Report title:High security public key encryption: ciphertext purification and steganography
Personal introduction: Huang Xinyi，Researcher at Hong Kong University of Science and Technology (Guangzhou)，Has been engaged in public key cryptography research，Host the National Natural Science Foundation of China’s outstanding youth projects and key projects，The research work won the first prize of the Cryptozoological Innovation Award of the Chinese Cryptozoological Society，First Prize of seabet casino review Ministry of Education Natural Science Award、Second Prize, etc.；Serves as a director of the China Cryptozoology Society，"Chinese Science: Information Science"、Editorial Board Member of "Journal of Cryptozoology"，Member of the Asian Esoteric Association Steering Committee、Member of Program Committee (2020-2023) etc.
Abstract:In a strong confrontation environment，The assumption of key confidentiality is no longer valid。Aiming at seabet casino review covert key theft attack，Introducing purifying encryption，Rerandom by ciphertext，Eliminate the key information carried in the ciphertext。Forced escrow for keys，Introducing steganographic encryption，By ciphertext ambiguity，Achieve confidential communication。
