Grading: The course grade will be based on 3 problem sets (total 30%), a midterm (30%), and a project (40%).

Problem sets:  PS1 [Word], PS2 [Word], PS3 [Word].

Solutions sketch: PS1 [Word], PS2 [Word], PS3 [Word].

Problem sets are due at the beginning of class. As a general rule the penalty on a homework turned in upto a week late will be 20% and no homework will be accepted beyond 1 week past its due date. Students may discuss the problem sets with one another, but solutions should be written up separately. If a key idea is obtained from another person (other than the TA or the instructor) or from another book or paper (other than the course textbook), then the source of that idea should be cited. Solutions should be presented in a clear and concise manner.

Midtem: The midtem will take place on February 11th. Please mark your calendars and make sure that you will be able to attend the midterm.

Project presentation: The project presentation will take place during finals week.

Project selection: students can either propose a project and get the agreement of the instructor and choose a project from [ProjectsDescription]. Projects will include: setting up and evaluating VPN networks, and monitoring tools, investigating the security of IEEE802.11 WEP, implementing a secure mulitcast protocol of wireless ad hoc networks, and development of secure instant messaging system.
