Downlink message protection for ambient wireless devices

An ambient wireless controller, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the ambient wireless controller to:
• receive a message from an application function associated with a network entity;
• determine one or more protection applications to apply to the message;
• apply the one or more protection applications to the message to obtain an encoded downlink message;
• and
• transmit, for one or more ambient wireless devices, the encoded downlink message, wherein the message comprises the encoded downlink message, a downlink information for the encoded downlink message, a first key, a token, or any combination thereof.

A method for wireless communications at an ambient wireless device, comprising:

• receiving a downlink message comprising a first configuration for the ambient wireless device associated with one or more services, wherein the one or more services are associated with location or tracking;
• enabling the one or more services at the ambient wireless device based at least in part on the first configuration;
• receiving an encoded downlink message comprising a first key;
• decoding the encoded downlink message based at least in part on a second key, the encoded downlink message comprising a second configuration;
• and
• modifying the one or more services or activating a response transmission associated with the ambient wireless device based at least in part on the second configuration.
