Abstract: The present disclosure describes methods, systems and devices for establishing secure communication between a user equipment and a service application in a wireless communication. One method includes receiving, by the user equipment, an authentication and key management for service applications identifier (AKMAID) from an authentication server function (AUSF) upon successful completion of an authentication process for registering the user equipment with the communication network. The method also includes storing, by the user equipment, the AKMAID; deriving, by the user equipment, an application key based on a base authentication key; sending, by the user equipment, a communication request to the service application, the communication request comprising the AKMAID; and receiving, by the user equipment, an application session establishment response to the communication request from the service application to establish a security communication session between the user equipment and the service application based on the application key.
