Jun-Peng Chen received his master's and doctoral degrees from the Department of Electrical Engineering and Graduate Institute of Communication Engineering, National Taiwan University. Since 2014, he has dedicated his research to side-channel analysis and hardware security. Transactions on Cryptographic Hardware and Embedded Systems (TCHES) is the top journal of the International Association for Cryptographic Research (IACR) in this research field. Prof. Chen’s Side-Channel Analysis of Post-quantum cryptography on the ARM Cortex-M4 processor has two papers on TCHES, which are currently the only two papers in this research area in Taiwan.
The content of this speech includes an introduction to the ASCON algorithm, our research team’s hardware implementation results, and its Side-Channel Analysis (SCA). The National Institute of Standards and Technology (NIST) announced in 2023 that the ASCON series of algorithms is a Lightweight Cryptography standard for Internet of Things (IoT) devices. ASCON boasts a simple structure compared to the Advanced Encryption Standard (AES) and Hash functions like SHA-256, which have been used for over 20 years. This design architecture can simultaneously meet the Symmetric-key Algorithm and Hash function requirements. However, whether in software or hardware implementation, ASCON remains vulnerable to attacks from Side-Channel Analysis, and attackers may even utilize Machine Learning or Deep Learning technologies to enhance attack efficiency.
