Design of Lightweight Linear Diffusion Layers from Near-MDS Matrices

2017 · DOAJ (DOAJ: Directory of Open Access Journals)

Near-MDS matrices provide better trade-offs between security and efficiency compared to constructions based on MDS matrices, which are favored for hardwareoriented designs. We present new designs of lightweight linear diffusion layers by constructing lightweight near-MDS …

Constructing Low-latency Involutory MDS Matrices with Lightweight Circuits

2019 · Lirias

MDS matrices are important building blocks providing diffusion functionality for the design of many symmetric-key primitives. In recent years, continuous efforts are made on the construction of MDS matrices with small area footprints in the …

ECDSA White-Box Implementations: Attacks and Designs from CHES 2021 Challenge

2022 · IACR Transactions on Cryptographic Hardware and Embedded Systems

Despite the growing demand for software implementations of ECDSA secure against attackers with full control of the execution environment, scientific literature on ECDSA white-box design is scarce. The CHES 2021 WhibOx contest was thus held …
