[edit] Q&A

we'll start the session going over the topics we've left out in the previous session:


  • (chapter 1) p21 index of coincidence
  • (chapter 1) image based example of vernam cipher (todo: code this in python or language of yr choice)
  • (chapter 2) p43 OFB (output feedback)

we will also have a small discussion on Shannon's secrecy theory (section 1.3)

[edit] progress

then we'll go on reading chapter 2 of the s.vaudenay book; (please prepare these, for sure if you want to join in, but missed the first session)

[edit] later that evening
