1. A user equipment (“UE”) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
perform primary authentication with a mobile communication network;
receive a security mode command (“SMC”) message comprising slice-specific security requirement information (“SSI”) and a slice security requirement identifier (“SRID”), wherein the SSI includes a security requirement type parameter indicating whether to derive a dedicated security context after the primary authentication, and wherein the SRID identifies a security requirement information corresponding to a single network slice selection assistance information (“S-NSSAI”); and
apply slice security for control plane and user plane traffic related to a network slice in response to the security requirement type parameter included in the SSI indicating to derive the dedicated security context after the primary authentication,
wherein to apply slice security for control plane and user plane traffic related to the network slice, the at least one processor is configured to cause the UE to derive at least one slice-specific security key based on the received SSI and the SRID.
