** Text: ** "Introduction to Cryptography" by
W.Trappe and L.Washington.

** Exams**:
There will be a midterm exam and a
final exam.

** IMPORTANT CHANGE **: The midterm exam has been rescheduled and will take place on
**Wednesday, March 23; **

The University has scheduled the final exam for
**Wednesday, May 11 from 2:00 - 4:00 pm. **
The midterm will be worth 100 points and the final exam will be worth
200 points.

**Homework:**
Homework will be assigned
regularly. Selected homework will be
graded and a final score equivalent to one test, 100 points, will be
assigned.
Homework is an essential component of the course.

** Software:** Many homework assignments will involve tasks, such as manipulating large numbers, that are only reasonable to do with a computer. Thus students will need to have access to a computer and a suitable software package. The following packages are highly recommended: Mathematica, Maple, Matlab. Mathematica and Matlab are available to users of the University u-system. Matlab is available on open access computers in several labs, including the information commons area of the main library. Student versions of all three packages are available at CATS for about $125. Students are responsible for getting access to and learning to use a suitable package. Instructions in the appendices to the Trappe-Washington text should be enough to get you started in Mathematica, Maple, or Matlab.

**Attendance:**
Students are expected to attend every
scheduled class, and to be familiar with the University Class Attendance policy
as it appears in the General Catalog.
It is the student's responsibility to keep informed of any
announcements, syllabus adjustments or policy changes made during scheduled
classes

**Grades:**
The total number of points available on
exams and homework is 400.

The point cutoffs for grades will be no higher than those set forth in the following table

360 points (90%) for A

320 points (80%) for B

280 points (70%) for C

240 points (60%) for D

Students withdrawing from the course before March 8 will receive the grade W if they are passing at the time. Students will be considered to be passing at the time of withdraw if they have scored at least 50% on the work completed at that time. The University allows withdraws after March 8, but only with the Dean's signature. Late withdraws will be dealt with on a case by case basis, and requests for late withdraw with a W without a valid reason may or may not be honored.

The grade of I will be awarded if all the following conditions are met:

1. The student has completed all but a small portion of the required work.

2. The student has scored at least 50% on the work completed.

3. The student has a valid reason for not completing the course on time.

4. The student agrees to make up the material in a short period of time.

5. The student asks for the incomplete before grades are due, 48 hours after the final exam.
