I
have always had a fascination with numbers and patterns
and how they apply in the real world. As a huge Portland
Trailblazers fan, I first came to appreciate math in the
form of basketball statistics. Later, as I advanced in my
school math classes, I came to see how math could be applied
in a wide range of fields, from finance and economics to computer science and engineering. But it was a family vacation that
turned my interest in math into something more and made me
want to do more than study math in a classroom.
The summer before my freshman year, my family and I visited the International Spy Museum in Washington, DC. There,
I learned about the intriguing concept of using mathematical
techniques to communicate securely in the presence of "malicious adversaries"-and I was captivated. I told a math teacher
at my school about my interest, hoping he could guide me in
conducting research in the field. He was unable to teach me the
cryptography and number theory I wanted to learn, but he did
give me a book called A Friendly Introduction to Number Theory
to help me get started.

The following summer, I sent emails to several math
professors working in the field of cryptography at
local colleges and universities, asking if they would
be willing to help me conduct a cryptography research project. At first,
no one was. But I continued to
send emails and make cold
calls until finally, someone
responded.
Dr. Neal Koblitz, a professor at the University of
Washington, is a worldrenowned mathematician
and the inventor of one
of the world's most
secure public-key
cryptographic systems, elliptic curve
cryptography
(ECC). ECC is a
highly sophisticated mathematical
algorithm that uses
algebraic equations
called elliptic curves to encrypt sensitive information. This
algorithm had caught my interest in my initial background
research, so I was astonished when Dr. Koblitz was willing to
meet with me and discuss research ideas.
The first time I visited him in his office at UW that summer,
I was hoping he would provide me with reading material to
expand my knowledge and suggest cool ideas to pursue for a
research project. The meeting went remarkably well: He gave
me a ton of material to read about number theory, including
two books that he wrote himself. Furthermore, he encouraged
me to look into the computational aspects of ECC to see if there
was a way to make them faster. Beginning with that very first
meeting, Dr. Koblitz provided me with two essential things:
direction in what I needed to learn, and answers to my questions whenever I needed them.
In Search of a Problem
For the rest of that summer and most of my sophomore year,
I spent my free time doing research. Not only was it painstaking to learn the number theory behind elliptic curves and
cryptography, but I also had to become proficient at computer
programming, which I accomplished by taking a course at
Portland Community College.
Once I gained the necessary background, I was able to define
a problem for my research: improving the speed of an operation
called scalar multiplication, which refers to multiplying a point
on an elliptic curve by an integer. Scalar multiplication takes up
the majority of running time in cryptographic algorithms, so
it's a critical problem, and one I was excited to work on.
For my research project, I designed, implemented, and
tested new algorithms that were much faster than those
typically used for scalar multiplication. By March 2012, I had
completed a research project I was extremely proud to present
at the regional science fair. All the hard work of learning the
background and doing the actual research had paid off with
successful results, and I had high hopes that I might even make
it to the International Science and Engineering Fair (ISEF).
While I won first place in the math category, I was the only
person competing in that category, and I didn't qualify for ISEF.
Journey into Galois Fields
My disappointment didn't dampen my interest, though. With
Dr. Koblitz's encouragement and suggestions, I delved deeper
into the arithmetic behind ECC algorithms for my next
research project. More specifically, I decided to explore ways
