&lt;p&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;is a special-purpose iterated block cipher, targeted at certain applications with heavily constrained resources and very low traffic of encrypted messages. A typical scenario is the synchronization of tokens, an infrequent operation involving the exchange of just a few encrypted bytes under a fixed or seldom updated key. &lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;1&quot;&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;1&quot;&gt;Saci &lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;is an instance of the Wide Trail family of algorithms which includes the AES cipher, and displays both &lt;/font&gt;&lt;/font&gt;&lt;i&gt;&lt;font face=&quot;Arial,Arial&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;Arial,Arial&quot; size=&quot;2&quot;&gt;involutional structure&lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;, in the sense that the encryption and decryption modes differ only in the key schedule, and &lt;/font&gt;&lt;/font&gt;&lt;i&gt;&lt;font face=&quot;Arial,Arial&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;Arial,Arial&quot; size=&quot;2&quot;&gt;cyclic key schedule&lt;/font&gt;&lt;/font&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;&lt;font face=&quot;Helvetica-Normal,Helvetica-Normal&quot; size=&quot;2&quot;&gt;, whereby the round subkeys can be computed in-place in any order.&lt;/font&gt;&lt;/font&gt; &lt;/i&gt;&lt;/i&gt;
