摘要： The invention is directed to a signal-emission control device (100) for controlling emission of RF communication signals (Si) in a wireless communication network (140) that includes a transmitter device (152) and a receiver device (154). The emission is controllable with respect to a variable signal parameter (P). An emission-value ascertainment unit (102) is configured to ascertain variation-data indicative of an emission-value variation of signal-parameter values of the signal parameter. A scheduling unit (110) is configured to ascertain operation-trigger data indicative of operation conditions for triggering control of emission of the wireless RF communication signals in accordance with the ascertained emission-value. A transmitter-control unit (104) is configured to control operation of transmitter device for transmitting the communication signals (Si) according to the emission-value variation of the respective signal-parameter value upon fulfilment of the operation conditions. This enables an increase of the verisimilitude of the provided communication signals against illegitimate RF-based eavesdropping.

摘要： Methods, systems, and devices for wireless communications are described. Communication devices may perform secret key generation using a set of line-of-sight (LOS) communication modes to secure a physical channel. For example, a first device and a second device may communicate a set of reference signals over the physical channel using a set of LOS communication modes. The first device and the second device may generate a secret key based on the set of LOS communication modes, for example, by using information associated with the set of LOS communication modes to compute the secret key using a key derivation function that outputs the secret key. The first device and the second device may secure the physical channel by encrypting signaling between the first device and the second device with the secret key and communicating the signaling over the physical channel using LOS communications.

摘要： Systems, devices, and methods for communications among access points (APs) and mobile wireless devices are disclosed. A database having a persistent profile table (PPT) can be used to store information related to access point operations. Information related to a plurality of APs can be detected and stored in the PPT. Certain information may be common to multiple of the APs, allowing for compression of the data for more efficient storage. Fingerprint data related to the APs can be clustered based on a first order identifier (e.g., SSID, PLMN) and a second order identifier (e.g., MAC, MAC prefix, cell ID). The clusters can be further compressed by, for example, storing common features only once, and storing uncommon features individually, along with an identifier frame indicating which features are unique within the group of clusters. A mobile device can query the persistent profile table to verify the identity of unknown APs.

摘要： In one embodiment, an apparatus comprises an antenna to receive one or more radio signals, wherein the antenna is associated with a proximity-based access portal. The apparatus further comprises a processor to: detect, based on the one or more radio signals, an access request from a first device, wherein the access request comprises a request to access the proximity-based access portal using an access token associated with an authorized device; determine, based on the one or more radio signals, that the first device is within a particular proximity of the proximity-based access portal; obtain a first motion history associated with movement detected near the proximity-based access portal; obtain a second motion history associated with movement detected by the authorized device; and determine, based on the first motion history and the second motion history, whether the movement detected near the proximity-based access portal matches the movement detected by the authorized device.

摘要： A system of classifying devices and/or app instances a new or returning divides attributes generated from observations received from an uncharacterized device/software app into base-fingerprint attributes and predictor attributes, where the two kinds of attributes have different longevities. Predictor attribute tuples from attribute tuples having the same base fingerprint as the base fingerprint corresponding to the uncharacterized device/app, and the predictor attribute tuple corresponding to the uncharacterized device/app are analyzed using a machine learned predictor function to obtain a final fingerprint. Machine learning techniques such as logistic regression, support vector machine, and artificial neural network can provide a predictor function that can decrease the conflict rate of the final fingerprint and, hence, the utility thereof, without significantly affecting the accuracy of classification.

摘要： The disclosed embodiments relate to a system that camouflages EMI fingerprints in EMI emissions from a computing system to enhance system security. During operation, the system monitors the EMI emissions from the computer system during operation of the computer system to produce corresponding EMI signals. Next, the system determines a dynamic amplitude of the EMI emissions based on the EMI signals. If the dynamic amplitude of the EMI emissions drops below a threshold value, the system executes synthetic transactions, which have interarrival times that, when superimposed on a workload of the computer system, cause the computer system to produce randomized EMI emissions.

摘要： The disclosed embodiments relate to a system that camouflages electromagnetic interference (EMI) fingerprints in EMI emissions from a computing system to enhance system security. During operation, the system monitors the EMI emissions from the computer system while the computer system is operating to produce corresponding EMI signals. Next, the system performs a Fast Fourier Transform (FFT) operation on the EMI signals. The system then converts an output of the FFT operation into a frequency-domain representation of the EMI signals. Next, the system generates a camouflaging signal based on the frequency-domain representation of the EMI signals. Finally, the system outputs the camouflaging signal through a transmitter to camouflage EMI fingerprints in the EMI emissions from the computer system.

摘要： A system receives, from a user equipment, a request for access to a wireless communication network and identifies, based on the request, baseline radio frequency (RF) response information associated with the user equipment. The system obtains dynamic RF response information associated with the user equipment and authenticates, based on the dynamic RF response information and the baseline RF response information, the user equipment. The system thereby grants the user equipment access to the wireless communication network and determines context information associated with the user equipment. The system generates, based on the baseline RF response information and the context information, user equipment profile information and sends, to a base station associated with the wireless communication network, the user equipment profile information to facilitate access to the wireless communication network by the user equipment.
