A Random Ensemble of Encrypted Vision Transformers for Adversarially Robust Defense

Ryota Iijima, Sayaka Shiota, Hitoshi Kiya

Deep neural networks (DNNs) are well known to be vulnerable to adversarial examples (AEs). In previous studies, the use of models encrypted with a secret key was demonstrated to be…

Efficient Fine-Tuning with Domain Adaptation for Privacy-Preserving Vision Transformer

Teru Nagamori, Sayaka Shiota, Hitoshi Kiya

We propose a novel method for privacy-preserving deep neural networks (DNNs) with the Vision Transformer (ViT). The method allows us not only to train models and test with visually…

A Random Ensemble of Encrypted models for Enhancing Robustness against Adversarial Examples

Ryota Iijima, Sayaka Shiota, Hitoshi Kiya

Deep neural networks (DNNs) are well known to be vulnerable to adversarial examples (AEs). In addition, AEs have adversarial transferability, which means AEs generated for a source…
