Differentiate between Symmetric and Asymmetric cipher. Encrypt the message 'HELL' using the key 'FAIL' using Vernam cipher. [5]
- Plaintext: HELL - Key: FAIL - Cipher: Vernam cipher - Letter mapping used: $A=0, B=1, \dots, Z=25$ --- Feature Symmetric Cipher Asymmetric Cipher --------- Keys used Single shared secret key for both encryption and decryption Two keys: a public key and a private key Key distribution Difficult; ...
