  • Patent number: 11838308
    Abstract: The present disclosure relates to a computer-implemented method and an apparatus for classifying anomalies of one or more feature-associated anomalies in network data traffic between devices in a first part of a network and devices in a second part of the network. The method comprises retrieving at least one network data traffic sample and determining one or more feature-associated anomaly scores for the retrieved at least one network data traffic sample. The method further comprises determining feature importance of each feature of a feature-associated anomaly score and classifying one or more anomalies based on the determined one or more feature-associated anomaly scores and the determined feature importance.
    Type: Grant

  • Publication number: 20220408243
    Abstract: A user equipment (“UE”) in a wireless communication network can generate a padded identifier by inserting a padding bitstring in a field of an identifier associated with the UE. The UE can further encrypt the padded identifier to generate a concealed padded identifier. The UE can further transmit the concealed padded identifier to a network node operating in the wireless communication network.

  • Patent number: 11444964
    Abstract: The present disclosure relates to a method and an apparatus for training a model for detecting anomalies in network data traffic between devices in a first part of a network and devices in a second part of the network. The method comprises collecting feature samples of network data traffic at a monitoring point between a first and a second part of the network, and training the model for detecting anomalies on the collected feature samples using a plurality of anomaly detection, AD, trees. The training comprises creating the plurality of AD trees using respective subsets of the collected feature samples, at least some of the AD tree comprising subspace selection nodes and anomaly-catching nodes to a predetermined AD tree depth limit.
