|
|
|
<p>ISAAC stands for "Indirection, Shift, Accumulate, Add, and Count" which are
|
|
|
the principal bitwise operations employed. It is the most advanced of a
|
|
|
series of array based random number generator designed by Robert Jenkins
|
|
|
in 1996<sup id="fnref1"><a href="#fn1">1</a></sup><sup id="fnref2"><a href="#fn2">2</a></sup>.</p>
|
|
|
<p>ISAAC is notably fast and produces excellent quality random numbers for
|
|
|
non-cryptographic applications.</p>
|
|
|
<p>In spite of being designed with cryptographic security in mind, ISAAC hasn't
|
|
|
been stringently cryptanalyzed and thus cryptographers do not not
|
|
|
consensually trust it to be secure. When looking for a secure RNG, prefer
|
|
|
<a href="../../rand_hc/struct.Hc128Rng.html"><code>Hc128Rng</code></a> instead, which, like ISAAC, is an array-based RNG and one of
|
|
|
the stream-ciphers selected the by eSTREAM contest.</p>
|
|
|
<p>In 2006 an improvement to ISAAC was suggested by Jean-Philippe Aumasson,
|
|
|
named ISAAC+<sup id="fnref3"><a href="#fn3">3</a></sup>. But because the specification is not complete, because
|
|
|
there is no good implementation, and because the suggested bias may not
|
|
|
exist, it is not implemented here.</p>
|
|

<pre><code class="language-text">Input: a, b, c, s[256] // state
|
|
|
Output: r[256] // results
|
|
|
|
|
|
mix(a,i) = a ^ a << 13 if i = 0 mod 4
|
|
|
a ^ a >> 6 if i = 1 mod 4
|
|
|
a ^ a << 2 if i = 2 mod 4
|
|
|
a ^ a >> 16 if i = 3 mod 4
|
|
|
|
|
|
c = c + 1
|
|
|
b = b + c
|
|
|
|
|
|
for i in 0..256 {
|
|
|
x = s_[i]
|
|
|
a = f(a,i) + s[i+128 mod 256]
|
|
|
y = a + b + s[x>>2 mod 256]
|
|
|
s[i] = y
|
|
|
b = x + s[y>>10 mod 256]
|
|
|
r[i] = b
|
|
|
}
|
|
|
</code></pre>
|
|
|
<p>Numbers are generated in blocks of 256. This means the function above only
|
|
|
runs once every 256 times you ask for a next random number. In all other
|
|
|
circumstances the last element of the results array is returned.</p>
|
|
|
<p>ISAAC therefore needs a lot of memory, relative to other non-crypto RNGs.
|
|
|
2 * 256 * 4 = 2 kb to hold the state and results.</p>
|
|
|
<p>This implementation uses <a href="../../rand_core/block/struct.BlockRng.html"><code>BlockRng</code></a> to implement the <a href="../../rand_core/trait.RngCore.html"><code>RngCore</code></a> methods.</p>
