Cryptography Discussion Participation**

* The term
paper will be a short paper (4 pages)
describing a person or cryptographic method pertaining to cryptology. I
will
give you a handout later this semester showing possible topics. I must
approve
the topic you choose. The paper should be typewritten (using Microsoft
Word,
for example) using 1.5 line spacing and should have good grammatical
structure
with references clearly stated. Do not plagiarize! The term paper will
be due
on Thursday November 30^{th}.

** For
this part of the grade, you will be required to
participate in Desire2Learn
(D2L)
discussion groups. This discussion will include you
communicating with your classmates in groups (preferably using the
wireless
capabilities of your laptop) in a secret manner using some of the
cryptographic
techniques we study in class. You will have the opportunity to encrypt
and
decrypt your own messages and to break messages sent by others.

membership or permission of instructor.

**“Makeup”
Test Policy**: Approval for
making up a missed test should be given
__prior__
to the scheduled test. The makeup test must be taken
within __one__
__week__
following the scheduled test. Documentation is required for
all
make-ups. Except for extraordinary circumstances, approval for a makeup
test
will not be granted if the scheduled test has already been given.

**Late
Homework Policy: **Late hand
written homework will be accepted but only
limited credit will be given. I consider late homework to be homework
turned in
later than 5:00 p.m. of the day the assignment is due. The maximum
number of
points a student can receive for a late homework is ten points lower
than the
minimum grade of all students who have turned in the assignment on
time. For
example, if an assigned homework is worth 80 points and the lowest
score of the
on-time assignments is 60/80, the maximum grade a student can receive
for the
assignment is 50/80. __No__
__exceptions__
to this policy will
be granted
except for extreme circumstances that require official university
documentation
or a predetermined arrangement between the student and myself that is
done __prior__
to the assignment due date. Late assignments must be turned in within __one__
__class__
__day__
of the assignment due date to obtain any
credit.

**Attendance
Policy**:
Attendance __is__
a requirement in this class. If you miss a
class, you are responsible for making up any missed work. Attendance
will be
taken each class period. Attendance means **RESPONSIBILITY
**– I look much more
favorably on students who have good
attendance habits.

**Laptop/Cell
Phone/Electronic Device Policy:**
No
cell phones, computers, or other
electronic devices are
to be used in this class when these devices are not being used in a way
that is
conducive for learning what is being taught in class during a
particular day or
time. Determining what is conducive will be left up to the instructor's
discretion. The instructor retains the right to ask a student to leave
class if
they exhibit this or any __other__
__behavior__
that is a
distraction to
learning for other students in the class.

**Catalog
Course
Description:**
An
introduction to the application of mathematical ideas for Honors
students.
Topics vary. This course can be taken more than once with different
topics.
This course has been approved for credit in the Mathematical Sciences
of the
Core Curriculum.

**Student
Goals and Objectives of the Course: **Students
should gain a deeper understanding and appreciation for mathematics and
its
applications, and some skill in addressing the particular types of
quantitative
issues included in the course.**
**Math
132 concentrates on applications. Applications likely to be
treated—cryptology
is an example—are those which are interesting to many people,
can
be profitably
approached using only elementary mathematics, and reward careful study
with
deepened understanding and appreciation of the power and beauty of
mathematics.

Students
will be able
to use the tools of mathematics and quantitative reasoning to
conceptualize and
solve problems. Students will be able to:

a.
identify and
interpret relationships among numeric, symbolic, and graphical
information

b. generate mathematical models using numeric, symbolic, and graphical
information for use in

real-world applications

c. solve problems using numeric, symbolic, and graphical information.

**Disability
Policy:** Students seeking academic accommodations under the
Americans with Disabilities Act must register with the Center for Accessibility
Services (CAS) to determine eligibility. Students qualified for academic accommodations
will receive accommodation letters and should meet with each course professor
during office hours, to review and discuss accommodations. To begin the
registration process, complete a Student Registration Form and submit
documentation to PO Box 6902, Radford, Virginia 24142, or deliver to the
Russell Hall, Room 325, by fax to 540-831-6525, or by
email to cas@radford.edu (See
documentation guidelines). For more information, visit the Center for
Accessibility Services (CAS) website or call 540-831-6350.

**Honor
Code:**
By accepting
admission to Radford University, each student makes a commitment to
understand,
support, and abide by the University Honor Code without compromise or
exception. Violations of the University Honor Code include (but are not
limited
to): lying, stealing and unauthorized possession of property, cheating,
multiple submission, and plagiarism. This class will be conducted in
strict
observation of the honor code. Refer to your Student Handbook for a
