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)$\Sigma$PKC, based on K(I)Scheme.
In a sharp contrast with the conventional knapsack type PKC's, in our proposed scheme, K(I)$\Sigma$PKC, 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)$\Sigma$PKC would be secure against any linear transformation attack including LLL attack. |
