Microarchitectural side-channel attacks pose a significant threat to mixed-criticality embedded systems by exploiting shared hardware resources to induce information leakage and timing interference. This work presents a lightweight, deterministic run-time detection architecture integrated into a hypervisor environment....

DantinoX is presented, an open-source JAX/Flax library in which a single modular Transformer backbone serves all three paradigms, which enables controlled cross-paradigm comparisons within one API for training, streaming inference, and benchmarking.

This work shows that, despite disrupting the spatial structure required by conventional reconstruction attacks, transmitted token embeddings retain substantial positional information, and introduces the Spatially Aligned Reconstruction Attack (SARA), a unified pipeline that predicts token positions, restores their spat...
Experiments on ImageNet across multiple ViT architectures and attacks show that decoys can redirect high attention scores away from the true adversarial region while preserving much of the attack effectiveness, revealing a fundamental limitation of using attention magnitude as an indicator of adversarial relevance.
