Methods and apparatus for securing communications

A method the method comprising:

• receiving, by a second device, control information indicating a total number of secured and encoded parts of an encoded and secured message;
• after the receiving the control information, receiving, by the second device, at least two parts of the encoded and secured message from a first device over at least two beam pair links (BPLs), each of the at least two parts being received over a single BPL;
• and
• generating, at a physical (PHY) layer of the second device, a received message from the at least two parts of the encoded and secured message, the generating including:
• unsecuring, at the PHY layer of the second device, the at least two parts of the encoded and secured message to produce at least two encoded parts;
• and
• combining, at the PHY layer of the second device, the at least two encoded parts, and decoding, at the PHY layer of the second device, the combined at least two encoded parts to produce the received message;
• or decoding, at the PHY layer of the second device, the at least two encoded parts to produce at least two unencoded parts, and combining, at the PHY layer of the second device, the at least two unencoded parts to produce the received message.

A method comprising:

• generating, at a physical (PHY) layer of a device, a second message, the generating the second message including:
• encoding, at the PHY layer of the device, a first message to produce an encoded message, and splitting, at the PHY layer of the device, the encoded message into at least two encoded parts;
• or
• splitting, at the PHY layer of the device, a first message into at least two unencoded parts, and encoding, at the PHY layer of the device, the at least two unencoded parts to produce at least two encoded parts;
• generating, by the device, control information comprising a first indicator indicating a total number of secured and encoded parts of the second message, a second indicator indicating an ordering index of a first secured and encoded part of the at least two encoded parts scheduled by the control information, and a third indicator indicating a beam pair link (BPL) index used to communicate the first secured and encoded part scheduled by the control information;
• transmitting, by the device, the control information;
• and
• after the transmitting the control information, transmitting the second message including the secured and encoded parts to a second device over at least two beam pair links (BPLs) associated with the device and the second device, each of the at least two encoded parts being transmitted over a single BPL.

A first device comprising:

• one or more processors;
• and
• a non-transitory memory storage comprising instructions that, when executed by the one or more processors, cause the first device to perform operations including:
• generating, at a physical (PHY) layer of the 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 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 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.
