    Abstract: A node in a distributed network computes a hash of content for a service received in a data packet. The node verifies the data packet by comparing the hash of the content of a service received from a neighboring node to a hash of the content computed by the node. An amount of content of the service having a same identification is accumulated in a trusted execution environment (TEE) of the node, and a signature based on code stored in a TEE of the node is generated. The node then sends the data packet to the next neighboring node, where the service-related information includes the service ID, a hash of the service content and the signature. The service records with the accumulated amount of service content, accumulated hash values, and nodes' signatures are sent to the validation nodes to reach consensus for the service provided.

    Abstract: A data management system for collecting data of users from sensors at an event. An event-specific token corresponding to the event attended by the users is generated, where the event-specific token includes event-specific signatures about the users attending the event, and the signature of the event venue or facility. The public data is sent to public storage as an aggregation of the collected data and tagged with the event-specific token. The public data is statistically analyzed to track interactions and assess risks of the user's potential infection of a communicable disease based on anomalous activity detected at the event, or based on the notifications from the event attendees, which are matched and validated anonymously using the event-specific tokens. Based on a result of the statistical analysis, an advisory alert is sent to the users to warn them of a level of risk of harm based on attendance of the event.

    Abstract: The present invention provides a network communication method and device. The method includes: receiving, by a VNC on a physical host, a network communication packet sent by a first virtual machine of which a host machine is the physical host and which has a mapping relationship with the VNC, where a source address carried in the network communication packet is an address of the first virtual machine, a destination address carried in the network communication packet is an address of a second virtual machine or an address of another physical host; selecting, by the physical host, a VPN network corresponding to the VNC on the physical host according to preset correspondence between the VPN network and the VNC; and sending, by the physical host, the network communication packet through the selected VPN network. The present invention lowers the restriction on setting an IP address of a virtual machine in a VPN.

    Abstract translation: 本发明提供一种网络通信方法和装置。 该方法包括：由物理主机上的VNC接收由主机是物理主机的第一虚拟机发送并与VNC具有映射关系的网络通信分组，其中在 网络通信分组是第一虚拟机的地址，网络通信分组中承载的目的地地址是第二虚拟机的地址或其他物理主机的地址; 物理主机根据VPN网络和VNC之间的预设对应关系，选择物理主机上对应VNC的VPN网络; 并由物理主机通过所选择的VPN网络发送网络通信包。 本发明降低了在VPN中设置虚拟机的IP地址的限制。
