摘要： A sender and a receiver includes first and second arrays of coupled oscillators, respectively, that are substantially identically constructed so as to exhibit substantially the same dynamical response to excitation. A chaotic waveform generated at the sender is transmitted to the receiver, which generates a second chaotic waveform, and compares the received waveform with the generated second waveform. If the first and second waveforms match the sender is an authorized sender. An integrated circuit includes an array of coupled oscillators that in combination generate a waveform in response to at least one excitation signal. The array of coupled oscillators represents, in response to application of the excitation signals, a multi-dimensional security key that is shared between the sender of the waveform and the receiver of the waveform.

摘要： A method of communication between a first node and a second node for a system where a plurality of different channels is provided between said first and second node. The method comprises the step of calculating an integrity output. The integrity output is calculated from a plurality of values, some of said values being the same for said different channels. At least one of said values is arranged to comprise information relating to the identity of said channel, each channel having a different identity. After the integrity output has been calculated, Information relating to the integrity output is transmitted from one of said nodes to the other.

摘要： The invention relates to a method for ensuring data transmission security between a first and a second communication device in short-range wireless communication. To set up a secure data transmission connection, the communication devices conduct a key exchange stage to generate at least one shared key between the communication devices. After said key exchange stage at least a first and a second check string is formed, said strings being based at least on a unique short random string and on the keys generated in each communication device at said key exchange stage. Thus, the security of the connection that is set up is ensured by comparing the correspondence of said check strings. The invention also relates to a communication system and a communication device, in which the method will be applied.

摘要： A method for protecting traffic in a radio access network connected to at least two core networks. The method comprises maintaining a corenetwork-specific authentication protocol and a radio-bearer-specific ciphering process, and generating, for each ciphering process, a count parameter comprising a cyclical sequence number and a hyperframe number (HFN) which is incremented each time the cyclical sequence number completes one cycle. For each core network or authentication protocol, a first radio bearer of a session is initialized with a HFN exceeding the highest HFN used during the previous session. When a new radio bearer is established, the mobile station selects the highest HFN used during the session for the core network in question, increments it and uses it for initializing the count parameter for the new radio bearer. At the end of a session, the mobile station stores at least part of the highest HFN used during the session.
