A wireless device ( 100 ) includes an electrical circuit arrangement ( 200 ) for deterring access to an electrical signal having a predictable electrical pattern. The circuit arrangement ( 200 ) includes a processor ( 206 ) for processing instructions and a controller ( 210 ) communicatively coupled to the processor ( 206 ) and able to send at least one signal along each of a plurality of signal lines from within the circuit ( 200 ). The processor ( 206 ) causes the controller ( 210 ) to sporadically introduce a signal onto each of the plurality of signal lines, where the signal is unrelated to any communication function of the wireless device and is present solely for the purpose of making the signal line unpredictable.
