摘要： A method and arrangements for enabling authentication of a communication device is suggested, where a network node, capable of operating as an authentication server does not have to store all state related information relevant for a roundtrip of an authentication session. Instead of storing all this information, at least a part of it is provided to the authenticator or the communication unit, for later retrieval in a subsequent response. Based on the state related information provided in the response, the network node is capable of reproducing a state associated with a respective roundtrip. By repeating the mentioned process for a required number of roundtrips, an authentication session can be executed, where less state related information need to be stored at the mentioned network node.

摘要： A Feedback Shift-Register (FSR) enabling improved testing, e.g., Built-In Self-Tests (BIST), is provided. Each cell of the FSR may either be an observable cell, associated with a non-trivial feedback function implemented by a combinational logic circuit, or a controllable cell, having an associated state variable which belongs to the dependence set of exactly one of the non-trivial feedback functions. Each controllable cell is provided with a multiplexer for selecting either a predecessor cell of the controllable cell or a test value as input. Thus, the sequential circuit of the FSR in an embodiment is tested using tests for combinational logic. The disclosed test procedures utilize a minimal set of test vectors and allow detection of all single stuck-at faults in the FSR. The resulting dynamic power dissipation during test can be considerably less than known BIST designs.
