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.

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.
