<p>The <a class="el" href="struct_l_u_c.html">LUC</a> function. </p>
<p>This class is here for historical and pedagogical interest. It has no practical advantages over other trapdoor functions and probably shouldn't be used in production software. The discrete log based <a class="el" href="struct_l_u_c.html">LUC</a> schemes defined later in this .h file may be of more practical interest. </p>
