    Abstract: Disclosed is a method for secure transmission of small data of a machine type communication (MTC) device group, comprising a process wherein an MTC device and an MTC-Interworking Function (MTC-IWF) generate a shared key KIWF on the basis of a GBA procedure, the MTC device and a bootstrapping server (BSF) performing AKA authentication: a home subscriber server (HSS) determines whether the MTC device belongs to the MTC device group and whether said device has small data transmission and reception capabilities; if said device belongs to said group and has said capabilities, an AKA authentication vector generated on the basis of the MTC device group key is sent to said BSF; the BSF carries out AKA authentication with the MTC device on the basis of the received AKA authentication vector. Also disclosed is a system for secure transmission of small data of an MTC device group.

    Abstract: Methods, systems, and devices related to related to digital wireless communication, and more specifically, to techniques related to securing a user authentication procedure. In one exemplary aspect, a method for wireless communication includes transmitting an authentication message from a network node. The method also includes determining a failure value indicating a reason for failure of the authentication message. The method also includes encrypting the failure value and an identifier. The method also includes transmitting an encrypted response message to the network node. In another exemplary aspect, a method for wireless communication includes transmitting an authentication message to a terminal. The method also includes receiving an encrypted response message from the terminal. The method also includes decrypting the encrypted response message to determine the failure value and the indicator.

    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.

    Abstract: Provided is a SIP-based method for secure communication between MTC devices, including that an SIP server establishes a secure connection with a source MTC device and a secure connection with a target MTC device respectively through a GBA manner or a GBA-push manner, the SIP server generates an application layer session key, sends the application layer session key to the source MTC device through the secure connection between the SIP server and the source MTC device, and sends the application layer session key to the target MTC through the secure connection between the SIP server and the target MTC device. A SIP-based system and apparatus for secure communication between MTC devices are also provided. The establishment of a secure connection between MTC devices based on an SIP protocol can be implemented.
