BiShield-TEE: On the (In-)Security of Unilateral Weight Obfuscation in On-Device TEE-Shielded LLM Partition

The paper introduces BiShield-TEE, a bilateral obfuscation framework for on-device large language models that jointly transforms input and output dimensions to create ambiguous solutions, thereby protecting the model from reverse engineering. It identifies a vulnerability in existing unilateral obfuscation methods—called the Solution Determinacy Property (SDP)—which allows attackers to recover the model’s true key and achieve high attack accuracy. Experiments demonstrate that BiShield-TEE limits attack success to the baseline black‑box level while improving inference efficiency on real hardware.
