Cryptography is very important in today’s times as we want confidential information to remain confidential. We don’t want people other than the intended receivers to be able to access our information and if accessed to be able to be able to understand it. Cryptography is the method of converting information to a non-understandable form and then being able to convert it to the understandable form by the recipient. Lightweight stream ciphers are used to reach high levels of security using only a small computing power. Stream encryption is the encryption of each letter one by one followed by the changing the encryption key after each letter. This work presents the design, simulation , synthesis and validation of secure transmission of data( audio, image and text) using rabbit stream cipher algorithm. The rabbit algorithm is implemented using Verilog HDL simulated using Model sim 10.4a synthesis using Xilinx ISE Design Suit 14.2. MATLAB 2014a tool was used to validate the design. To derive implementation results zynq xc7z030-3fbg676 part number was used. the design worked at a speed of 96Mhz..
