In the field of Nanotechnology, Quantum-dot Cellular Automata is a new nascent technology. In order to overcome the CMOS limitations, less area and low power consuming QCA circuits are designed. Cryptography in QCA has been used to provide high data security during transmission. When comparing with symmetric cryptography, Asymmetric cryptography are confidential and authentication. In our paper, we designed a Public key cryptography using RSA algorithm that encrypts and decrypts the data using different keys. We also designed a full adder circuit with less area and latency when compared with previous works. The proposed architecture has been design and tested using QCA Designer tool.
