Recently, dedicated factoring devices have attracted much attention since it might be a threat for a current RSA-based PKI. In some devices, the clockwise transposition is used as a key technique, however, because of the lack of theoretic proof of the termination, some additional circuits are required. In this paper, we analyze the packet exchanging rule for the clockwise transposition and propose some possible alternatives with keeping the ``farthest-first'' property. Although we have no theoretic proof of the termination, experimental results show actual availability in the clockwise transposition. We also propose an improvement on the routing algorithm for the relation finding step, which establishes two times speed-up. |
