AES algorithm is a Block cipher and works on fixed-length group of bits, which are called Blocks. It takes an input block of 128 bits, and produces a corresponding output block of the same size. AES requires a second input, which is the secret key. AES uses three different key sizes: 128, 192 and 256 bits. Adding a Round Key to the State.

Block diagrams are used to represent technical systems in a range of applications, including: Dynamic systems : Simulate virtual models of dynamic systems to evaluate design decisions. Control logic : Develop, test, and validate control algorithms before deployment.

AES-inspired ASCII-based text encryption and decryption ; MATLAB-based; Converts text to a matrix table and vise-versa. GUI created using GUIDE; All steps broken down into separate .m files

In this paper, we compare AES encryption with two different S-Boxes: S-box with 256 byte lookup table (Rijndael S-Box) and AES with 16 byte S-Box (Anubis S-Box). Optimized and synthesized VHDL code is used for AES encryption. Xilinx ISE 13.2i software is used for VHDL code implementation and Modelsim simulator is used for the simulation.

A MATLAB code is developed for plaintext encryption and cipher text decryption. Experiments are conducted to measure the execution times. The measured results indicate a maximum encryption time of 87 ms and decryption time of 88 ms.

In this paper, Image Encryption and Decryption using AES algorithm is implemented to secure the image data from an unauthorized access. A Successful implementation of symmetric key AES algorithm is one of the best encryption and decryption standard available in market. With the help of MATLAB coding implementation

For each block ciphers, two files are provided: (Cipher)_lib.m and (Cipher).m (Example: LILLIPUT_lib.m and LILLIPUT.m). The first file contains the library of all function used in the block cipher implemented. The second file encrypts and decrypts messages. 2. …
