This is not required to perform the lab, unless you want to copy files between PCs. In Part 1 of this lab, you connect the PCs and configure IP addresses. If students are not working with a partner, they can perform the parts of the lab where a partner is referenced using their own files.The main goal is to expose students to a common type of encryption/decryption cipher known as Vigenere and to use an application called S-Tools to embed text messages in graphics files. The parts should be performed sequentially, but can be performed independently if necessary, because of time constraints. Note: Students can work in teams of two for this lab. Although not a strong encryption technique, Vigenere serves to illustrate a commonly used encryption and decryption process. Vigenere is an example of a common type of cipher mechanism called polyalphabetic substitution.

The Cisco IOS password encryption service uses a Cisco-proprietary algorithm that is based on the Vigenere cipher.
Create a secret message using the Vigenere cipher and the key.Work with a lab partner and agree on a secret password.Part 3: Create a Vigenere Cipher Encrypted Message and Decrypt It Given an encrypted message, a cipher key, and the Vigenere cipher square, decipher the message.Part 2: Decipher a Pre-encrypted Message Using the Vigenere Cipher Connect the PCs and configure IP addresses.Part 1: (Optional) Build the Network and Configure the PCs There is NO warranty not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.CCNA Security Lab: Exploring Encryption Methods
