1. A first user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive, from a network node, an indication of first level shared information, that is shared between at least the first UE and a second UE, for deriving a physical layer security key from common sidelink information;
determine second level shared information, that is shared between the first UE and the second UE, for deriving the physical layer security key from the common sidelink information; and
communicate with the second UE using the physical layer security key derived from the common sidelink information based at least in part on the first level shared information and the second level shared information.
