FPGA IMPLEMENTATION OF ADVANCE ENCRYPTION STANDARD WITH SINGLE KEY

Advanced encryption standard (aes), is known as most secured encryption standard now a days. many researchers have implemented it in different languages like java, c and c++ with different algorithms. recently the aes 128-bit has been implemented using verilog on fpga with equipped key being encrypted along with data input in whole process. in this paper the aes 128-bit encryption and decryption process with key which is only used for data input and is not encrypted throughout the encryption/decryption process. results are same but our algorithm is slightly faster because only data is encrypted in the process of encryption, thus process time and area is optimized.
