TETRIS: Automated Design Space Exploration of Randomness-Latency Trade-offs in Masked Hardware

Given a fixed security order, the randomness and latency of masked hardware present a trade-off. This trade-off has not been structurally examined well enough to enable an efficient search for a user-optimal (randomness/latency-efficient) masked design. Gadget-based masking simplifies masking by replacing each unmasked...

A Survey of Adversarial Efficiency Degradation for Vision Transformer by Exploiting Input-adaptive Optimization

This survey examines a recent class of adversarial efficiency degradation attacks that target these mechanisms to increase computation without necessarily degrading accuracy, and unify and compare two representative attacks across three popular token-pruning frameworks.
