US10257791B2 Method and apparatus for power and user distribution to sub-bands in NOMA systems
Power allocation in NOMA systems for example on the basis Proportional Fairness calculations depends on knowledge of user throughput on a specified sub-band, which implies that users have already been allocated to particular sub-bands. Meanwhile, maximum throughput can generally be achieved where there is the greatest possible difference in transmission power for the users on a given sub-band, so that optimal allocation of users to sub-bands requires knowledge of the power available for each user. A mechanism is proposed based on iteratively applying a waterfilling algorithm to distribute power across a progressive subset of sub-bands to provisionally distribute the power budget across that subset of sub-bands, where at each iteration the water filling algorithm is carried out for each possible combination of users assignable to the newly considered sub-band using a floor for that sub band proportional to the reciprocal of the square of the highest channel gain value of any user in that combination, and calculating a throughput for that combination with the corresponding power attribution, whereby the combination retained for the next iteration (with an additional sub-band) is whichever gives the highest throughput. This process is thus repeated until users are assigned to all sub-bands, whereupon power allocations from the last iteration are definitive.

Upon successful application of the sequence of proof rules, the encrypted version of the sensitive content is prepared for publication and optionally published in encrypted form. At the future time, an encryption key is received for the encrypted version of the sensitive content and the encrypted version of the sensitive content is decrypted with the encryption key to produce the sensitive content.
US10255436B2 Creating rules describing malicious files based on file properties
Systems and methods automatically determine rules for detecting malware. A fingerprint representing a file is received. A set of nearest neighbor fingerprints from at least a set of malware fingerprints that are nearest neighbors are determined. The set of malware fingerprints are analyzed to determine a representative fingerprint. A malicious file detection rule is generated based, at least in part, on the representative fingerprint.
US10255434B2 Detecting software attacks on processes in computing devices
Various embodiments include methods for detecting software attacks on a process executing on a computing device. Various embodiment methods may include monitoring structural attributes of a plurality of virtual memory regions utilized by the process, and comparing the monitored structural attributes to the expected structural attributes of the plurality of VMRs. Various embodiment methods may further include determining whether the monitored structural attributes represent anomalous behavior of the process based on the comparison between the monitored structural attributes and the expected structural attributes.
US10255429B2 Setting an authorization level at enrollment
Systems, methods, and other embodiments associated with setting an authorization level at enrollment. According to one embodiment, a method includes a accessing an interface on a device. Initiation information for a user of the device is provided to an authorizer. The authorizer is associated with a class. Verification data is received from the authorizer. An enrollment token is then generated based on the verification data. The enrollment token includes an authorization level that defines security parameters for the device.
US10255426B2 Keyboard device and data communication method using the same
A keyboard device and a data communication method using the keyboard device. The data communication method includes generating, by the keyboard device, data that is a set of commands to be executed by a computer using a key input signal that is generated when a key is input, transmitting, by the keyboard device, the generated data to the computer, thus allowing the computer to execute each command corresponding to the data, and receiving, by the keyboard device, results of executing the command corresponding to the data from the computer, wherein the command includes a line coding method to be used when the computer transmits data to the keyboard device, and wherein the computer generates a toggle key signal to correspond to the line coding method and transmits the toggle key signal to the keyboard device.
US10255422B1 Identity proxy for access control systems
A hardware security token in contact with a user's body can send a signal via interbody communication to one or more electronic devices associated with a system of electronic devices having unified access controls such that a user can access each of the electronic devices using the same credentials. The signal sent by the hardware security token can be deputized by a user in possession of credentials to the system as a temporary proxy for that user's identity. In other examples, the signal sent by the portable security token can be deputized by a user in possession of credentials to the system as a temporary proxy for another user's identity. In some embodiments, the proxy can expire after a period of time or after a particular event occurs.
