In this paper, a system for the purpose of signals encryption using the technique of independent component analysis has been proposed.The proposed system mixes the original signal with arbitrary number of random signals in order to obtain a highly encrypted signal like noise.The number of random signals is indicated by an attached key signal preceding the encrypted signal.In order to increase the encryption strength, the number of random signals is changed at each signal transmission.An independent component analysis technique is utilized to separate signals and select the original signal by a designed selector.A set of parameters has been adopted to measure the encryption quality and decryption capability.Promising encryption results represented by up to -48.35 dB for segmental spectral signal to noise ratio and 0.00037 correlation coefficient between the original and the encrypted signals are obtained.As well, an efficient signal decryption is achieved with 45.85 dB signal to noise ratio and nearly 1 correlation coefficient value between the original and reconstructed signals.In conclusion, the proposed system is a good candidate to be adopted in developing highly reliable security transceiver systems.
