A Proxy Attack-Free Strategy for Practically Improving the Poisoning Efficiency in Backdoor Attacks [PDF]

arXiv, 2023
Poisoning efficiency is crucial in poisoning-based backdoor attacks, as attackers aim to minimize the number of poisoning samples while maximizing attack efficacy. Recent studies have sought to enhance poisoning efficiency by selecting effective samples.

Quasiparticle poisoning effects on the dynamics of topological Josephson junctions [PDF]

Phys. Rev. B 101, 115304 (2020), 2019
The fractional Josephson effect remains one of the decisive hallmarks of topologically protected Majorana zero modes. We analyze the effects of parity violating quasiparticle poisoning onto the current voltage characteristics of topological Josephson junctions.

Boosting Backdoor Attack with A Learnable Poisoning Sample Selection Strategy [PDF]

arXiv, 2023
Data-poisoning based backdoor attacks aim to insert backdoor into models by manipulating training datasets without controlling the training process of the target model. Existing attack methods mainly focus on designing triggers or fusion strategies between triggers and benign samples.
