Cryptography 2008 - Errata

• Solutions Sheet 2, Exercise 8 (b): The ciphertext should C=01011001 both as output of the encyption algorithm and input for the decryption algorithm
• Solutions Sheet 2, Exercise 7 (c): This should read “28 corresponds to 011100...”
• Exercise Sheet 2, Exercise 8: The key schedule should read K₀=K, K_i=C_iD_i, i=1,2,...
