Teaching Enigma.

Codes. Ciphers. Encryption. Krysztof Gaj has made it his life’s work to engage the complex world of cryptography.

Kris Gaj received the MSc And PhD in Electrical Engineering from Warsaw University of Technology. As the founder of a technology company in his native country of Poland, he generated cryptographic software applications for Polish financial institutions. In 1998, he joined the faculty at Mason, where his current research projects center on new hardware structures for secret-key ciphers, hash functions, public-key cryptosystems, and factoring benchmarking of cryptographic hardware. In addition, he works to develop specialized libraries and application kernels for high-performance reconfigurable computers. Gaj also wrote a book on the World War II use of the German Enigma machine and the techniques used to break Hitler’s code; a historical point in the advancement of code technology.

Gaj leads students to greater understanding and acuity in advanced engineering and encryption in a variety of senior and graduate courses. Beyond the classroom, Gaj interacts with numerous international professional and academic communities in the field.
