Course Announcement

In Spring 2015, Professor Jason Howell will offer a special topics course called “Introduction to Cryptography” (MATH 480/580). Here is his description of the course:

AliceBobCryptography is the study of techniques for secure communication of information in the presence of third parties who are regarded as adversaries.  Most methods for encrypting information are highly mathematical in nature, and the security of many cryptosystems depends on the computational difficulty of problems in number theory and finite fields.  In this course we provide a basic introduction to cryptography and discuss classical cryptosystems that have been employed over the last 2000 years.  We then  develop the mathematical background necessary to describe several modern cryptosystems in use today, including the public-key Diffie-Hellman system and the RSA algorithm, and discuss the security and vulnerability of these methods to attacks.

In order to enroll in the course, students must have completed

  • MATH 207 (Discrete Structures) or MATH 295 (Introduction to Abstract Mathematics); and
  • MATH 203 or an equivalent Linear Algebra course

Students seeking to enroll without these prerequisites are asked to contact Prof. Howell. The course will meet on Tuesday and Thursday evenings from 7-8:15PM.

Mathematical Explorations Seminar Series

Next week, the College of Charleston Math Club and the Department of Mathematics will host a seminar talk designed for undergraduate students. We hope to offer more talks of this kind in the future. The talk is open to the public and no particular mathematical background is required.

From the logic of a thief to a painless proof
of Gödel’s Incompleteness Theorem

by Professor Renling Jin, College of Charleston’s Department of Mathematics

Date, time, and location: Wednesday October 15th 2014, 3-4pm in Maybank Hall Room 117

Abstract: In the talk we will present some puzzles and paradoxes to demonstrate the importance of formalism and mathematical logic in our everyday life. These will lead to one of the most important theorems in the twentieth century’s mathematics: Gödel’s Incompleteness Theorem. All related concepts will be explained and a short and very elementary explanation of the proof of the theorem will be presented.
