US11321474B2	Method and apparatus for multi-channel secure communication and data transfer A method, apparatus and computer program product are disclosed to provide for the selective establishment and use of secure communication channels to facilitate the exchange of data objects containing potentially sensitive information in a network environment. In some example implementations, upon detection that the processing of a network entity request implicates the exchange of non-public information amongst one or more other network entities, one or more secure communication channels are established between a secure transfer system and the relevant network entities such that non-public information neither passes to nor resides on system components associated with non-secure network entities.
US11321467B2	System and method for security analysis Methods, systems, and apparatus, including computer programs encoded on computer storage media, for security analysis are provided. One of the methods includes: determining a data risk value for data of an endpoint based on a number of classified files within the data and a type of classified files within the data; determining an endpoint risk value for the endpoint based on a user risk value and a cyber security risk value; determining a channel risk value for a set of channels through which the data is conveyable by the endpoint based on a number of channels within the set of channels and a type of channels within the set of channels; and rendering a map showing a security risk level of the endpoint, wherein the security risk level is based on the data risk value, the endpoint risk value, and the channel risk value.
US11321462B2	Device behavior anomaly detection A method of identifying anomalous behavior can include transforming input data to a series of numbers, determining first features and second features of the series of numbers that, given the same numbers in a different order, produce a different value for the respective feature, encoding the series of numbers by a key value indicating a number associated with a cell of a grid of cells to which the first and second features map, and determining, based on whether the key value has been previously provided, whether the input is anomalous.
US11321460B2	Information redistribution to reduce side channel leakage A logic circuit includes a data signal input, a computational module, a direct timing modulator and an amplitude and non-direct timing modulator. The data signal input inputs data signals. The computational module includes multiple logic elements interconnected to perform a logic function. The direct timing modulator modulates a propagation time of the input data signals from the data signal input to the computational unit, in accordance with a first set of control signals. The amplitude and non-direct timing modulator modulates the processing time of data signals by the computational module and the amplitude of data signals propagating through the computational module, in accordance with a second set of control signals.
