IoT SAFE

What is IoT SAFE (IoT SIM Applet For Secure End-to-End Communication)?

IoT SAFE is an interoperable GSMA standard that turns the SIM into a miniature crypto-safe inside a device. It uses this secure element to establish a Datagram Transport Layer Security (DTLS) session with a trusted application cloud or server.

The standard provides a common application programming interface (API) for using the SIM as a root of trust. IoT devices can then authenticate themselves and exchange data only with approved systems. This ensures that all data sent or received is encrypted and protected from unauthorized access.

By relying on the SIM’s secure hardware, IoT SAFE enables device makers and service providers to add strong security without needing extra chips or complex integrations. It works across different networks and device types, making it a scalable choice for secure IoT deployments.

IoT SAFE strengthens IoT security by using the SIM card itself as the foundation for trusted, encrypted, end-to-end communication.
