<p></p> <p><b>New page</b></p><div>According to NIST's [http://csrc.nist.gov/groups/ST/hash/documents/FR_Notice_Nov07.pdf FR call] (section 4.A), it seems that Brandon Enright's partial collisions &lt;i&gt;do&lt;/i&gt; break Spectral Hash. The relevant text is this:<br /> <br /> &quot;NIST expects the SHA–3 algorithm of message digest size &lt;i&gt;n&lt;/i&gt; to meet the following security requirements at a minimum. [...] any result that shows that the candidate algorithm does not meet these requirements will be considered to be a serious attack. [...] Any &lt;i&gt;m&lt;/i&gt;-bit hash function specified by taking a fixed subset of the candidate function's output bits is expected to meet the above requirements with &lt;i&gt;m&lt;/i&gt; replacing &lt;i&gt;n&lt;/i&gt;.&quot;<br /> <br /> Should Spectral Hash be labeled broken, then?<br /> <br /> Paulo.</div>
