Improving the Privacy of Tor Onion Services, by Edward Eaton and Sajin Sasy and Ian Goldberg
Onion services enable bidirectional anonymity for parties that communicate over the Tor network, thus providing improved privacy properties compared to...
Counting Vampires: From Univariate Sumcheck to Updatable ZK-SNARK, by Helger Lipmaa and Janno Siim and Michal Zajac
We propose a univariate sumcheck argument $mathfrak{Count}$ of essentially optimal communication efficiency of one group element. While the previously most...
Benchmarking and Analysing the NIST PQC Finalist Lattice-Based Signature Schemes on the ARM Cortex M7, by James Howe and Bas Westerbaan
This paper presents benchmarking and profiling of the two lattice-based signature scheme finalists, Dilithium and Falcon, on the ARM Cortex...
Constant Latency in Sleepy Consensus, by Atsuki Momose and Ling Ren
Dynamic participation support is an important feature of Bitcoin's longest-chain protocol and its variants. But these protocols suffer from long...
A New Feistel Approach Meets Fluid-SPN: Griffin for Zero-Knowledge Applications, by Lorenzo Grassi and Yonglin Hao and Christian Rechberger and Markus Schofnegger and Roman Walch and Qingju Wang
Zero-knowledge (ZK) applications form a large group of use cases in modern cryptography, and recently gained in popularity due to...
Improved Rotational-XOR Cryptanalysis of Simon-like Block Ciphers , by Jinyu Lu and Yunwen Liu and Tomer Ashur and Bing Sun and Chao Li
Rotational-XOR (RX) cryptanalysis is a cryptanalytic method aimed at finding distinguishable statistical properties in ARX-C ciphers, i.e., ciphers that can...
ZKAttest: Ring and Group Signatures for Existing ECDSA Keys, by Armando Faz-Hernández and Watson Ladd and Deepak Maram
Cryptographic keys are increasingly stored in dedicated hardware or behind software interfaces. Doing so limits access, such as permitting only...
A toolbox for verifiable tally-hiding e-voting systems, by Véronique Cortier and Pierrick Gaudry and Quentin Yang
In most verifiable electronic voting schemes, one key step is the tally phase, where the election result is computed from...
SPDZ2k: Efficient MPC mod 2^k for Dishonest Majority, by Ronald Cramer and Ivan Damgård and Daniel Escudero and Peter Scholl and Chaoping Xing
Most multi-party computation protocols allow secure computation of arithmetic circuits over a finite field, such as the integers modulo a...
