  • The STSAFE-A1SX is a secure element that provides security services for the implementation of Sigfox LPWAN (low-power wide area network) security in Sigfox IoT devices.

    Connected to the applicative microcontroller (MCU) of a Sigfox IoT device, the STSAFE-A1SX assists the MCU of this IoT device to achieve recognition, authentication and connection to the Sigfox network. The IoT device is then able to ensure and verify the integrity of exchanged data. Optionally, it can also ensure the confidentiality of exchanged data.
    It comes preloaded with the Sigfox IDs and keys, and does not require any additional configuration.
    The STSAFE-A1SX drastically simplifies and secures device onboarding. The customer no longer needs to save credentials to the IoT storage at manufacturing time. ST takes care of loading credentials into the secure element in a secure way. The IoT device can then directly exploit the Sigfox credentials preloaded in the secure element.
    The STSAFE-A1SX is a full turnkey solution running a proprietary application and operating system on top of the latest secure microcontroller generation.
