RDRAND
Sign in to saveAlso known as RDSEED
RDRAND (for "read random") is an instruction for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source. It is also known as Intel Secure Key Technology, codenamed Bull Mountain. Intel introduced the feature around 2012, and AMD added support for the instruction in June 2015. RDRAND is available in Ivy Bridge processors and is part of the Intel 64 and IA-32 instruction set architectures.

RDRAND (for "read random") is an instruction for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source. It is also known as Intel Secure Key Technology, codenamed Bull Mountain. Intel introduced the feature around 2012, and AMD added support for the instruction in June 2015. RDRAND is available in Ivy Bridge processors and is part of the Intel 64 and IA-32 instruction set architectures.
The random number generator is compliant with security and cryptographic standards such as NIST SP 800-90A, FIPS 140-2, and ANSI X9.82. After a request from Intel, Cryptography Research Inc. released research on RDRAND in the paper ''Analysis of Intel's Ivy Bridge Digital Random Number Generator.
