  Program:  The Mathematics of Cryptography:  From Caesar to RSA

  Speaker:  Dr. Joseph Kirtland, Marist College

  About the topic:

  The art of sending coded messages dates back thousands of 
years.  After a brief discussion of the history of cryptography 
through World War II, this talk will focus on the mathematics 
necessary for modern cryptography.  More specifically, this talk 
will trace the development of public key cryptography with an 
emphasis on the RSA public key cryptosystem.   With computing 
power increasing at a seemingly exponential rate, the talk will 
end with a brief discussion of what could be next for public key 

  About the Speaker

  Dr. Kirtland is a professor of mathematics at Marist College, 
where he has taught since 1992.  He received his B.S. from 
Syracuse University and his Ph.D. from the University of New 
Hampshire.  His professional interests are in finite group theory 
(an area from abstract algebra), mathematics education, and the 
applications of group theory to cryptography and check digit 

  Professionally, Dr. Kirtland has written numerous articles on a 
variety of research topics in finite group theory. Additionally, 
Dr. Kirtland studies the application of group theory to the 
creation and use of check digit schemes.  Based on his efforts, 
he wrote a book, entitled Identification Numbers and Check Digit 
Schemes, published by the Mathematical Association of America 
(MAA).  One reviewer wrote:  "This is a superb book on many 
levels. . . . Truly one of the best demonstrations of the utility 
of mathematics that exists today."  

  On a personal note, Dr. Kirtland enjoys running, hiking, 
basketball, poetry, and playing fantasy baseball.
