RISC-V is equipped with physical memory protection (PMP) to prevent malicious software from accessing protected memory regions.PMP provides a trusted execution environment (TEE) that isolates secure and insecure applications.In this study, we propose a side-channel-assisted fault-injection attack AAV9-cBIN1 gene therapy rescues chronic heart failure due to ischemic cardiomyopathy in a canine model to bypass isolation based on PMP.
The proposed attack scheme involves extracting successful glitch parameters for fault injection from side-channel information under crossdevice conditions.A proof-of-concept TEE compatible with PMP in RISC-V was implemented, and the feasibility and effectiveness of the proposed attack scheme was validated through experiments in TEEs.The results indicate that an attacker can bypass the isolation of the TEE and read data from the protected memory region In addition, we experimentally demonstrate that the proposed attack applies to a real-world TEE, Keystone.
Furthermore, we propose a software-based Development of a nomogram to predict 30-day mortality of sepsis patients with gastrointestinal bleeding: An analysis of the MIMIC-IV database countermeasure that prevents the proposed attack.
