The Advanced Encryption Standard (AES) is the most widely used symmetric block cipher today. The AES block cipher is also mandatory in several industry standards and is used in many commercial systems. Among the commercial standards that include AES are the Internet security standard IPsec, TLS, the Wi-Fi encryption standard IEEE 802.11i, the secure shell network protocol SSH (Secure Shell), almost all internet browsers like Google Chrome, Firefox, etc. and numerous security products around the world. To date, there are no attacks better than brute-force known against AES.
In this repository, we have focused on understanding the underlying steps in the AES encryption algorithm, take a look at the PN sequence based S-box and key generator and finally implemented the algorithm in Verilog and tested the implementation using NIST's AES standard test blocks in ECB mode.
