Highly Evasive Targeted Bit-Trojan (ETBT)

A Bit-Trojan attack framework with high efficacy, evasiveness, and generalizability

ETBT Structure

• Step 1: Key Neuron Extraction (KNE)
  • forward and backward gradient-based method
  • key neuron decoupling
• Step 2: Trigger Generation with Activation Value Suppresstion (TG-AVS)
• Step 3: Constrained Target Bit Search (CTBS)

Code Structure

• adversarialbox/ --adversarial method
• data/ --dataset folder
• data_Model_dependencies/ --pretrained clean model
• models/ --detailed model structure
• ETBT.py --ETBT Complete Process
• KNE_forward_process.py --forward gradient-based process in KNE
• Trigger_generation.py --trigger generation method in TG-AVS

Requirement

• python 3.6.13
• pytorch 1.10.2+cu113
