Apparatus, methods, and computer-readable media for facilitating self-managed trust in Internet-of-Things networks are disclosed herein. An example method of trust management at a network manager includes enrolling a network endpoint with a network managed by the network manager. The example method also includes receiving trusted reference information for the network endpoint based on enrolling the network endpoint. Additionally, the example method includes performing verification of the network endpoint based on at least one of the trusted reference information or an attestation received from the network endpoint. Further, the example method includes enforcing policies to the network endpoint based on a result of the verification. Such trust management may improve privacy and security at the network, as well as reduce latency in responding to trust incidents.

Self-managed trust in internet of things networks

Methods, systems, and devices for communications are described. A device or a group of devices may generate data. The group of devices may receive a group profile from a node that identifies the devices to be included, and the group profile may include a function to be evaluated at each of the devices. The node may also provision evaluation parameters which may allow the device to provide authenticated aggregate data to a requesting third party, without sharing the data between the devices, thus concurrently maintaining individual data privacy and data provenance.

Secure multiparty computation for internet of things communications

Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more specifically to advertising discovery information, relaying discovery information, and to the secure relay of discovery information in wireless networks. Various frame structures are provided for such transmitting and relaying of discovery information. According to certain aspects of the present disclosure, security is provided for relaying discovery information. According to certain aspects of the present disclosure, compensation may be provided to a device that relays discovery information (e.g., when the relaying results in a transaction).

Peer-to-peer relaying of discovery information

Secure multiparty computation for Internet of Things communications

Methods, systems, and devices for wireless communications are described. Aspects include a device generating data to be sent to a receiving device and determining to provide provenance for the data. The device may generate a data identifier based on an identifier generation key and encrypt the data using an encryption key generated from a key associated with an owner of the device. The device may sign they encrypted data transmission using a signing key where the signing key is based on the encrypted data and the data identifier. In some cases, the device may send the data to a receiving device via one or more proxy devices. In some cases, multiple device may send signed data transmissions to a proxy device and the proxy device may process the multiple data transmission and send the processed data to the receiving device. The receiving device may verify provenance of the data.

Data provenance

Methods, systems, and devices for communications are described. A device or a group of devices may generate data. The group of devices may receive a group profile from a node that identifies the devices to be included, and the group profile may include a function to be evaluated at each of the devices. The node may also provision evaluation parameters which may allow the device to provide authenticated aggregate data to a requesting third party, without sharing the data between the devices and without sharing the data with the node, thus concurrently maintaining individual data privacy and data provenance.

Aggregate data provenance

Spatial spreading is performed in a multi-antenna system to randomize an 'effective' channel observed by a receiving entity for each transmitted data symbol block. For a MIMO system, at a transmitting entity, data is processed (e.g., encoded, interleaved, and modulated) to obtain Ndata symbol blocks to be transmitted in Ntransmission spans, where N&#x2265;1 and N&#x3e;1. The Nblocks are partitioned into Ndata symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices, where L&#x3e;1) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and transmitted via Ntransmit antennas in one transmission span. The Ndata symbol blocks are thus spatially processed with Nsteering matrices and observe an ensemble of channels.

Secure relay of discovery information in wireless networks

According to one aspect of the invention, a method is provided in which a control channel used for transmitting control information is partitioned into a plurality of subchannels each of which is operated at a specific data rate. For each of one or more user terminals, one of the subchannels is selected based on one or more selection criteria for transmitting control information from an access point to the respective user terminal. Control information is transmitted from the access point to a user terminal on a particular subchannel selected for the respective user terminal. At the user terminal, one or more subchannels are decoded to obtain control information designated for the user terminal.

Method and apparatus for providing an efficient control channel structure in a wireless communication system

A method, operational at a network device, for conveying congestion information across different strata of a multi-strata network is provided. An indication is obtained that a congestion level for at least one of a radio access network node and a core network node of a network has changed. Consequently, a one or more service parameters for a plurality of services, operating at a service stratum, are updated or adjusted on a per service basis based on the congestion level indication. The one or more service parameters are provided or sent to, at least one of, a node operating at a service stratum or a user device that obtains services over the network.

Dynamically adjusting network services stratum parameters based on access and/or connectivity stratum utilization and/or congestion information

Transmitter and receiver units for use in an OFDM communications system and configurable to support multiple types of services. The transmitter unit includes one or more encoders, a symbol mapping element, and a modulator. Each encoder receives and codes a respective channel data stream to generate a corresponding coded data stream. The symbol mapping element receives and maps data from the coded data streams to generate modulation symbol vectors, with each modulation symbol vector including a set of data values used to modulate a set of tones to generate an OFDM symbol. The modulator modulates the modulation symbol vectors to provide a modulated signal suitable for transmission. The data from each coded data stream is mapped to a respective set of one or more 'circuits'. Each circuit can be defined to include a number of tones from a number of OFDM symbols, a number of tones from a single OFDM symbol, all tones from one or more OFDM symbols, or some other combination of tones. The circuits can have equal size or different sizes. Different circuits can be used for full rate data (e.g., active speech) and low rate data (e.g., silence periods).

Multiplexing of real time services and non-real time services for OFDM systems

Methods, systems, and devices are described for direct device-to-device (D2D) communications in a subframe on a channel in an unlicensed radio frequency spectrum band. A user equipment (UE) may perform a listen-before-talk (LBT) procedure on the channel in the unlicensed radio frequency spectrum band. The UE may identify a time period between a completion of the LBT procedure and a boundary of a second subframe. The UE may transmit a Wi-Fi preamble and a variable length message on the channel during the identified timer period. The variable length message may include a duration that is time aligned with the boundary of the second subframe.
