Advanced Encryption Standard

The Advanced Encryption Standard (AES) is a symmetric block cipher to encrypt sensitive data. This implementation supports a 128-bit key. AES-128 bit requires 10 rounds to complete the full operation. The input data is 128 bits and the input key is also 128-bit and each round requires 1 cycle to complete.

• Substitute bytes

• Shift rows

• Mix columns

Building on macOS

1. Icarus-Verilog can be installed via Homebrew : $ brew install icarus-verilog

2. Download Scansion from here.

3. Clone the repository.

4. Run $ make and type MIPS code to see it in binary form in rams_init_file.hex file.

5. $ make simulate will:

• compile design+TB
• simulate the verilog design

6. $ make display will:

• display waveforms.
