Scrambling for wireless communications

Abstract:

Aspects of the present disclosure describe scrambling of information for wireless communications to prevent deciphering or altering by unintended recipients. An example method may include generating, by a first device, a scrambling key based on at least one of a freshness parameter or a private key. The private key is known by the first device and a second device. The method also includes scrambling a payload based on the scrambling key at a physical layer. A packet includes the payload for wireless transmission from the first device to the second device via a shared channel.
