Encryption and Decryption using optimized Reconfigurable Reversible Gate

In today’s technologies the power dissipation, delays, size, and heat are the toughest challenges to overcome in IC industries. If the computing element’s size is minimized, we can speedup the process and if the power loss is reduced, the heat dissipation will also be less. The preferable solution for these difficulties is the method of reversibility and QCA. The reversible computing is ever promising technology for the upcoming quantum computing technologies. The RLGs will decrease the power loss to a large extent, ideally to zero. If it is practically developed as an IC, then the complete world of electronic devices must be replaced, this initiates the new generation of the electronic world. This paper explains an application of reconfigurable logic, Encryption of data, Decryption of the same data implemented using Verilog coding. The design is verified through Xilinx Vivado software and the optimized delay is observed. The Encryption and Decryption process(E&D) is verified by the Simulation results.
