• Coursework. Coursework will consist of homeworks, class presentations, and a course project. The overall grade will be determined 35% from homeworks, 25% from the midterm, and 40% from the final exam. Group work on homeworks is permitted, but each student must list his or her collaborators in writing for each problem. If a student turns in a solution without listing the others who helped produce this solution, this act will be considered cheating (for it is plagarism). (See the ICS Cheating Policy.) Late homework assignments will not be accepted.
  
• Text. Pieprzyk, Hardjono, and Seberry, Fundamentals of Computer Security
• Add/drop policy. All drop requests should be given to Prof. Goodrich at office hours or by appointment. Drops will be accepted only up to the fourth week. Once your drop card has been signed, further coursework from you will not be graded. After the seventh week of classes, withdrawals will be allowed only by petition and under documented extenuating circumstances, in accordance with ICS departmental policy.
