Survey of Attacks and Defenses against SGX

The great abundance of information brings us convenient life. At the same time, how to prevent malicious attackers from stealing user data or privacy is a hot and difficult issue in the current research of information security. In 2013, Intel proposed a new processor security technology SGX(Software Guard Extensions) at the HASP conference, which can provide a trusted zone named enclave on the computing platform to protect the confidentiality and integrity of user code and data. SGX is a breakthrough research achievement in the field of information security, which is of great significance to individual users and tenants of cloud computing platforms. In order to better study the attacks and defense technologies against SGX, the threat model against SGX attacks is introduced, the types of attacks against SGX are summarized, the defense measures against SGX attacks are analyzed, and the possible future attacks against SGX and the Defense technology was explored.
