    摘要: A device within a small cell may establish a first secure communication channel between the device and a network device based on a first type of encryption. The device within the small cell may transmit data between the small cell and a core network via the first secure communication channel. The device within the small cell may receive information associated with a second type of encryption, wherein the second type of encryption is different from the first type of encryption. The device within the small cell may terminate the first secure communication channel. The device within the small cell may establish a second secure communication channel between the device and the network device based on the information associated with the second type of encryption. The device within the small cell may transmit further data between the small cell and the core network via the second secure communication channel.

    摘要: In an approach to facilitating data transmission utilizing peer-to-peer communications and wireless ad hoc networks, one or more computer processors detect one or more data transmission failures. The one or more computer processors rank the one or more detected data transmission failures. The one or more computer processors detect one or more subsequent devices. The one or more computer processors determine one or more statuses associated with the detected one or more subsequent devices. The one or more computer processors the one or more detected subsequent devices based on the determined the determined statuses. The one or more computer processors match the one or more ranked data transmission failures with the one or more ranked subsequent devices. The one or more computer processors transmit the one or more data transmission failures with one or more matched subsequent devices.

    摘要: Systems, methods, and computer-readable media are disclosed for systems and methods for autonomous device authentication and compartment unlocking. Example methods may include determining, by a user device, an identifier associated with a target Bluetooth Low Energy peripheral device, receiving a beacon from a Bluetooth Low Energy peripheral device, and determining, using the beacon, that the Bluetooth Low Energy peripheral device is the target Bluetooth Low Energy peripheral device. Example methods may include establishing a connection with the target Bluetooth Low Energy peripheral device, and sending a signal to the target Bluetooth Low Energy peripheral device to implement an action, where the signal comprises a resource identifier, and where the target Bluetooth Low Energy peripheral device controls access to a plurality of resources, and uses the resource identifier to identify a resource of the plurality of resources at which to implement the action.

    摘要: 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.

    摘要: A network node selectively encrypts messages between a user plane node and a control plane node in a network system. The user plane node and the control plane node negotiate a connection and indicate an encryption level for the connection. The encryption level is selected from an Information Element (IE) level, a message level, or a feature level. The user plane node and the control plane node selectively encrypt at least a portion of the messages between the user plane node and the control plane node based on the encryption level for the connection.

    摘要: A communication method and a communications apparatus are provided. The method includes: when receiving a first PDU session establishment request sent by a UE, encrypting, by an access and management network element (AMF), user information in the request, to obtain encrypted user information; and sending, by the AMF, a second PDU session establishment request to an SMF in response to the first PDU session establishment request, where the second PDU session establishment request carries the encrypted user information. In this manner, after the UE accesses a core network, an AMF entity may encrypt user information of the UE. The interaction information between NF entities, for example, the AMF entity and an SMF entity, carries the encrypted user information, which helps prevent user privacy leakage.
