FPGA Implementation of 256-Bit Key AES Algorithm

Abstract: The most popular network security technique for secure data transmission between two end users, particularly over a public network, is the AES algorithm, also known as the Rijndael algorithm. It may be found in all kinds of wired and wireless digital communication networks AES, a network security technique, uses 256 bits on an FPGA. An authorized cryptographic technique that can be used to secure electronic data is the Advanced Encryption Standard technique (AES), which is specified by the National Institute of Standards and Technology. Because they provide faster and more flexible solutions, reprogrammable devices like Field Programmable Arrays (FPGA) are a very appealing alternative for hardware implementation of the encryption algorithm AES. The effective FPGA implementation of advanced encryption standards (AES) is proposed in this research. The encryption code is written in the Verilog programming language. The AES Rijndael algorithm performs better than any other when implemented on FPGA. Other works are covered by this implementation to demonstrate its effectiveness. The block and key sizes in the design are 256, and an iterative looping technique is used. Bits, S-box implementation using lookup tables. This results in a low-complexity design that can readily achieve high throughput and low latency
