摘要： A interference detection device (22) perform the following actions: receiving individual position data from mobile terminals (4(j)) which individual position data indicates an area (12(j)) in which individual ones of the mobile terminals (4(j)) are located based on positioning signals received by the mobile terminals (4(j)); identifying if individual position data may have been affected by one or more interfering signals transmitted by interfering device (14(m)) and interfering with the positioning signals; (A) identifying if a number of mobile terminals (4v(j)) in a first area (18) is higher than a maximum threshold number, and, if so, determining that individual position data of the number of mobile terminals (4v(j)) may have been affected by the interfering signals; or (B) identifying if a number of the mobile terminals (4(j)) in a second area (36) is lower than a minimum threshold number; and, if so, determining that individual position data of the number of mobile terminals (4(j)) may have been affected by interfering signals; or (C) receiving further individual position data which indicates further areas (18) in which mobile terminals (4(j)) are located based on another positioning technique than a positioning technique used to determine the individual position data as received from the mobile terminals (4(j)); determining if the areas (12(j)) overlap with the further areas (18) at least to a minimum extent, and, if not, determining that individual position data of the mobile terminals (4(j)) may have been affected by the interfering signals.

摘要： Some embodiments of the time resilient system and methods disclosed herein can be configured to detect and defend against invalid time signals. According to various embodiments of the disclosed technology, the time resilient system include a receiver for collecting time signals sourced from an external clock. By way of example only, the external clock may be a high precision clock housed within a Global Positioning System. Other embodiments may include an internal clock calibrated to a time reflected on the external clock so that the internal clock and the external clock are synchronized. Additionally, a controller may monitor changes in time signals of the external over a period of time against the internal clock, where the system is alerted of a timing attack when the time signals collected from the receiver deviate a pre-determined time range with the time of the internal clock.

摘要： A null steering adjuster in a stationary wireless network identifies the presence or absence of a current set of phase differences in a dataset. The dataset includes legitimate sets of phase differences detected between radio frequency signals received by multiple antennas from respective legitimate sources. The current set of phase differences is detected between radio frequency signals currently received by the antennas. When the current set of phase differences is absent from the dataset, a null is created in the antenna pattern of the antennas in the direction of the currently-received radio frequency signals. When the current set of phase differences is present in the dataset, the antenna pattern is maintained.

摘要： A communication apparatus includes a reference signal generating section, a transmitting section, a propagation estimating section, a first data acquiring section, and a decoding section. The reference signal generating section generates a first reference signal to enable a communicating party to estimate a propagation environment. The transmitting section transmits the first reference signal. The propagation estimating section estimates a first propagation estimation value of the propagation environment using a second reference signal transmitted from the communicating party. The first data acquiring section generates first data using the first propagation estimation value. The decoding section decodes a transmission signal encoded using a second propagation estimation value that is estimated by the communicating party using the first reference signal, to obtain second data using the first data.

摘要： A device and method providing audio-based, continuous authentication of a user to provide access to a processing device. A user echoprint model is created while a user interacts with an authentication interface for another authentication method of the device, transparently to the user. The sound waves are user-specific and inaudible. The user-specific sounds are reflected by the user and used to construct an echoprint which can be compared by a previously constructed user-specific, echoprint model. If the result is positive, access to the processing device may be allowed. Access to the processing device is based on the audio authentication or the alternative authentication is based on the result of audio authentication and updates a device state indicating whether the display is on or off and whether the device is locked or unlocked.
