Parallel-AES-Algorithm-using-CUDA

This project parallelized the process of AES encryption with CUDA. We can enhance the overall speedup to 3 times than the original serial version.

AES program first encrypt the input file with the user-defined key file. Then, to check the correctness of our encryption, we decrypt the encrypted file using the same key file.

Compile using Makefile

make

Run

Usage:

./AES [file to encrypt] [key file] [filename of encrypted file] [filename of decrypted file]

For example, you can try encrypting provided "novel.txt" file with "key.txt" as a key file:

./AES novel.txt key.txt encrypt.txt decrypt.txt

• encript.txt will be the result of encryption from novel.txt
• decrypt.txt will be the result of decryption from encrypt.txt.
