Associate Professor
Jian Guo is an Associate Professor (with tenure) at Nanyang Technological University (NTU) in Singapore, affiliated with the School of Physical and Mathematical Sciences and holding a courtesy appointment in the College of Computing and Data Science. His research focuses on cryptography, particularly cryptanalysis, design and implementation of symmetric-key algorithms (hash functions, block ciphers, authenticated encryption), and privacy-preserving technologies. PhD in Mathematical Sciences (2007-2010), supervised by Huaxiong Wang, and BEng in Computer Engineering (2003-2006) with First Class Honors from NTU. Jian leads the Cryptanalysis Taskforce at NTU and has published extensively in cryptography. His work includes breaking the full Kravatte PRF design (FSE 2018 Best Paper) and improving related-key boomerang attacks against AES-256 (ACISP 2022 Best Paper). His research also targets cryptographic standards like SHA-3 and AES Hashing, evidenced by a 2021 eprint preimage attack publication. He has received multiple accolades including the NTU/SPMS Young Researcher Award (2021), Collaborative Research Award (2022), and Accelerating Creativity and Excellence Award (2020). He serves on the IACR Board of Directors (2020-present), chairs major conferences (Asiacrypt 2023, Asiacrypt 2021), and contributes to international standardization efforts (ISO/SC27/WG2, Singapore representative since 2017). As a Principal Investigator, he collaborates with industry partners like LatticeX Foundation (2022-2025) and previously PayPal Inc (2021-2023). He actively mentors PhD and postdoc candidates, with ongoing openings jointly advertised at Wuhan University (2025) and Tsinghua University (2024).
