|
|
|
algorithm.</p>
|
|
|
<p>HC-128 is a stream cipher designed by Hongjun Wu<sup id="fnref1"><a href="#fn1">1</a></sup>, that we use as an
|
|
|
RNG. It is selected as one of the "stream ciphers suitable for widespread
|
|
|
adoption" by eSTREAM<sup id="fnref2"><a href="#fn2">2</a></sup>.</p>
|
|
|
<p>HC-128 is an array based RNG. In this it is similar to RC-4 and ISAAC before
|
|
|
it, but those have never been proven cryptographically secure (or have even
|
|
|
been significantly compromised, as in the case of RC-4<sup id="fnref3"><a href="#fn3">3</a></sup>).</p>
|
|
|
<p>Because HC-128 works with simple indexing into a large array and with a few
|
|
|
operations that parallelize well, it has very good performance. The size of
|
|
|
the array it needs, 4kb, can however be a disadvantage.</p>
|
|
|
<p>This implementation is not based on the version of HC-128 submitted to the
|
|
|
eSTREAM contest, but on a later version by the author with a few small
|
|
|
improvements from December 15, 2009<sup id="fnref4"><a href="#fn4">4</a></sup>.</p>
|
|
|
<p>HC-128 has no known weaknesses that are easier to exploit than doing a
|
|
|
brute-force search of 2<sup>128</sup>. A very comprehensive analysis of the
|
|
|
current state of known attacks / weaknesses of HC-128 is given in <em>Some
|
|
|
Results On Analysis And Implementation Of HC-128 Stream Cipher</em><sup id="fnref5"><a href="#fn5">5</a></sup>.</p>
|
|
|
<p>The average cycle length is expected to be
|
|
|
2<sup>1024*32+10-1</sup> = 2<sup>32777</sup>.
|
|
|
We support seeding with a 256-bit array, which matches the 128-bit key
|
|
|
concatenated with a 128-bit IV from the stream cipher.</p>
|
|
|
<p>This implementation uses an output buffer of sixteen <code>u32</code> words, and 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>
