| Abstract(in English) | The traveling-salesman cryptosystem is a public key cryptosystem to which the traveling-salesman problem is applied. The well-known traveling-salesman problem is a difficult problem that belongs to the class of NP complete problems. The inventors of this cryptosystem have claimed that this system is safe against the low density attack, because the density associated with this system can be greater tha unity. We will, however, report in this paper that this system can be broken by the Lagarias-Odlyzko attack and its variants, |
