java program AES 128

Java program AES-128 bits Specifications: you are required to write the java program “[login to view URL]” to implement the block cipher AES-128. Specifically, your program will read parameters, key, plaintext and ciphertext from a file named “[login to view URL]” (under the same directory of the program). Then your program should create a file named “[login to view URL]” (under the same directory of the program) and write the encryption and decryption results to “[login to view URL]”. Please check the attached sample files “[login to view URL]” and “[login to view URL]”. In “[login to view URL]”: 1. First line is the coefficients of an irreducible polynomial m(x) (degree is 8) over Z2, from the leading coefficient to the constant term, separated by one blank space. 2. Second line is the key (in hexadecimal format, 32 digits, without blank space). 3. Third line is the plaintext (in hexadecimal format, 32 digits, without blank space). 4. Fourth line is the ciphertext (in hexadecimal format, 32 digits, without blank space). In “[login to view URL]”: 1. First line is the ciphertext (encryption result of the plaintext in [login to view URL]). 2. Second line is the plaintext (decryption result of the ciphertext in [login to view URL]). Testing : You are required to turn in a single java file “[login to view URL]”. It will be tested using command line. First, the files “[login to view URL]” and “[login to view URL]” will be placed under the same directory.
