Storing a key-string value securely

Question

I need to keep safe a key-string value (generated inside my app) on the device in a secure manner so that it cannot be accessed by unauthorized users or any other universal apps. This key value is used for making a reference to a table (inside OS) and I need to protect this key completely.
