AES Encryption M = 2C58FD04C2D8DB1928E11849B997044E K = 8EF8553B444EC546F3AAAF56287AB13F Assignment: AES Encryption This assignment familiarizes you with AES encryption. We are given a 128-bit message M 2C58FD04C2D8DB1928E11849B997044E (in hexadecimal) and a 128-bit cipher-key K 8EF8553B444EC546F3AAAF56287AB13 (also in hexadecimal). Using AES encryption scheme discussed in class, find the following values. Write your answer in hexadecimal (capital letter) without inserting any space between hexadecimal digits (for example, write "9F2C", not "9f2c" or "9F 2C") 1. In Round 1 of the encryption process, what...
c programming Problem 2 Write a Hexadecimal to Decimal converter. Program will take an input (hexadecimal number) from user and display its corresponding decimal number, as an output, on the screen.

Part 1 – Data Encryption Data Encryption is the process of transforming data, using a cipher, to make it unreadable to anyone except those possessing special knowledge. In this problem you will implement a simple encryption technique on data that comprises of non-negative integers that have at least six digits with no leading zeroes. In order to encrypt the number the following functions are to be implemented: void input(int *num); int add4(int num); int shift(int num); void printOutput(int encryptNum, int...
Background: For this assignment, you will write a small encryption utility that implements a simple encryption algorithm described below. The program will take one command line argument as an input; this will represent the word which is to be encrypted. As an output, your program will print the encrypted version of the word to the console using a simple printf() statement. This is the only output your program needs to produce. There is an important catch, however: your program is...
Create the logic diagram for this circuit Create a binary to hexadecimal converter. Use SW3-0 as the input and the left most 7 segment display ONLY as the output. SW3-0 should be interpreted as a 4bit unsigned binary number with SW3 as the MSB. The 7 segment should display 0-F based on the input number, both upper and lower case may be used. You need to show to the marker: Create a binary to hexadecimal converter. Use SW3-0 as the...
Final Project-1 A Modified XTS-AES Encryption and Decryption Input File: input. and key txt Time Limit: No Problem Description Advanced Encryption Standard (AES) is a well-known symmetric block cipher in modern cryptography. It was published by NIST in 2001. Here, we design a modified XTS-AES as shown in Fig. 1. Please write two programs for encryption and decryption (e.g., encrypt.cpp and decrypt.cpp). To test the correctness of your encryption and decryption, two samples (one 256-bit plaintext and one 192-bit plaintext...
