This paper describes an overview of data security algorithms and its performance evaluation. AES, RC5 and SHA algorithms have been taken under this study. Three different types of security algorithms used to analyze the performance study. The designs were implemented in Quartus-II software. The results obtained for encryption and decryption procedures show a significant improvement on the performance of the three algorithms. In this paper, 128-bit AES, 64-bit of RC5 and 512-bit of SHA256 encryption and Decryption has been made using Verilog Hardware Description Language and simulated using ModelSim.
