<p>The cryptographic hash function circuit (300) has tables (301, 302, ... 303) and has inputs of ci(j) on the input buses (311, 312,... 313) to the tables (301, 302, ... 303) making outputs on the output buses (321, 322, ... 323) that feed into an exclusive-OR gate (331). The output of the exclusive-OR gate is kj on bus (351). The key K is the concatenation of the eight kj's.</p> |
