CNSS/NSTISSI Mapping: n/a

Abstract:
This lab is designed to expose students to some introductory principles of cryptography as they relate to hashing or the hash function. Specifically, the students will create digital signatures or fingerprints for information sources and then observe the behavior of the fingerprints when the integrity of the sources is compromised. The students will also have the opportunity to compare different hash functions and audit some of the results.

Requirements:
The lab uses the Windows XP operating system running on VMWare Workstation along with hash creation software.

CNSS/NSTISSI Mapping: n/a

Abstract:
Ever wanted a way to send private information to a friend or partner that is secure and easy to do? This lab presents to the student a mechanism to do just that by concealing a message in a bitmap (bmp) file. The student will also be able to consider additional transports, or carriers such as other image or audio formats.

Requirements:
The lab uses the Windows XP operating system running on VMWare Workstation along with some custom files and a 'stego' tool.

Revised: Joel Nunes, Alessandro Seazzu, June 2007

CNSS/NSTISSI Mapping: n/a

Abstract:
This lab is designed to show student how public-key cryptography may be used through the GnuPG software to encrypt and decrypt data. Students will generate their own key pair and use them on a file they create. They will observe what encrypted and decrypted data look like.

Requirements:
In this lab you will use VMWare to host a session of Windows XP which can be reverted after the lab is completed along with some custom files and a tool which implements public-key cryptography. The software and tools required for this tutorial(s) are open source, freeware, shareware, trial version or a combination thereof. It is recommended that the user take a few minutes to read the entire tutorial before starting any computer interactions.

Author: Alex Zamora and Marisa Vargas, Spring 2007
Revised: Joel Nunes, Alessandro Seazzu, June 2007

CNSS/NSTISSI Mapping: n/a

Abstract:
If you want to have a truly secure file, using Truecrypt is the only way to prevent others from decrypting your file. This lab was designed to present the use of the Truecrypt software to encode a secret message.

Requirements:
In this lab you will use VMWare to host a session of Windows XP which can be reverted after the lab is completed along with some custom files and a tool which implement the AES Block cipher.

Intro to Cryptography - PGP

Authors: Elizabeth Garcia, Spring 2005
Revised by: Joel Nunes and Alessandro Seazzu, Summer 2007

CNSS/NSTISSI Mapping: n/a

Abstract:
The purpose of this lab is to demonstrate the encryption/decryption process of a file. You will use PGP Desktop for Windows. PGP Desktop is a tool for keeping your data safe. It encrypts your data so that if an unauthorized person gains access to it, they are unable to use the data. When you need to use the data, you can decrypt it using PGP once the verification process is completed.

Requirements:
The lab uses the Windows XP operating system running on VMWare Workstation along with hash creation software.

Intro to Frequency and Crypto Analysis

Authors: Hue Lai, Bill Scholl, Fall 2007
Revised by: Hue Lai, Spring 2008

CNSS/NSTISSI Mapping: n/a

Abstract:
This lab is designed to show students how to use frequency analysis software. Once the message letter frequency is determined, students will use the material from the research section to aid in acquiring the original message. The students will use an online application to decipher the message.

Requirements:
In this lab you will use VMWare to host a session of Windows XP which can be reverted after the lab is completed along with some custom files and some software to analyze letter frequencies in a message and to encode/decode the message. The software and tools required for this tutorial(s) are open source, freeware, shareware, trial version or a combination thereof. It is recommended that the user take a few minutes to read the entire tutorial before starting any computer interactions.
