On Performance of Concealing-Restoring System for Analog Signals on Physical Layer

We have proposed a concealing-restoring system (CRS), which is for the security of the digital data on the physical layer of the open-systems-interconnection reference model. Primarily, the main body (MB) of CRS shoulders the concealing and restoring of analog signals which should be transformed into the digital data on the physical layer. MB conceals an original, analog signal by the random-noise disturbance, and makes the concealed signals. MB also restores the analog signal from the concealed signals using the proper noise elimination based on the stochastic filtering theory. In this paper, thus, we apply the CRS to analog signals, and briefly report its performance of the restoration. Going through the results of those experiments, we give some mathematical conjectures.
