The team of Lanzhou University Information College participated in the World Black Hat Conference (BLACK HAT USA 2022) and made it

The World Black Hat Conference Black Hat USA 2022 was held online and offline in Las Vegas from August 6th to 11th. This year's BLACK HAT USA has 101 issues from well -known security research institutions such as GoogleProject Zero, German Heimhoz Information Security Center, 360 Vulnerability Research Institute, and 101 issues from well -known universities such as Harvard University, the University of California, Northwestern University, and Purdue University. The Network Space Security Research Team of the Ministry of Engineering Research Center of Lanzhou University and the Real -time System Education Research Center has become the only Chinese university team in Mainland China, a Chinese university team that has been selected as the conference and sharing results sharing reports. This study was completed by Liu Xin, a 2019 doctoral student at the School of Information, and Tan Yuan, a 2019 undergraduate student. This is also the second time the team successfully selected the Blackhat series conference after successfully selected Blackhat ASIA 2021.

The sound clone based on artificial intelligence technology is a new type of attack method in recent years, and it is a hot issue in the field of content security. At present, a large number of studies have been tried to detect them. Most of these testing methods have reported very outstanding detection effects (accuracy rates exceeded 98%). In this study, the team conducted an in-depth analysis of the characteristic engineering methods of the existing testing scheme, creatively proposed the concept of "the speaker's irrelevant characteristics" and designed a new sound clone attack framework SIF-Deepvc based on this. The extensive real world verification has proved that SIF-Deepvc can effectively break through the existing sound cloning detection method and change the offensive and defensive situation in this field to a certain extent. In the future, the research team will further explore the new type of offensive and defensive confrontation technology of sound cloning.

Open source software and real -time system education research center's network space security research team has long been engaged in information security offensive and related technical research. In the past five years, the team has made a series of progress in the field of blockchain, code analysis, and traffic detection. It has won a second prize of scientific and technological progress in Gansu Province. In the IJIM, TDSC, ESEM and other well -known journals and conferences, SCI/EI indexing indexes There are more than 20 papers, and one of the papers is selected into ESI.

Background Information:

The Black Hat conference is recognized as the highest event in the world information security industry and is also the most technical information security conference. It is held once a year in the United States, Europe, and Asia. The conference focused on the latest network security incidents, technological research and development trends, and attracted the participation of security practitioners from all over the world with its strong technical, cutting -edge and authority. Among them, BLACK HAT USA has a history of 25 years, the most large -scale and authoritative, and is known as "hacker Oscar".
