Dr. Gong has been an associate editor of several journals, a co-chair and committee member of technical programs and conferences, and a recipient of awards such as the NSERC Discovery Accelerator Supplement Award and the Ontario Research Fund-Research Excellence Award. Her research interests are in the areas of sequence design, cryptography, and communication security.

"For mathematicians, both students and researchers, the book gives comprehensive information about practical aspects of cryptography. ... Each chapter is supplied with an appropriate number of exercises. They are well chosen to demonstrate and clarify the considered topics. A rich (but not excessively large) bibliography is given at the end of each chapter. This organization of the book is quite handy for the reader." -Nikolai L. Manev, Zentralblatt MATH 1263
