Galois/Counter Mode (GCM) serves as a mandatory or default authenticated encryption mode in widely deployed security protocols, including TLS 1.3, IPsec, MACsec (IEEE 802.1AE), SSH, WPA3, and QUIC, which makes implementation-level vulnerabilities in GCM a concern of broad practical significance. In this study, we revis...

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 expansion in fixed-weight sampling, and (iii) propose an optional caching strategy that reuses the public transforms and hash recomputed under a fi...

Multicore processors are increasingly adopted in embedded systems to meet growing performance demands. However, physical side-channel analysis of multicore architectures remains underexplored, as obtaining usable leakage is inherently challenging. Consequently, side-channel security research on such systems has lagged...
