The new OPTIGA™ Trust M solution from Infineon Technologies helps manufacturers of IoT devices connected to cloud-computing services to enhance the security of their products while at the same time improving system performance.

The OPTIGA Trust M SLS32AIA series, a single-chip security controller solution, stores unique device credentials, and enables devices to connect to the cloud up to ten times faster than software-only alternatives.

When embedded in an IoT end-point device, an SLS32AIA chip can enable security functions such as:

  • Mutual authentication
  • Secure communication
  • Data store protection
  • Lifecycle management
  • Power management
  • Secure updates
  • Platform integrity protection


OPTIGA Trust family: End-to-end security from device to cloud

The OPTIGA Trust M solution also eases the provisioning of cloud services in IoT end-points. When deploying an OPTIGA Trust M solution in an embedded device, critical assets such as certificates and key pairs used to identify a device can be programmed into the chip at a secure Infineon factory.

Infineon minimizes design and deployment effort by providing a cryptographic toolbox, a protected I2C interface, and open-source code hosted on GitHub. In addition, the SLS32AIA high-end security controller is certified according to CC EAL6+, offering a high level of security, and provides advanced asymmetric cryptography functions, including 256-bit and 384-bit ECC and 1024-bit and 2048- bit RSA. It also supports secure software updates in the field.

There are two variants of the OPTIGA Trust M solution, both supplied in a 3mm x 3mm USON package:

  • SLS32AIA010MS covering a standard temperature range of -25°C to 85°C for most commercial implementations
  • SLS32AIA010MH offering an extended temperature range of -40°C to 105°C for harsh industrial environments


A Member of the OPTIGA Trust Family

Infineon’s OPTIGA™ Trust M is the latest addition to the OPTIGA Trust family of embedded security solutions, which provide an anchor of trust for IoT devices connected to the cloud.

The need for strong device authentication has never been higher. Software alone is not enough to protect embedded systems as it can be copied, reverse-engineered and exploited with ease. Secured hardware is needed to store sensitive data, provide encryption functionality, and detect manipulation.

Embedded system designers can rely on Infineon’s OPTIGA™ family of security solutions to protect the confidentiality, integrity and authenticity of information and devices.

  • True random number generator
  • Hibernate mode for zero power consumption
  • Up to 10kbytes of user memory
  • Device security monitor
  • Lifetime of up to 20 years
  • Industrial automation
  • Building automation
  • Smart home devices
  • Consumer devices
  • Drones



New Shield Board for OPTIGA Trust M Enables Fast Development of Secure IoT Systems

Infineon’s Shield2Go board for the OPTIGA™ Trust M security chip supports fast evaluation and development of IoT end-point devices which require secure cloud connections. It features one OPTIGA Trust M security chip on an easy-to-handle PCB.

Design engineers can build systems by combining multiple Shield2Go boards with the Infineon My IoT adapter board. The adapter board is compatible with the Arduino form factor, and enables fast development in a familiar project environment.

Infineon also supports the Shield2Go board with open-source host code for the OPTIGA™ Trust M, supplied via GitHub. This provides information directly about new versions, features and bug fixes, and enables easy integration of standard open-source cryptographic software libraries or of the host code into other systems. The host code is licensed under the MIT License.
