Abstract: Described are methods and devices for communication between local networks and global networks. In some examples, a method comprises storing mapping data for multiple hosts in a global network and in a local network. The method further comprises receiving a first data packet from one of the multiple hosts in the local network. The first data packet comprises a first source address being the local network address of the host in the local network, a first destination address being the local network address of the host in the global network and payload data. The method further comprises determining, based on the mapping data, the global network address of the host in the local network and a global network address of the host in the global network, and sending a second data packet over the global network.

Abstract: This disclosure relates to classifying websites. A processor calculates importance values between a test website and multiple neighbour websites that are connected by way of one or more hyperlinks between that neighbour website and the test website. The processor then selects one or more of the multiple neighbour websites, based on the importance value. For each website in the selected one or more of the multiple neighbour websites and the test website, the processor determines content features for the website, and evaluates a trained machine learning model for the website, based on the content features to calculate multiple output values for the website. The processor then aggregates corresponding output values for each of the test website and the selected one or more of the multiple neighbour websites to calculate a classification value that classifies the test website.

Abstract: A portable device for use in establishing trust including a communications module for communicating with a host machine; embedded trusted data; a virtual machine module for instantiating a virtual machine on the host machine; and a security module for including a secure application in the virtual machine to perform an attestation process using the embedded trust data to authenticate the host machine.
