Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable storage medium for tracing an attack source in a service function chain overlay network. In example embodiments, a request for tracing an attack source of an attacking data is sent at the attack tracer to a first service function chain domain of a plurality of service function chain domains through which the attacking data flow passes subsequently. The request includes flow characteristics of the attacking data flow. Then, the attack tracer receives a first set of results of flow matching based on the flow characteristics from the first service function chain domain. The attack tracer identifies the attack source in the plurality of service function chain domains at least in part based on the first set of results. In this way, the attack source may be traced efficiently in the service function chain overlay network.

Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for protecting MAC addresses. According to embodiments of the present disclosure, the terminal device may obtain a set of virtual MAC addressed from a network device and may connect with a further network device (for example, Wi-Fi AP or Bluetooth devices) using the virtual MAC addresses. In this way, tracking the terminal device with MAC address is prevented so that user privacy protection could be enhanced.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for data sharing. In example embodiments, a method for data sharing is provided. The method comprises, in response to receiving a first request to share data of a user from a data sharing agent, creating a data sharing smart contract for the user. The method further comprises publishing the data sharing smart contract to one or more data consumers. The method further comprises, in response to receiving a second request to access the data from a data consumer, generating, by executing the data sharing smart contract, an indication that the data consumer is authorized to access the data. In addition, the method further comprises sending the indication to the data consumer. In this way, end users are enabled to manage and share their personal data by themselves.

Abstract: Example embodiments of the present disclosure relate to enablement of a service function chain based on a software defined network. In some embodiments, there is provided a method implemented at a service function chain controller. The method comprises creating a service function chain for a packet, the service function chain comprising a set of ordered service functions that are to process the packet; and configuring respective forwarding rules associated with the service function chain directly or indirectly to a plurality of network nodes in a software defined network, the respective forwarding rules indicating how the plurality of network nodes forward the packet to the set of ordered service functions in the service function chain. In this way, it is possible to enable the service function chain in the software defined network.
