Discretionary access control (DAC) is the kernel of most protection mechanism, and the research on safety of DAC concerns whether rights can be leaked to unauthorized subjects.
This paper presents a DAC dynamic test instrument which display DAC output waveform of any division open loop VHF number generator used in the broadband oscilloscope.
