1. A method for wireless communication at a first wireless device, comprising:
communicating, with a second wireless device, a first plurality of messages of a first message type that are acknowledged according to an acknowledgement procedure;
selecting, based at least in part on the first plurality of messages being acknowledged and according to a sampling configuration common to both the first wireless device and the second wireless device, a first subset of messages of the first plurality of messages and a first subset of bits from each message of the first subset of messages;
generating a key using bit values of the first subset of bits from each message of the first subset of messages;
encoding a message using the key; and
transmitting the encoded message to the second wireless device.
