Dr. Ron Mullin

Distinguished Emeritus Professor, University of Waterloo 

Co-founder, Certicom 

A humble, dedicated professor and mathematician who is modest about his successes, Dr. Ron Mullin has made invaluable contributions to combinatorics, academia and cryptography. His career has spanned over 50 years with notable successes in both commercial and academic ventures. Along with Scott Vanstone and Gord Agnew, Ron Mullin co-founded Certicom, a leading cryptography company whose technology was licensed by the US National Security Agency (NSA), among many others, and later sold to Research In Motion (RIM), now known as  BlackBerry. Mullin was also Professor and Chair of Combinatorics and Optimization at the University of Waterloo and boasts one of the largest lineages in the Mathematics Genealogy project, with 20 PhD students and 180 descendants. 

“Teaching as a whole and getting good students and working with them, it’s a wonderful thing,” said Mullin. 

Even as a student, Mullin’s impact was profound. He was the first ever University of Waterloo graduate to receive an MA in mathematics in 1960. A bright and promising young mathematician and cryptology student, Mullin was recruited by the University of Waterloo to lecture while he completed his graduate studies. His skills were so impressive that the University’s head of mathematics used Mullin as bait to lure world class mathematician, who later was acknowledged as the World War II codebreaker and cryptography expert, William Tutte to the university with the intention of building out the department and recruiting top-tier talent. 

“It was quite an honour,” Mullin reflected, when asked about his role in attracting Tutte to the university. 

After completing his PhD under Tutte, Mullin went on to pursue a career as a professor at the University of Waterloo until 1996, rising the ranks from lecturer to distinguished professor emeritus and adjunct professor. Described by two of his former students as brilliant, encouraging and easy going, Mullin always left a lasting impression on those he taught, as well as his colleagues. 

“Ron taught my first computer science class,” said Alfred Menezes, one of Mullin’s academic grandchildren and professor in the Department of Combinatorics and Optimization at the University of Waterloo. “To him, the little details didn’t matter. He thinks about the big stuff – the important stuff…he realized the value of ideas.” 

One of those ideas became the foundation for Mullin’s commercial venture – Certicom, a leading supplier of wireless security solutions. Mullin was heavily involved in the company’s patent program. Certicom’s signature product was Elliptic Curve Cryptography, which speeds up the encryption process, utilizing shorter encryption keys without loss of security. This technology played a crucial role in the advancement of smartphone and other mobile devices and accelerated the growth of a number of companies including RIM. 

“One good thing about it – it’s fast and secure for certain kinds of encryption processes. And these turned out to be the ones that are very helpful in smartphones,” said Hugh Williams, retired computer science professor and Mullin’s academic son. “So in a sense, Scott, Gord and Ron realized this was a coming thing and they were quite skillful in introducing this company.”

After retiring from the University of Waterloo as a Distinguished Professor Emeritus and stepping away from his commercial ventures, Mullin went on to enjoy a second career at Florida Atlantic University in Boca Raton. He established a Cryptography Group at the university, a position he held until his “second retirement”, at the age of 75. Mullin also became the first recipient of the Stanton Medal, which is awarded by the Institute for Combinatorics and its Applications to honour significant lifetime contributions promoting the discipline of combinatorics through advocacy, outreach, service, teaching and/or mentoring. In addition, Mullin was awarded a doctor rerum naturalium honoris causa (Honorary Doctorate Degree) from the University of Rostock in Germany. 

While Mullin’s professional accomplishments are impressive, his legacy cannot be fully understood without including his mathematics genealogy. A number of graduate students that studied under Mullin became very prominent in cryptography and computer science including: Hugh Williams, who was instrumental in establishing one of Canada’s leading research centres in cryptography and information security; Scott Vanstone, world-renowned cryptography and co-founder of Certicom; Douglas Wiedemann, who designed an algorithm for linear systems of equations before joining the NSA; Bimal Roy, head of R C Bose Centre for Cryptology and Security in India; and Evi Nemeth, engineer, author and teacher who played a prominent role in the development of the Unix computer operating system.  

“He has had many students and ultimately, for an academic, that’s your impact – your students. What they end up doing and how they add to what it was that you did,” said Williams.
