  • Patent number: 11489680
    Abstract: Device for secure distance measurement being a prover (P) or a verifier (V) comprising: a receiver (R3) configured to receive a receiving signal (RS) with a transmitted message (M) encoded therein, wherein the transmitted message (M) contains a verifying bit sequence (VBS), wherein a bit of the transmission message (M) is transmitted in the transmission signal (TS) by a pulse with a pulse modulation parameter with two pulse states, and a decoder (R2) configured to decode the verifying bit sequence (VBS) from the transmitted message (M) encoded in the receiving signal (RS).

  • Patent number: 11156704
    Abstract: Method for secure distance measurement comprising the following steps: transmitting from a verifier (V) to a prover (P) a challenge message comprising a challenge bit sequence (C); transmitting from the prover (P) to the verifier (V) a response message comprising the response bit sequence (R); verifying, in the verifier (V), the response message on the basis of the response bit sequence (R); and determining, in the verifier (V), the distance between the verifier (V) and the prover (P) on the basis of the time difference between the challenge message and the response message.

  • Patent number: 9941926
    Abstract: Apparatus for determining a time of arrival of a message signal comprising: a quadrature mixer (13, 14) for mixing a received message signal with the signal of a local oscillator, wherein the received message signal comprises a binary sequence modulated by binary frequency shift keying with pulses corresponding to a first value at a first frequency and with pulses corresponding to a second value at a second frequency, wherein the local oscillator has a frequency between the first frequency and the second frequency; a time of arrival detector (18) for determining a time of arrival of the message signal on the basis of the output of the quadrature mixer (13, 14).

  • Publication number: 20140082696
    Abstract: The method for communicating between a first device and a second device, the first and second devices being structured and configured for communicating via a communication channel by exchanging messages, comprises the steps of a) the first device transmitting a challenge message to the second device; b) the second device, in reaction to receiving the challenge message: b1) carrying out a processing on the received challenge message; b2) generating a response message, said response message being derived in dependence of said challenge message; and b3) transmitting the response message to the first device; c) the first device receiving the transmitted response message and determining a time elapsed between the transmitting of the challenge message and the reception of the response message; d) the first device computing, in dependence of said determined time, of a value indicative of a travelling speed of the challenge and the response messages and of a value indicative of a processing time assumed to be req

  • Patent number: 8407162
    Abstract: The present invention relates to an arrangement for network management and adapted to be provided in or associated with a network node to be managed. It comprises, or is in communication with, modeling means adapted to, using substantially non-formal descriptions, model network domain and behavior using formal ontologies comprising inference capabilities by means of an inference engine, thus providing a formal ontology model describing domain and behavior. It also comprises annotating means adapted to add semantic information to the formal domain and behavior ontology model, generating means adapted to, using said formal ontology model and said inference engine, elaborate an algorithm adapted to generate and update a probabilistic causal network graph structure representing the domain and its behavior.
