This is a PyThorh implementation of Backdoor Attack on Link Prediction via Node Injection, as described in our paper:

Haibin Zheng, Haiyang Xiong, Haonan Ma, Guohan Huang, Jinyin Chen, Link-Backdoor: Backdoor Attack on Link Prediction via Node Injection

The code requires Python >=3.6 and is built on PyTorch. Note that PyTorch may need to be installed manually depending on different platforms and CUDA drivers.

We provide the datasets used in our paper:

[ "cora","cora_ML" ,"citeseer","pubmed","CS"]

Find the links for attack training

python find_link.py --model VGAE --dataset_str cora --hidden1 32 \
--hidden2 16 --dropout 0.1 --lr 0.01

Training the link_backdoor model

python main.py --model VGAE --dataset_str cora --hidden1 32 \
--hidden2 16 --dropout 0.1 --lr 0.01 --attalink 540 --alllink 876
