摘要： According to at least one aspect of the present disclosure, a method for determining whether two flows are related is provided. The method comprises identify a first flow; identify a second flow; collect one or more attributes of one or more packets of the first flow and second flow during an interval of time; determine a flow similarity of the first flow and the second flow based on the one or more attributes; determine that the flow similarity exceeds a similarity threshold; and responsive to determining that the flow similarity exceeds a similarity threshold, determine that the first flow and second flow are related flows.

摘要： According to at least one aspect of the present disclosure a method for detecting tunneled or multiplexed flows is provided. The method comprises: receiving an input; responsive to receiving the input, extracting a set of attributes of the input flow; responsive to extracting the set of attributes, reducing the dimensionality of the set of attributes to produce a reduced attribute set; responsive to producing the reduced attribute set, producing an output based on the reduced attribute set and a model; responsive to producing the output, comparing the output to the input to determine an error or loss; and responsive to determining the error or loss, categorizing the input as a multiplexed flow based on a threshold error or loss value.

摘要： According to at least one aspect of the present disclosure, a method for grouping constituent flows of a multiplexed or tunneled flow is provided. The method comprises receiving one or more packets of the multiplexed flow; responsive to receiving the one or more packets, determining one or more attributes of the one or more packets of the multiplexed flow; determining, based on the one or more attributes, a predicted state of a next packet of the multiplexed flow; receiving the next packet; responsive to receiving the next packet, determining whether the next packet has an observed state that is similar to the predicted state; and responsive to determining that the observed state is similar to the predicted state, grouping the packet with the constituent flow.

摘要： Techniques for geospatial-temporal pathogen tracing in zero knowledge include: generating, by a first user device, a first proximity token for contact tracing; receiving, by the first user device, a second proximity token from a second user device; generating, by the first user device, a hash based on the first proximity token and the second proximity token; generating, by the first user device using a prover function of a preprocessing zero knowledge succinct non-interactive argument of knowledge (pp-zk-SNARK), a cryptographic proof attesting that an individual associated with the first user device tested positive for a pathogen; transmitting, by the first user device, first publicly verifiable exposure data including at least the cryptographic proof and the hash to a public registry; and applying at least the first publicly verifiable exposure data and second publicly verifiable exposure data to a machine learning model, to obtain actionable intelligence associated with the pathogen.

摘要： A method of sending a flow of a plurality of data packets across a data network from a source node to a destination node is provided, the data network including a plurality of links between nodes. The method includes: (a) determining a set of weights, the weights corresponding to respective links of the plurality of links, such that obeying the set of weights during data transmission tends to minimize side channel leakage for the flow; and (b) routing packets of the flow along the plurality of links of the data network according to their respective weights. A corresponding apparatus, system, and computer program product are also provided.

摘要： Techniques for geospatial-temporal pathogen tracing include: obtaining, from multiple mobile devices in association with a first time, first contact tracing data including at least first geospatial traffic data and first values of a set of attributes associated with a pathogen; obtaining, from the multiple mobile devices in association with a second time, second contact tracing data including at least second geospatial traffic data and second values of the set of attributes associated with the pathogen; and applying at least the first contact tracing data and the second contact tracing data to a machine learning model, to obtain actionable intelligence associated with the pathogen.
