Intel® Secure Key

The processor supports Intel® Secure Key (formerly known as Digital Random Number Generator or DRNG), a software visible random number generation mechanism supported by a high-quality entropy source. This capability is available to programmers through the RDRAND instruction. The resultant random number generation capability is designed to comply with existing industry standards in this regard (ANSI X9.82 and NIST SP 800-90).

Some possible usages of the RDRAND instruction include cryptographic key generation as used in a variety of applications, including communication, digital signatures, secure storage, etc.

RDRAND specifications and functional descriptions are included in the Intel® 64 Architectures Software Developer’s Manual, Volume 2. Available at:
