Cryptography 2007 - Errata

• Handout 11, page 79, point 81: The last line should read:
  ... encrypt the information with the public key and only publish the private key once the information needs to be verified by Bob.
• Handout Quantum Cryptography, page 5, paragraph 2: The second complexity should read:
  O(n² log n log(log n))
• Handout Quantum Cryptography, page 3, paragraph 2: The sentence starting with "In essence" should read:
  In essence, it allows computations to be performed on many numbers at the same time ...
• Handout 9, page 67, last line should read:
  Compute M₁⋅ M₂ = C₁^d⋅ C₂^d = C₁^d⋅ C^d⋅ C₁^-d= = 1⋅ C^d= M^ed= M.
• No marks were given on the original Exercise Sheet 9. This has been corrected. See the updated handout for the marks.
• Programming Exercise 1, 19: In the MixColumn Operation it should read i=0,1.
• Exercise Sheet 3: The exercise should be number 13 and 14 instead of 1 and 2.
• Solutions 1, 4b: should read [7]₈ + [7]₈ = [6]₈.
• Solutions 1, 1: The ciphertext is actually WIUEHUHNBLETEDTLTHNOTTR.
