Hi Shuyang,

Image encryption is not supported for the moment on CC2340R5. We are currently working on enabling this feature.

In the meantime, I'd recommend to ensure firmware updates are done over encrypted connection - see https://software-dl.ti.com/simplelink/esd/simplelink_lowpower_f3_sdk/8.10.00.55/exports/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/ble5-oad-index-mcuboot-cc23xx.html for additional details.

Best regards,
