Research On The Technology Of Data Encryption Algoritm Based On FPGA

Data security is becoming increasingly serious,in the Internet age,a lot of personal information,communications privacy,property requires sufficient security measures to ensure that it is not available to others,data encryption is one of the most commonly used method.The development of modern cryptography offers a variety of data encryption solutions,but for various reasons,there are no completely safe encryption algorithm.Therefore,safer,faster encryption method has been the focus of research in cryptography.FPGA based data encryption algorithm,not only can play safety performance hardware,but can further improve the processing speed of data encryption algorithm,which has great significance for engineering practice existing encryption algorithms.From the start the algorithm,I learn encryption algorithm in?depth,and take advantage of better performance AES encryption algorithm,then,I design and implementation it based on FPGA.The main works are:(1)Complete the software simulation about some common block cipher,analysis and comparison of the performance of all encryption algorithms,pick and choose the best performance of the AES encryption algorithm,as the focus of FPGA?based research.(2)Design efficient implementation of AES data encryption algorithms,including the division of the module,the module interfaces and modules inside the core design.(3)Simulation AES encryption algorithm,compared to plain text and decrypted output.The simulation results show that the correct implementation of the AES encryption algorithm does improve the speed of the algorithm.
