Hardware authentication for IoT
SORACOM Endorse offers hardware-based device authentication for any device with a SORACOM Air SIM.
Air SIMs can send an authentication token to Endorse. This token is signed using a private SORACOM key and allows strong authentication based on SIM/device combination (IMSI + IMEI), preventing misuse of stolen SIMs.
Because authentication is specific to a device and SIM, Endorse is portable across communication networks, including cellular, Wi-Fi, LoRa, or Sigfox.
Why SIM authentication?
- Highly tamper resistant, extremely difficult to falsify or
duplicate. - Data communication enabled only when a SIM’s unique
IMSI is registered with a mobile network provider. - Security keys are exchanged based on private information
unique to each SIM, enabling user authentication and
encryption of all data communications. - Can be locked to a specific device via console or API

Capabilities
- Provision identity-based login for connected devices
- Authenticate devices across networks
- Connect confidently to private servers, even when sending
traffic over the Internet
