Discussion: Cipher
Provide a detailed response to the below to include specific details and examples.
• What is the Vigenère Cipher?
• How does it work?
• Although the Vigenère cipher was an improvement upon previous historical encryption techniques, it is still vulnerable. How would an attacker break a Vigenère-style cipher?
Try your hand!
1. Encrypt the below message using the Vigenère cipher.
• NOW IS THE TIME FOR ALL GOOD MEN TO COME TO THE AID OF THEIR COUNTRY.
2. Decrypt the below message using the Vigenère cipher. The passphrase is ‘crypto.'
• Vyc Kbugecgx Qkgftk kcj btosnfntw pa dyiasorrxvwce Zatwuv bt Owivltks ke rwx 16hj tccmitp
3. Create a Vigenère cipher of your own and see who can crack it! Toward the end of the week, provide the solution to your cipher.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
