Abstract: There is provided a process for a blockchain, BC, consensus verification, comprising steps of receiving a transaction comprising sensor data on an event and a position data of a sender node of a blockchain network, selecting a number of nodes of the blockchain network as validating nodes based on their position data and the position data of the sender node, sending a new block to the blockchain network, wherein the new block is based on the received transaction, receiving labels assigned to the new block from the validating nodes, and verifying the received labels with a consensus protocol.

Abstract: Method, apparatus, and computer program are disclosed for operating drones or other mobile computers in sensitive environments, where the drones are exposed to attacks with updates, incorrect/malicious commands or even being joined by malicious drones pretending to be part of the drone swarm or group. The method includes leveraging both trusted computing capabilities and that each individual drone can decide on the level of assurance and trust of any other drone we can construct a consensus algorithm such that if a drone wishes to perform a sensitive operation then all drones can attest that drone and decided on its level of assurance.

Abstract: A first network device for use in a blockchain network is described. The first network device comprises
means for, while carrying out a first iteration of a consensus protocol involving a second node device (103), in response to a trigger event (3040), obtaining a time interval function of a time interval start trigger event (3040) and of a time interval end trigger event (3080), each event being linked to a message of the consensus protocol and wherein at least the end trigger event (3080) comprises receiving a message from the second node device; means for transmitting (3083) first data (Delay_102) representative of said time interval to said second node device; means for, during a subsequent iteration of said consensus protocol involving said second node device, receiving a message (3140) from said second node device, said message containing second data (DelayTX_102) representative of said time interval from said second node device; means for authenticating said second node device as a function of said second data. A second network device, methods at the first and second network devices and a computer readable medium with code for carrying out the methods are also described.

Abstract: For securing a provable resource possession on a host device having spawned a set of virtual machines providing services to a client device, the client device is able to send a challenge request to each virtual machine, the challenge request containing a physically unclonable function (PUF) challenge and a filter rule; receive a PUF filtered response from each virtual machine, the PUF filtered response being a PUF response that is filtered according to the filter rule and obtained by challenging; combine the PUF filtered responses into a reconstructed PUF according to the filter rule; and if the reconstructed PUF corresponds to an expected response in the challenge-response database, validate that the set of virtual machines is effectively running on the right host device.

Abstract: An apparatus and method are provided for monitoring a behavior of a communication device by using network controllers and network manager. The communication device is included in a network comprising a set of communication devices and a network manager allowing access by the communication devices to a communication network. A communication device may send a broadcast message to available network controllers and a network manager. The communication device may also send a service request to the network manager, the service request being routed by the network manager to a communication network and sent in broadcast by the network manager to the network controllers. Using the service request as the basis for a first report on behavior of the communication device, the communication device may additionally verify the first report by a report by network controllers based on the service request received from network manager.
