Detailed Description

The ARS4x32, ARS1xm128i, AESNI4x32 and AESNI1xm128i classes export the member functions, typedefs and operator overloads required by a CBRNG class.

ARS1xm128i and AESNI1xm128i are based on the AES block cipher and rely on the AES-NI hardware instructions available on some some new (2011) CPUs.

The ARS1xm128i CBRNG and the use of AES for random number generation are described in Parallel Random Numbers: As Easy as 1, 2, 3 . Although it uses some cryptographic primitives, ARS1xm128i uses a cryptographically weak key schedule and is not suitable for cryptographic use.

Macro Definition Documentation

#define aesni4x32 (   c,
)    aesni4x32_R(aesni4x32_rounds, c, k)

The aesni4x32 macro provides a C API to the AESNI CBRNG, uses the default number of rounds i.e. aesni4x32_rounds

#define ars1xm128i (   c,
)    ars1xm128i_R(ars1xm128i_rounds, c, k)

The ars1mx128i macro provides a C API interface to the ARS CBRNG with the default number of rounds i.e. ars1xm128i_rounds

#define ars4x32 (   c,
)    ars4x32_R(ars4x32_rounds, c, k)

The ars4x32 macro provides a C API interface to the ARS CBRNG with the default number of rounds i.e. ars4x32_rounds
