Abstract (in Japanese) (See Japanese page) 
(in English) The knapsack cryptosystem invented by Merkle and Hellman is known to be insecure against the low density attack of Lagarias and Odlyzko (LO method)．The Dyck Path cipher (DP cipher) is an alternative to the Merkle-Hellman scheme，which was invented by one of the present authors and was shown to be invulnerable to the LO method. In this report, we present a three dimensional version of the DP cipher (3d-DP cipher). It turned out that the 3d-DP cipher is superior to the DP cipher with respect to the resistivity against the LO attack.
