There is no required or suggested textbook in this course, because there is no one book that covers the right material in an up-to-date fashion. Here are some good books about security, in case you're interested.

There are many good books about cryptography, but relatively few good ones about other computer security topics.


Tuesdays and Thursdays, 3:00-4:20 PM, 104 Computer Science.

Homework Policy

Homework will be due at the beginning of class. Late homework will lose 10% of its value for every day of lateness. Homework more than seven days late will not be accepted.

No homework extensions will be given except in extraordinary circumstances (such as documented illness), and then only if the official university procedures are followed.

Unless the assignment explicitly states otherwise, you may not collaborate with other students on the homework. (Of course, if it is a group assignment, you should collaborate within your group!) If you make use of outside sources, you should disclose that fact and cite the sources, as you would in any scholarly work.

Grading Criteria

Grades will be computed by the following formula: 60% homework; 30% exams; 10% subjective factors such as attendance and class participation.
