Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a key derivation function and a set of physical layer parameters, a secret key for encrypting a unicast physical channel at a physical layer, wherein the secret key is a UE-specific secret key. The UE may transmit, to a base station, an encrypted transmission over the unicast physical channel based at least in part on the secret key. Numerous other aspects are described.

An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- determine, based at least in part on a key derivation function and a set of physical layer parameters, a secret key for encrypting a unicast physical channel at a physical layer, wherein the secret key is a UE-specific secret key;
- and
- transmit, to a base station, an encrypted transmission over the unicast physical channel based at least in part on the secret key.
An apparatus for wireless communication at a base station, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- determine, based at least in part on a key derivation function and a set of physical layer parameters, a secret key for encrypting a unicast physical channel at a physical layer, wherein the secret key is a UE-specific secret key;
- and
- transmit, to a user equipment (UE), an encrypted transmission over the unicast physical channel based at least in part on the secret key.
A method of wireless communication performed by a user equipment (UE), comprising:
- determining, based at least in part on a key derivation function and a set of physical layer parameters, a secret key for encrypting a unicast physical channel at a physical layer, wherein the secret key is a UE-specific secret key;
- and
- transmitting, to a base station, an encrypted transmission over the unicast physical channel based at least in part on the secret key.
