  For the unit on Security, in class we will look at distributed security issues in the context of electronic voting systems. You should read the Economist articles (below) by Nov. 28 class. For the homework, you'll need the IEEE Spectrum article (below), the Economist articles, the text Chapter 7, and a few links provided in the description of the assignment.

• Zip file of Economist readings as .htm files. Read these in preparation for the first class after the break. They are enjoyable to read; you shouldn't mind reading them over the break (along with the textbook chapter on Security).
• The Perils of Polling This is the IEEE Spectrum article from October, 2004. (It's a pdf file that is over 3 Mb. For some of you, you'll want to be sure to download it where you have high bandwidth.)
• Electronic Voting Systems -- a study in distributed security These are the slides used in class on Nov. 28, 2006. Those on electronic voting systems are identical to the file below. In front of those are a few slides to highlight overall issues from Prof. Sicker's presentation provided below.
• Distributed Security -- Network Security This is Prof. Doug Sicker's presentation which emphasizes what he believes are the key issues in the Coulouris chapter on Security.
• Electronic Voting Systems -- a study in distributed security, used on Nov. 17, 2005
• Lec 27 Distributed Data
• Information About the Final Think about it before the last class. We'll talk about it then. Feel free to ask questions on the discussion thread at any time.
• Lec 28 & 29 Testing Distributed Software
• Testing for Software Security Briefly summarized in Lec 29; detailed slides left here for students' benefit but not required to know in detail. (This link was broken. Works now. 12/7/06)
