Detailed Description

The Intel® SGX SDK now provides interfaces that facilitate custom alignment of secrets and structures containing secrets. The Intel® Software Guard Extensions SDK for Linux* (Intel® SGX SDK for Linux*), version 2.7.101, and Intel® Software Guard Extensions SDK for Windows* (Intel® SGX SDK for Windows*), version 2.5.101, are the first versions with this support. There are different interfaces for secrets that are statically-defined (stack, global, static) versus dynamically-defined (heap) and for secrets in C++ code versus C code.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
