A new secure image communication system has been
designed and implemented based on a synchronized chaotic circuit. The new
chaotic circuit, which has recently proposed by one of the authors contains a
resistor, two inductors, and two diodes (i.e. R2L2D). The synchronization part
operates with a master – slave configuration. In order to achieve the real-time
communication, initially the analog master circuit has been implemented to
generate chaotic sequences of numbers. Then, that analog tool has been transmitted
to a computer via an analog/digital converter and a hidden image has been
obtained. Besides, the slave circuit has also received a copy of that chaotic
sequences in order to use it in subtraction process of image gray levels. The
digital chaotic image has been transmitted to the slave circuit via a
digital/analog converter with an efficient method and the decrypted image has
been obtained in real-time. The advantage of that technique over the
conversional ones is that it does not require any saved copy of the digital
data, even for sending them in gray images to the receiver, since it is
real-time. The conventional techniques use the stored and processed data and
that can cause security problems in today’s advanced web media. Thus to send
the encrypted image in a real-time device by using an analog chaotic equipment
has certain security superiority. The analyses on the preliminary decrypted
images proves that the process is efficient in time and secure.
