MaTEE to defend against SGVs. MaTEE utilizes Arm Pointer Authentication (PA) to bind each request to the corresponding CA's identity and then verifies the identity when the CA accesses sensitive data, thereby preventing malicious request forgery. In particular, MaTEE isolates sensitive data of different CAs without modifying existing CAs and TAs. Our evaluation demonstrates that MaTEE successfully defends against SGVs with a minimal runtime overhead (2.19%).">
