Abstract(in English) | The present author previously proposed a new scheme of strengthening a wide class of PKC's, referred to as K(I)Scheme. In this paper, we present a new class of knapsack type PKC referred to as K(I)ΣPKC, based on K(I)Scheme. In a sharp contrast with the conventional knapsack type PKC's, in our proposed scheme, K(I)ΣPKC, no secret sequence is used. As a result, the set of public keys can be made sufficiently random. We also show that the coding rate, a more conservative measure for the security of knapsack PKC, can be made sufficiently large. The K(I)ΣPKC would be secure against any linear transformation attack including LLL attack. |
