Problem
(a) Using Vigenère cipher and given the key abc, find the ciphertext for the message:
simplicity
Only the 26 lower-case alphabetical characters are used in messages.
(b) Compare and contrast Data Encryption Standard (DES) with Advanced Encryption Standard (AES) with respect to:
(i) their classification (ii) their encryption/decryption structure and algorithm (iii) their cryptographic strength (iv) types of attacks (v) hardware/software implementation
(c) Consider a Diffie-Hellman scheme with a common prime q = 11 and a primitive root α = 2.
(i) If user A has public key YA = 9, what is A's private key XA? (ii) If user B has public key YB = 3, what is the shared secret key K, shared with A?
(d) What are the characteristics of the ‘one-time pad' cryptosystem as compared to Vigenère Cipher.
Give one advantage and two problems with one-time pad cryptosystems.
