Intel® Secure Key, previously code-named Bull Mountain Technology, is the Intel name for the Intel® 64 and IA-32 Architectures instruction RDRAND and its underlying Digital Random Number Generator (DRNG) hardware implementation. Among other things, the DRNG using the RDRAND instruction is useful for generating high-quality keys for cryptographic protocols.
This Digital Random Number Generator Software Implementation Guide is intended to provide a complete source of technical information on RDRAND usage, including code examples. Included in this document are the following additional sections:
Section 2: Random Number Generator (RNG) Basics and Introduction to the DRNG. This section describes the nature of an RNG and its pseudo- (PRNG) and true- (TRNG) implementation variants, including modern cascade construction RNGs. We then present the DRNG's position within this broader taxonomy.
Section 3: DRNG Overview. In this section, we provide a technical overview of the DRNG, including its component architecture, robustness features, manner of access, performance, and power requirements.
Section 4: RDRAND Instruction Usage. This section provides reference information on the RDRAND instruction and code examples showing its use. This includes RDRAND platform ...
