A BIOS file is a copy of the operating system used by the hardware that a Core is emulating. Some Cores need BIOS files in order to correctly emulate hardware and/or software as needed by the content. RetroArch and LibRetro do not share any copyrighted system files or game content. You ...
SGX is vulnerable to side-channel attacks. Although Intel has released security advisories to fix several security breaches in the past, the ÆPIC leak vulnerability, which affects many Intel Core and Xeon Ice Lake processors, has yet to be patched. Plus, it’s still possible for malware...
Bootloader.Once the hardware is initialized, the BIOS searches for a bootable device based on the boot order specified in its settings. This could be ahard drive,SSD, CD/DVD drive, orUSBdevice. The BIOS then loads a small program called the bootloader from the selected device into memory. ...
Support for the use of SGX is present in Ubuntu 21.04 whilst hardware support for this feature has been present in various Intel processors on the desktop in recent years and the upcoming Xeon “Ice Lake” processors will provide SGX for server platforms as well. Userspace Security Improvements...
Such an environment provides a safe space for secrets when other parts of the infrastructure are compromised. This includesBIOS,firmware, root access, virtual machine manager, etc. When an application is protected with Intel SGX, its operation and integrity are unaffected in case of an attack. ...
So, if sophisticated malware, for example, attacks the OS, BIOS, VMM, or SMM layers, Intel SGX is there to offer an additional layer of protection via placement of your sensitive data within an isolated, encrypted portion of memory. So, these layers can be compromised, but your data is ...
I try namely sgx_enable_device or sgx_create_enclave. Both calls hang for cca 20 - 30 seconds and then the process that calls them is killed by OS and boot continues. The hang happens after every hard-reboot with one exception - when I disable and enable SGX in ...

There are, however, some instances where it would be better to not encrypt a portion of memory, so Intel TME allows the BIOS to specify a physical address range to remain unencrypted. TME can be enabled or disabled by IT admins in the BIOS settings. The AES-XTS mode, which is usually...
