Summary

Recommendation ITU-T X.1368 specifies: 1) basic models and procedures for securely updating firmware or software (FW/SW) of Internet of things (IoT) devices; and 2) requirements and capabilities for updating IoT FW.

A common secure update procedure is specified with general requirements. This procedure allows common IoT SW/FW updates to be securely implemented among stakeholders in the IoT environment, such as IoT device developers and IoT system/service providers.

This Recommendation focuses on updating FW, but it is applicable to updating any other SW of IoT devices.
