| Abstract(in English) | The density is a very important parameter in knapsack public-key cryptosystems. It is known that the knapsack cryptosystem is broken with the low-density attack when the density is low. In 2005, Nguyen and Stern introduced the pseudo-density instead of the conventional density in order to evaluate CR and OTU cryptosystems. Recently, Kunihiro introduced a new density in order to unify the conventional density and the pseudo-density. From Kunihiro's result, we can guess that the conventional knapsack PKC is vulnerable to the low-density attack when the weight of the plaintext is low. In this paper, we investigate the relationship between the weight of plaintext and successful attacks in conventional knapsack cryptosystems. |
