Overview

RSA Security Inc. and Intel Corporation have teamed to provide C programmers access to the Intel Random Number Generator via the RSA BSAFE® Crypto-C interface.

Intel Hardware Security Features

The Intel® hardware security features are intended to provide a hardware infrastructure for cryptographic functions, such as random number generation. Version 1.0 of the hardware security features includes the Intel Random Number Generator (RNG), dedicated hardware that harnesses system thermal noise to generate random and indeterministic values. The generator is free-running, accumulating random bits of data until a 32-bit buffer is filled.

RSA BSAFE Crypto-C Interface

The RSA BSAFE Crypto-C software includes the RSA BSAFE Hardware API (BHAPI) interface, which allows manufacturers to provide an interface between their hardware and Crypto-C. Programmers who wish to take advantage of the hardware capabilities of a specific manufacturer, such as those provided by Intel, can simply incorporate
