Homework Answers
This is the S box used in AES for byte substitution. (Rijndael S box)
Given Number-> 0100100
This is 7 bit number, make it 8 bit-> 0010 0100
Convert it to Hex
0010 is 2 in hex
0100 is 4 in hex
0010 0100 is 24 in hex
Look at 2nd row and 4th column of above table ( first digit of hex corresponds to row and second to column)
Output=7d
Convert it back to binary
7=0111
d= 13 in decimal = 1101
Ans=0111 1101

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...

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...

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 =...
