Naveen Kumar,
There is no dedicated example for A1006 authentification in Rapid-IoT studio, but Out Of Box project use this component to authenticate the device during BLE connection. Compile, download and extract Out Of Box project archive in your MCUXpressoworkspace. Then, import it from the file system.
You will find the a1006 authentification driver in Rapid IoT Kit Out Of Box Demo/RapidIot_Base/middleware/authentification/a100x.

API for mk64f authentification is located in Rapid IoT Kit Out Of Box Demo/auth.

Hope this helps,
Theophile
