    Abstract: In one embodiment, a primary server receives, from a client device, a first request to mitigate an external attack on the client device. The primary server sends, to a plurality of secondary servers, a second request to mitigate the external attack, wherein each one of the plurality of secondary servers has associated mitigation resources, and receives from at least one of the plurality of secondary servers an indication that it has mitigation resources capable of mitigating the external attack. The primary server sends, to the client device, a list including the secondary servers having mitigation resources capable of mitigating the attack, and receives, from the client device, an indication that a subset of the list is selected to mitigate the external attack. In response, the primary server sends a request for mitigation services to one of the secondary servers in the subset selected to mitigate the external attack.

    Abstract: In a mobile network, an identity of a security group associated with user equipments (UEs) may be obtained. A segment route (SR) path for session communications in the mobile network for the UEs may be selected based on the identity of the security group. The SR path may be one of a plurality of SR paths in a transport network used by the mobile network and defined at least in part by one or more segment IDs (SIDs). An identity of a virtual network associated with the security group may also be obtained. The selected SR path and the identity of the virtual network may be provisioned in one or more routers of the transport network, such that IP messages communicated for the UEs in the mobile network are forwarded via the selected SR path and (at least ultimately) via the tunnel associated with the security group.

    Abstract: Various implementations disclosed herein enable blockchain programming in NB-IoT devices. In various implementations, a method of blockchain authentication is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations, the method includes maintaining a blockchain for a machine-to-machine network, wherein the machine-to-machine network is a narrowband internet of things network. In some implementations, the method includes receiving a request for a first set of data from the blockchain by a second device. In some implementations, the method includes determining based on the request, the first set of data from the blockchain by traversing a series of blocks from the blockchain. In some implementations, the method includes packaging the first set of data from the blockchain according to a protocol into a packaged data unit and transmitting the packaged data unit to the second device.
