SgxSpectre Attack Can Extract Data from Intel SGX Enclaves
A new variation of the Spectre attack has been revealed this week by six scientists from the Ohio State University. Named SgxSpectre, researchers say this attack can extract information from Intel SGX enclaves. Intel Software Guard eXtensions (SGX) is a feature of modern Intel processors that allow an application to create so-called enclaves.
This enclave is a hardware-isolated section of the CPU’s processing memory where applications can run operations that deal with extremely sensitive details, such as encryption keys, passwords, user data, and more.
