USE CASES / SIM-ROOTED IDENTITY & AUTHENTICATION

Every cellular device already ships with a secure element. Use it.

SIM-rooted identity and cryptography — GSMA IoT SAFE-based credential storage, signing, and TLS from the SIM, with no extra hardware.

// The problem

IoT identity is usually the weakest link in the chain.

Credentials baked into firmware get extracted and cloned. Software keystores are only as strong as the OS around them. Dedicated secure elements add cost and board space that constrained devices don't have. The result: device identity that can't be trusted, TLS backed by keys sitting in flash, and security reviews that stall procurement.

// Why SIM-native

The SIM is a certified secure element that ships in every cellular device.

The SIM already performs cryptographic network authentication for a living, inside tamper-resistant hardware with a formal security certification lineage. GSMA's IoT SAFE standard defines how applications can use that same environment as a root of trust: keys generated and stored on the SIM, cryptographic operations performed on-card, secrets never exposed to the device OS.

// THE OUTCOME

Hardware-grade device identity and channel security across the whole fleet, at SIM cost rather than secure-element cost — manageable remotely for the device's entire life.
