@defgroup ThreefryNxW Threefry Classes and Typedefs
The ThreefryNxW classes export the member functions, typedefs and
operator overloads required by a @ref CBRNG "CBRNG" class.
As described in
<a href="http://dl.acm.org/citation.cfm?doid=2063405"><i>Parallel Random Numbers: As Easy as 1, 2, 3</i> </a>,
the Threefry family is closely related to the Threefish block cipher from
<a href="http://www.skein-hash.info/"> Skein Hash Function</a>.
Threefry is \b not suitable for cryptographic use.
Threefry uses integer addition, bitwise rotation, xor and permutation of words to randomize its output.
@class r123::Threefry2x32_R
@ingroup ThreefryNxW
exports the member functions, typedefs and operator overloads required by a @ref CBRNG "CBRNG" class.
The template argument, ROUNDS, is the number of times the Threefry round
function will be applied.
As of September 2011, the authors know of no statistical flaws with
ROUNDS=13 or more for Threefry2x32.
@typedef r123::Threefry2x32
@ingroup ThreefryNxW
Threefry2x32 is equivalent to Threefry2x32_R<20>. With 20 rounds,
Threefry2x32 has a considerable safety margin over the minimum number
of rounds with no known statistical flaws, but still has excellent
performance.
@class r123::Threefry2x64_R
@ingroup ThreefryNxW
exports the member functions, typedefs and operator overloads required by a @ref CBRNG "CBRNG" class.
The template argument, ROUNDS, is the number of times the Threefry round
function will be applied.
In November 2011, the authors discovered that 13 rounds of
Threefry2x64 sequenced by strided, interleaved key and counter
increments failed a very long (longer than the default BigCrush
length) WeightDistrub test. At the same time, it was confirmed that
14 rounds passes much longer tests (up to 5x10^12 samples) of a
similar nature. The authors know of no statistical flaws with
ROUNDS=14 or more for Threefry2x64.
@typedef r123::Threefry2x64
@ingroup ThreefryNxW
Threefry2x64 is equivalent to Threefry2x64_R<20>. With 20 rounds,
Threefry2x64 has a considerable safety margin over the minimum number
of rounds with no known statistical flaws, but still has excellent
performance.
@class r123::Threefry4x32_R
@ingroup ThreefryNxW
exports the member functions, typedefs and operator overloads required by a @ref CBRNG "CBRNG" class.
The template argument, ROUNDS, is the number of times the Threefry round
function will be applied.
As of September 2011, the authors know of no statistical flaws with
ROUNDS=12 or more for Threefry4x32.
@typedef r123::Threefry4x32

@class r123::Threefry4x64_R
@ingroup ThreefryNxW
