    Refined TFHE Leveled Homomorphic Evaluation and Its Application

    No full text
    TFHE is a fully homomorphic encryption scheme over the torus that supports fast bootstrapping. Its primary evaluation mechanism is based on gate bootstrapping and programmable bootstrapping (PBS), which computes functions while simultaneously refreshing noise. PBS-based evaluation is user-friendly and efficient for small circuits; however, the number of bootstrapping operations increases exponentially with the circuit depth. To address the challenge of efficiently evaluating large-scale circuits, Chillotti et al. introduced a leveled homomorphic evaluation (LHE) mode at Asiacrypt 2017. This mode decouples circuit evaluation from bootstrapping, resulting in a speedup of hundreds of times over PBS-based methods. However, the remaining circuit bootstrapping (CBS) becomes a performance bottleneck, even though its frequency is linear with the circuit depth. In this paper, we refine the LHEmodebymitigatingthe highcost of CBS. First, we patch the NTT-based CBS algorithm proposed by Wang et al. [WWL+, Eurocrypt 2024], accelerating their algorithm by up to 2.6×. Then, observing the suboptimal parallelism and high complexity of modular reduction in NTT under CBS parameters, we extend WWL+ to an FFT-based algorithm by redesigning the pre-processing method and introducing a split FFT technique. This achieves the fastest CBS implementation with the smallest key size, outperforming the open-source WWL+ implementation by up to 12.1× (resp. 5.12× compared to our patched algorithm), and surpassing TFHEpp [MBM+,USENIX2021]by3.42×withakeysize reduction of 33.2×. Furthermore, we proposed an improved integer input LHE mode byextending our CBS algorithm to support higher precision and combining it with additional optimizations such as multi-bit extraction. Compared to the previous integer input LHE mode proposed by Bergerat et al. [BBB+, JoC 2023], our approach is up to 10.7× faster with a key size reduction of up to 4.4×. To demonstrate the practicality of our improved LHE mode, we apply it to AES transciphering and general homomorphic look-up table (LUT) evaluation. For AES evaluation, our method is 4.8× faster and reduces the key size by 31.3× compared to the stateof-the-art method, Thunderbird [WLW+, TCHES 2024]. For LUT evaluation, we compare our results with the recent work of Trama et al. [TCBS, ePrint 2024/1201], which constructs a general 8-bit processor of TFHE. Our method not only achieves faster 8-to-8 LUTevaluation but also improves the efficiency of most heavy 8-bit bivariate instructions by up to 21× and the 16-bit sigmoid function by more than 26×

    A Study of the Classical Landscape at the Wang River Villa of Wang Wei

    No full text
    The landscape of Wang Wei's Wang River Villa is examined by reviewing the essays and papers written about the poetical collaboration, the “Wang River Collection.” The purpose of this paper is to clarify the meaning of villa architecture in China. The author expects that this research will contribute to a mutual understanding between cultures. The villa was a Utopia for Wang. On the other hand, he was a pious Buddhist and Buddhistic concepts are reflected in the landscape. I consider the features of the classical landscape of Xie Lingyun and "Chu Ci," as written in “The Collection,” a reflection of the Buddhistic concept. When considering what the classics meant to Wang Wei, it is apparent that his villa is a representation of the classical landscape. It is not an imitation of the classical landscape, but a unique and original creation of art by Wang.departmental bulletin pape

    Supporting the research process through expanded library data services

    No full text
    Purpose – The purpose of this paper is to describe how the authors gained a better understanding of the variety of library users' data needs, and how gradually some new data services were established based on current capabilities.Design/methodology/approach – This paper uses a case study of the new data services at the John Cotton Dana Library, at Rutgers, The State University of New Jersey, Newark campus, to demonstrate the possible ways to extend data reference services and provide data computing services. A content analysis of services records shows how each user group falls into the multiple data services levels and subcategories.Findings – Library users can be classified into many different categories, and each of these may have different needs. Research centers might have big projects involving data gathering and applications where a librarian can mainly provide consultation; while an individual faculty member or student might need the librarians as research partners, with help for their specific problems. Computing data services can involve group training and statistical analysis assistance, where researchers need emergent help. Data librarians can take various opportunities for data management education, thereby gradually raising awareness and cultivating better research habits among researchers.Originality/value – Library data computing services can make unique contributions to faculty and students' research and study. Institution, library and users' interaction determines the levels and extent of data services and is generalized from the description and analysis of typical data service examples. Classic concept of data services levels is applied to a concrete case of data services program, and sub-categories of each data services level and user types are developed based on the authors' services record.This article is (c) Emerald Group Publishing and permission has been granted for this version to appear here at the RUcore: Rutgers University Community Repository .
