Verified NTT Multiplications for NISTPQC KEM Lattice Finalists: Kyber, SABER, and NTRU
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Postquantum cryptography requires a different set of arithmetic routines from traditional public-key cryptography such as elliptic curves. In particular, in each of the lattice-based NISTPQC Key Establishment finalists, every state-ofthe-art optimized ...

Optimizing BIKE for the Intel Haswell and ARM Cortex-M4
Transactions on Cryptographic Hardware and Embedded Systems, 2021 BIKE is a key encapsulation mechanism that entered the third round of the NIST post-quantum cryptography standardization process. This paper presents two constant-time implementations for BIKE, one tailored for the Intel Haswell and one tailored for the ...

Concurrency and Computation: Practice and Experience, Volume 35, Issue 28, 25 December 2023., 2023 Summary In this article, we explore the usage of scalable vector extension (SVE) to vectorize number‐theoretic transforms (NTTs). In particular, we show that 64‐bit modular arithmetic operations, including modular multiplication, can be efficiently implemented with SVE instructions.

Diagonally‐Addressed Matrix Nicknack: How to improve SpMV performance
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 4, December 2023., 2023 Abstract We suggest a technique to reduce the storage size of sparse matrices at no loss of information. We call this technique Diagonally‐Addressed (DA) storage. It exploits the typically low matrix bandwidth of matrices arising in applications. For memory‐bound algorithms, this traffic reduction has direct benefits for both uni‐precision and multi ...

Software Optimization for Fast Encoding and Decoding of Reed-Solomon Codes
Telfor Journal, 2022 In this work, we propose a software library written in C for encoding and decoding Reed-Solomon codes. Library consists of one scalar codec and two vectorized codecs for x86 architecture.

Transcoding unicode characters with AVX‐512 instructions
Software: Practice and Experience, Volume 53, Issue 12, Page 2430-2462, December 2023., 2023 Abstract Intel includes in its recent processors a powerful set of instructions capable of processing 512‐bit registers with a single instruction (AVX‐512). Some of these instructions have no equivalent in earlier instruction sets. We leverage these instructions to efficiently transcode strings between the most common formats: UTF‐8 and UTF‐16.

Performance characterization of video analytics workloads in heterogeneous edge infrastructures
Concurrency and Computation: Practice and Experience, Volume 35, Issue 14, 25 June 2023., 2023 Summary Powered by deep learning, video analytic applications process millions of camera feeds in real‐time to extract meaningful information from their surroundings. And this number grows by the minute. To avoid saturating the backhaul network and provide lower latencies, a distributed and heterogeneous edge cloud is postulated as a key enabler for ...

Oil and Vinegar: Modern Parameters and Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Two multivariate digital signature schemes, Rainbow and GeMSS, made it into the third round of the NIST PQC competition. However, neither made its way to being a standard due to devastating attacks (in one case by Beullens, the other by Tao, Petzoldt ...

Editing Compressed High‐resolution Voxel Scenes with Attributes
Computer Graphics Forum, Volume 42, Issue 2, Page 235-243, May 2023., 2023 Abstract Sparse Voxel Directed Acyclic Graphs (SVDAGs) are an efficient solution for storing high‐resolution voxel geometry. Recently, algorithms for the interactive modification of SVDAGs have been proposed that maintain the compressed geometric representation. Nevertheless, voxel attributes, such as colours, require an uncompressed storage, which can

Implicit propagation of directly addressed grids in lattice Boltzmann methods
Concurrency and Computation: Practice and Experience, Volume 35, Issue 8, 10 April 2023., 2023 Summary Lattice Boltzmann methods (LBM) are well suited to highly parallel computational fluid dynamics simulations due to their separability into a perfectly parallel collision step and a propagation step that only communicates within a local neighborhood.
