Exploiting Per-Core Leakage: Electromagnetic Side-Channel Monitoring of Multicore Architectures
Daehyeon Bae, Sujin Park, Insup Lee +4
Multicore processors are increasingly adopted in embedded systems to meet growing performance demands. However, physical side-channel analysis of multicore architectures remains un…
Optimizing Polynomial Multiplication and Fixed-Weight Sampling for HQC on ARM Cortex-M4
Jihoon Jang, Hanbeom Shin, Suhri Kim +2
In this paper, we present an optimized implementation of Hamming Quasi-Cyclic (HQC) on the ARM Cortex-M4. We optimize (i) the polynomial multiplication and (ii) the support expansi…
MIFA: An MILP-based Framework for Improving Differential Fault Attacks
Hanbeom Shin, Insung Kim, Sunyeop Kim +6
At ASIACRYPT 2021, Baksi et al. introduced DEFAULT, a block cipher designed to algorithmically resist Differential Fault Attack (DFA), claiming 64-bit DFA security regardless of th…
New Space-Efficient Quantum Algorithm for Binary Elliptic Curves using the Optimized Division Algorithm
Hyeonhak Kim, Seokhie Hong
In previous research, quantum resources were concretely estimated for solving Elliptic Curve Discrete Logarithm Problem(ECDLP). In [1], the quantum algorithm was optimized for the…
