SIMbaeTM Credentials Exchange Manager

Securely Update IoT Application Security Credentials Over the Mobile Network

SIMbaeTM Credentials Exchange Manager (S-CEM)* ensures secure end-to-end encrypted updates.

*formerly SIMbae Key Exchange Manager (S-KEM)

The name was changed as the term “Key” was meant to indicate an application key, password, or other credential. The term Key caused confusion as it led some to assume it was related to the SIM authentication key or Ki, which we do not touch.

SIMbae’s Credentials Exchange Manager enables the remote updating of the IoT application’s security credentials in a standards-based method that leverages the existing components of a connected device and service. Running on the device’s SIM, SIMbae uses encrypted mobile messages to securely deliver an updated password or other credential to the device’s IoT application.
