SEED Labs $$ Secret$-$Key Encryption Lab $1$ Secret$-$Key Encryption Lab

$1$ Overview

The learning objective of this lab is for students to get familiar with the concepts in the secret$-$key encryption and some common attacks on encryption. From this lab, students will gain a first$-$hand experience on frequency analysis, encryption algorithms, and encryption modes. Moreover, students will be able to use tools to encrypt$/$decrypt messages.

Many common mistakes have been made by developers in using the encryption algorithms and modes. These mistakes weaken the strength of the encryption, and eventually lead to vulnerabilities. This lab exposes students to some of these mistakes, and ask students to launch attacks to exploit those vulnerabilities. This lab covers the following topics:
