ACKNOWLEDGMENTS
Firstly, I would like to sincerely thank my supervisor, Prof. Dr. Vu Van Yem,
who not only provided direct scientific guidance but also supported me in all
aspects during my PhD studies at Hanoi University of Science and Technology. It
would have been very challenging for me to complete my research without his
tolerance, inspiration, support, and extensive expertise.
Hereby, I would like to thank the School of Electrical and Electronic
Engineering, Hanoi University of Science and Technology, Academy of
Cryptography Techniques created favorable conditions for me during my PhD
studies. My appreciation goes to the Vietnam Government Information Security
Commission for allowing me to participate in the internship program at the Japan
Advanced Institute of Science and Technology (JAIST).
Next, I would also like to express my gratitude to the Master, PhD
Scholarship Programme of Vingroup Innovation Foundation, the Taiwanese
Businessmen's Study Promotion Association in Vietnam, for granting me a
scholarship that allows me to pursue a graduate program at Hanoi University of
Science and Technology.
