Image Steganography isa method of concealment secret information, by embedding it into a video, image. It is one in every of the methods employed to protect secret or sensitive information from malicious attacks. Here we are consider secure image data transmission through secure nano-scale communication circuit, Quantum-dot cellular automata (QCA), could be a new paradigm that replaces CMOS circuits by victimization the charge configuration. QCA is used to design the modern digital circuits at the Nanoscale. Thus, using QCA to implement the proposed design reduces 28.33% of area compared with CMOS implementation. When we consider the features of QCA nanotechnology, it performs well low power dissipation and nano scale size at high frequency is exploring as a emerging technology to replace CMOS based systems. The technology behind the QCA Feynman, Toffoli, and Fredkin universal reversible logic gates circuits in the base are implemented and analyzed. In order to optimize the design QCA technology extend up to 5-input majority gates and use a F-Gate. We are proposed reversible XOR gate like Feynman gate as an Encoder/Decoder circuit. Further consider the benifits of QCA the proposed circuit is encoder circuit is also used for reverse computing to encode the data and to use the LSB technique in the image pixels for secure nano communication circuit. We estimated the area and latency of the QCA circuit

In recent years Quantum-dot Cellular Automata (QCA) has been considered one of the emerging nano-technology for future generation digital circuits and systems. QCA technology is a promising alternative to Complementary Metal Oxide Semiconductor (CMOS) technology. Thus, QCA offers a novel electronics paradigm for information processing and communication system. It has attractive features such as faster speed, higher scale integration, higher switching frequency, smaller size and low power consumption compared to the transistor based technology. It is projected as a promising nanotechnology for future Integrated Circuits (ICs). A quantum dot cellular automaton complex gate is composed from simple 3-input majority gate. In this paper, a 8-3 encoder circuit is proposed based on QCA logic gates: the 4-input Majority Voter (MV) OR gate. This 7-input gate can be configured into many useful gate structures such as a 4-input AND gate, a 4-input OR gate, 2-input AND and 2-input OR gates, 2-input complex gates, multi-input complex gates. The proposed circuit has a promising future in the area of nano-computing information processing system and can be stimulated with higher digital applications in QCA.

Quantum Dot Cellular Automata

The miniaturization of electronic devices and the inefficiency of CMOS technology due to the development of integrated circuits and its lack of responsiveness at the nanoscale have led to the acquisition of nanoscale technologies. Among these technologies, quantum-dot cellular automata (QCA) is considered one of the possible replacements for CMOS technology because of its extraordinary advantages, such as higher speed, smaller area, and ultra-low power consumption. In arithmetic and comparative circuits, XOR logic is widely used. The construction of arithmetic logic circuits using AND, OR, and NOT logic gates has a higher design complexity. However, XOR gate design has a lower design complexity. Hence, the efficient and optimized XOR logic gate is very important. In this article, we proposed a new XOR gate based on cell-level methodology, with the expected output achieved by the influence of the cells on each other; this design method caused less delay. However, this design was implemented without the use of inverter gates and crossovers, as well as rotating cells. Using the proposed XOR gate, two new full adder (FA) circuits were designed. The simulation results indicate the advantage of the proposed designs compared with previous structures.
