PY 2004 BP 245 EP 266 VL 99 DI 10.1016/j.entcs.2004.02.011 AB We define a probabilistic model for the NRL Pump and using FHP-mur$\varphi$ show experimentally that there exists a probabilistic covert channel whose capacity depends on various NRL Pump parameters (e.g. buffer size, number of samples in the moving average, etc).
