Title: A Quasi-polynomial time Quantum Algorithm for the Extrapolated Dihedral Coset Problem.      FLYER

Abstract: The Learning With Errors (LWE) problem, introduced by Regev (STOC’05), is one of the fundamental problems in lattice-based cryptography, believed to be hard even for quantum adversaries. Regev (FOCS’02) showed that LWE reduces to the quantum Dihedral Coset Problem (DCP) and later, Brakerski et al. (PKC 2018) extended this to the more general Extrapolated Dihedral Coset Problem (EDCP). In this talk, we present a quasi-polynomial time quantum algorithm for solving EDCP over power-of-two moduli, using a quasi-polynomial number of samples. We stress that our algorithm does not affect the security of LWE with standard parameters, as the reduction from standard LWE to EDCP limits the number of samples to be polynomial. 

Bio: Hansraj is a PhD student in the Department of Mathematics and Statistics at Florida Atlantic University, Boca Raton. Prior to starting his doctoral studies, he worked as a Junior Research Fellow at the Defense Research and Development Organization (DRDO), Delhi. His research interests include lattice based cryptography and quantum algorithms.

Title:  Invariant Circles of the Standard Map

Abstract:   Our goal with the following study is to lead to finding quasiperiodic orbits of the Circular Restricted Three Body Problem. A flow has quasiperiodic behavior if the associated Poincare map has quasiperiodic behavior. This encourages us to first look first at maps, and in this case, we look at a very well-known map, the standard map. An orbit exhibits Quasiperiodic behavior in a map if it is topologically conjugate to a rigid rotation of an irrational

number. As given in the systematic recipe by Dr. Mireles James and David Blessing, we first compute the rotation number of the quasiperiodic orbit using the weighted Birkhoff averaging method. Then we use a Newton scheme to solve a conjugacy equation describing the circle resulting in the Fourier expansion of the quasiperiodic invariant circle. Finally, we observe the error of this method on multiple initial conditions.

Title:  Novel Representations of log 2 Through Polynomial Continued Fractions      FLYER

Abstract:   This presentation explores new representations of the mathematical constant log 2 using polynomial continued fractions. Building on previous work in continued fraction theory, we investigate a conjecture by Zhu He which proposes a specific polynomial continued fraction for log 2. We will demonstrate the validity of this conjecture and introduce an infinite family of new polynomial continued fractions for log 2.

Speaker: Alibek Orynbassar, Senior Lecturer, Department of Pedagogy of Natural Sciences, SDU University  

Title:  Complete Classification of Quadratic Irrationals with Period Two    FLYER

Abstract: This talk presents a full classification of quadratic irrationals whose continued fraction expansions have period length two. While it is known that the continued fraction of  N  is periodic, the distribution of period lengths is less understood. We establish precise conditions for the period-two case and illustrate the results with numerical examples.

Title: FOLEAGE: F4OLE-Based Multi-Party Computation for Boolean Circuits       FLYER

Abstract:  Secure Multi-party Computation (MPC) allows two or more parties to compute any public function over their privately-held inputs, without revealing any information beyond the result of the computation. Modern protocols for MPC generate a large amount of input-independent preprocessing material called multiplication triples, in an offline phase. This preprocessing can later be used by the parties to efficiently instantiate an input-dependent online phase computing the function. 

To date, the state-of-the-art secure multi-party computation protocols in the preprocessing model are tailored to secure computation of arithmetic circuits over large fields and require little communication in the preprocessing phase, typically O(N · m) to generate m triples among N parties. In contrast, when it comes to computing preprocessing for computations that are naturally represented as Boolean circuits, the state-of-the-art techniques have not evolved since the 1980s, and in particular, require every pair of parties to execute a large number of oblivious transfers before interacting to convert them to N-party triples, which induces an Ω(N^2 · m) communication overhead.

In this paper, we introduce FOLEAGE, which addresses this gap by introducing an efficient preprocessing protocol tailored to Boolean circuits. FOLEAGE exhibits excellent performance: It generates m multiplication triples over F2 using only N · m + O(N^2 · log m) bits of communication for N-parties, and can concretely produce over 12 million triples per second in the 2-party setting on one core of a commodity machine. Our result builds upon an efficient Pseudorandom Correlation Generator (PCG) for multiplication triples over the field F4. Roughly speaking, a PCG enables parties to stretch a short seed into a large number of pseudorandom correlations non-interactively, which greatly improves the efficiency of the offline phase in MPC protocols. Our construction significantly outperforms the state-of-the-art, which we demonstrate via a prototype implementation. This is achieved by introducing a number of protocol-level, algorithmic-level, and implementation-level optimizations on the recent PCG construction of Bombar et al. (Crypto 2023) from the Quasi-Abelian Syndrome Decoding assumption.

Speaker:  Anil Kumar Pradhan, Founding Cryptographer and Cryptography Research Lead, Vaultree

Title: Beyond Theory: Industry Challenges in Adopting Homomorphic Encryption

Abstract: Fully Homomorphic Encryption (FHE) promises quantum-resilient, privacy-preserving computation for sensitive data across industries. However, despite academic breakthroughs, the leap from laboratory models to enterprise-scale adoption remains daunting. Industry faces formidable obstacles, including computational resource demands, implementation complexity, slow processing speeds, and high costs, aggravated by a shortage of FHE talent and lack of standardized practices. Integrating FHE into legacy and cloud systems requires extensive technical overhaul, often with questionable ROI. The disconnect between academic solutions and practical business needs, especially regarding scalability, cost, and integration continues to deter widespread implementation. Emerging technologies and optimization strategies, such as hardware acceleration and real-world application benchmarking, may help bridge the gap, but genuine adoption will require collaborative efforts and a shift in focus from theoretical promise to operational feasibility. Bio

Title:  LastRings: Lattice-based Scalable Threshold Ring Signatures    FLYER

Abstract:  This talk presents the first lattice-based threshold ring signature scheme with signature size scaling logarithmically in the size of the ring while supporting arbitrary thresholds. Our construction is also concretely efficient, achieving signature sizes of less than 150kB for ring sizes up to N=4096 (with threshold size T=N/2, say). This is substantially more compact than previous work.

Our approach is inspired by the recent work of Aardal et al. (CRYPTO 2024) on the compact aggregation of Falcon signatures, that uses the LaBRADOR lattice-based SNARKs to combine a collection of Falcon signatures into a single succinct argument of knowledge of those signatures. We proceed in a similar way to obtain compact threshold ring signatures from Falcon, but crucially require that the proof system be zero-knowledge in order to ensure the privacy of signers. Since LaBRADOR is not a zkSNARK, we associate it with a separate (non-succinct) lattice-based zero-knowledge proof system to achieve our desired properties.

57th Southeastern International Conference on Combinatorics, Graph Theory, and Computing

Celebrating its 57th year, the Conference brings together mathematicians and others interested in combinatorics, graph theory and computing, and their interactions. The Conference lectures and contributed papers, as well as the opportunities for informal conversations, have proven to be of great interest to other scientists and analysts employing these mathematical sciences in their professional work in business, industry, and government.

The Conference continues to promote better understanding of the roles of modern applied mathematics, combinatorics, and computer science to acquaint the investigator in each of these areas with the various techniques and algorithms which are available to assist in his or her research. Each discipline has contributed greatly to the others, and the purpose of the Conference is to decrease even further the gaps between the fields.
