November 16, 2021: Dr. Khuat Van Thanh (Le Quy Don Tech. Univ.), Laser Fault Injection in a 32-bit Microcontroller: From the Flash Interface to the Execution Pipeline

Fault Injection (FI) is an active side-channel attack in which an attacker induces faults to the target and further exploits them to extract secret information by differential analysis (fault vs no-fault). Many FI techniques have been developed, such as clock or voltage tampering, Electromagnetic fault injection, Laser fault injection (LFI). The attacks can be classified into invasive, semi-invasive, and noninvasive attacks. LFI can be classified into semi-invasive techniques because the device needs to be unpackaged to guarantee that the light can reach the circuit layer. In this attack technique, a laser source is used to induce ionization in electronic circuit devices, causing the targets to behave differently. LFI has an extremely high spatial resolution which makes it possible to achieve a local effect on a single element with even the most advanced technology. This talk is about a method for obtaining faults using Laser Fault Injection (LFI) in a 32-bit Microcontroller (MCU) from the Flash interface to the execution pipeline via the AHB bus.

Van Thanh Khuat received a Bachelor’s degree at Xidian University, China in 2012. As a student, he was awarded several times the “excellent student” scholarship for international students. In the year of 2011, he took part in the national contest of electronics circuit design for students and won the second prize in the Shannxi province. In 2012, he got a full scholarship from CSC scholarships for his Ph.D. program. In 2016, he achieved a Ph.D. degree from Xi’an Jiaotong University, China, and his Ph.D. thesis was graded excellent. He is currently a lecturer at the Department of Information security, Le Quy Don Technical University. From 2020 to 2021, he held a postdoc position at Telecom Paris, France. His research interests include embedded security and fault injection. He also has co-authored several publications at top journals and conferences in the fields.

February 2, 2024: Dr. Khoa D. Doan (Vin Univeristy) Toward Reliable and Practical Machine Learning Applications

While Machine Learning (ML) has rapidly transformed several domains and applications with incredible successes, there are also important areas where the progress is significantly slower. Specifically, there exists a widened complexity gap between the methods currently investigated in research and those used in practice in these areas. One reason is that many algorithms, despite achieving […]

February 2, 2024: Prof. Heng Ji (University of Illinois at Urbana-Champaign), Combating with Misinformation and Cancer: A Unified Multimodal AI Approach to Healthy and Happy Life

A research overview of ongoing research projects, especially focusing on two that are most related to the VinUni-UIUC Smart Health Center: (1) Misinformation Detection and Trustworthy Large Language Models; (2) Joint Natural Language and Molecule Learning for Drug Discovery. Unsurprisingly these two seemingly different research problems can be tackled with a unified approach based on […]

January 11, 2024: Dr. Le Duc Trong (FIT-UET) Resilient Multimodal Learning for Multimodal Emotion Recognition in the Presence of Incomplete Modalities

Multimodal Emotion Recognition in Conversation (Multimodal ERC) is a critical area of research for interpreting human communication in diverse applications. Nevertheless, the persistent issue of uncertain missing modalities poses a major hurdle, hampering the development of robust Multimodal ERC models. Existing approaches face limitations in effectively leveraging a fusion of diverse data modalities encompassing audio, […]
