGA Trust M host library is available as open source code.
