1. A method comprising:
generating, at a physical (PHY) layer of a first device, an encoded and secured message comprising at least two parts, the generating including:
encoding, at the PHY layer of the first device, a message to produce an encoded message, and splitting, at the PHY layer of the first device, the encoded message into at least two encoded parts; or splitting, at the PHY layer of the first device, a message into at least two unencoded parts, and encoding, at the PHY layer of the first device, the at least two unencoded parts to produce at least two encoded parts; and
securing, at the PHY layer of the first device, the at least two encoded parts to produce the encoded and secured message comprising the at least two parts;
transmitting, by the first device, control information indicating a total number of secured and encoded parts of the encoded and secured message; and
after the transmitting the control information, transmitting, by the first device, the at least two parts of the encoded and secured message to a second device over at least two beam pair links (BPLs) associated with the first device and the second device, each of the at least two parts being transmitted over a single BPL.
