ePrint Report: Cryptography is Rocket Science: Analysis of BPSec Benjamin Dowling, Britta Hale, Xisen Tian, Bhagya Wimalasiri Space networking has become an increasing area of development with the advent of commercial satellite networks such as those hosted by Starlink and Kuiper, and increased satellite and space presence by governments around the world. Yet, historically such…

ePrint Report: Leveled Functional Bootstrapping via External Product Tree Zhihao Li, Xuan Shen, Xianhui Lu, Ruida Wang, Yuan Zhao, Zhiwei Wang, Benqiang Wei Multi-input and large-precision lookup table (LUT) evaluation pose significant challenges in Fully Homomorphic Encryption (FHE). Currently, two modes are employed to address this issue. One is tree-based functional bootstrapping (TFBS), which uses…

ePrint Report: Efficient Authentication Protocols from the Restricted Syndrome Decoding Problem Thomas Johansson, Mustafa Khairallah, Vu Nguyen In this paper, we introduce an oracle version of the Restricted Syndrome Decoding Problem (RSDP) and propose novel authentication protocols based on the hardness of this problem. They follow the basic structure of the HB-family of authentication protocols…

ePrint Report: ProbeShooter: A New Practical Approach for Probe Aiming Daehyeon Bae, Sujin Park, Minsig Choi, Young-Giu Jung, Changmin Jeong, Heeseok Kim, Seokhie Hong Electromagnetic side-channel analysis is a powerful method for monitoring processor activity and compromising cryptographic systems in air-gapped environments. As analytical methodologies and target devices evolve, the importance of leakage localization and…

ePrint Report: Foundations of Platform-Assisted Auctions Hao Chung, Ke Wu, Elaine Shi Today, many auctions are carried out with the help of intermediary platforms like Google and eBay. These platforms serve as a rendezvous point for the buyers and sellers, and charge a fee for its service. We refer to such auctions as platform-assisted auctions.…

ePrint Report: On the Independence Assumption in Quasi-Cyclic Code-Based Cryptography Maxime Bombar, Nicolas Resch, Emiel Wiedijk Cryptography based on the presumed hardness of decoding codes — i.e., code-based cryptography — has recently seen increased interest due to its plausible security against quantum attackers. Notably, of the four proposals for the NIST post-quantum standardization process that…
