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...

Problem 1: Forging a blockwise MAC We saw in class that vanilla AES is an unforgeable message authentication code (MAC).. as long as each message is only one block long. In this problem, your task is to forge a MAC when we apply AES separately to each block (separately) of long messages. Below, I include three messages in ASCII along with their blockwise AES encipherings in hex. You don't know the key. ai = ‘Deposit amount: 5 dollars, ti =...

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...

Implement in Go language AES encryption mode CBC with providing the packages name for Go language. You can implement AES-ECB Mode (the basic AES) from crypto/aes package and crypto/cipher.Block. You can also get the SHA-256 hash function from crypto/sha256. You can get the secure random numbers generator from crypto/rand package. However, the you will implement both CBC mode and HMAC from scratch. You are NOT allowed to use any libraries or packages to implement these two things for you. You...
