“Mathematics and Cryptology”

• In this cyber age, cryptology plays the vital role of maintaining the confidentiality, integrity and authenticity of all kinds of information in all aspects of our lives, such as online shopping, credit cards, passwords, cryptocurrencies or even national security.
• The main objectives of this year’s competition are to introduce the students to the exciting field of cryptology and to let the students explore the mathematical aspects of cryptology and its applications.
• We also hope that through this competition, students can grasp the idea of inter-disciplinary research, as research in today’s cryptology involves mathematics, computer science, electrical engineering, communication science and physics.
