Assignment:
Description
Review the following LinkedIn Learning videos to help you with your assignments in this Unit.
There are two parts to this assignment. Part 1 involves the encryption/decryption scenario below and Part 2 requires research on the classification of ciphers, and popular algorithms.
Part 1
Use a two stage transposition technique to encrypt the following message using the key "Decrypt". Ignore the comma and the period in the message.
Message: "The Transposition cipher technique works by permuting the letters of the plaintext. It is not very secure, but it is great for learning about cryptography."
In a 2 to 3 page summary, discuss the following:
Is it possible to decrypt the message with a different key? Justify your answer.
Do you agree with the statement of the message? Why or why not? Give at least two examples that support your view.
Part 2
Provide a 1 to 2 page researched responses to the following:
Research and provide a detailed meaning for at least three techniques in which encryption algorithms can produce ciphertext. Pick at least 3 from the cipher list below:
- Monoialphabetic
- Steganographic
- Polyalphabetic
- Polygraphic
- Route transposition
- Columnar Transposition
- Synchronous Stream
- Asynchronous Stream
Please submit your assignment.
For assistance with your assignment, please use your text, Web resources, and all course materials.
Read selected articles from the AIU Library as identified in the Learning Materials.
