Shallue said the security of web interactions, such as online purchases, depends on
systems that use large prime numbers. “Some methods for finding large prime numbers
have a small possibility of making mistakes,” Shallue said. “We call these special
numbers pseudoprimes, and I am interested in finding out as much as I can about pseudoprimes.”
He said the research is a result of a trip to the University of Calgary during his
sabbatical in fall 2015 and also through support from an IWU Artistic and Scholarly
Development grant in 2014-15.
“I very much appreciate the support of the University in general, and the Provost’s
Office in particular,” said Shallue.
He earned a Ph.D. from the University of Wisconsin-Madison and joined the faculty
at Illinois Wesleyan in 2009.
