Recommender systems are an integral part of online platforms that recommend new content to users with similar interests. However, they demand a considerable amount of user activity data….
Constructive Side-Channel Analysis and Secure Design. COSADE 2024, (Gardanne, Aix-Marseille, France), 2024
This work investigates using Homomorphic Encryption (HE) to assist the security evaluation of cryptographic devices without revealing side-channel information. For the first time….
“Preview Writeup”: In anticipation of a package submission to the NIST Threshold Call, 2026
his preview writeup represents a plan to submit Schmivitz to the NIST Threshold Call. Schmivitz is a Vector Oblivious Linear Evaluation in the Head (VOLEitH) Zero-Knowledge (ZK) system that includes two gadgets, Weak VOLEs and VOLEitH, which can be used as building blocks for cryptographic applications such as threshold signature and encryption schemes….
