A Construction of A New Class of Knapsack-Type Public Key Cryptosystem, K(III)$\Sigma$PKC
Abstract: In this paper, we present a new class of knapsack type PKC referred to as K(III)$\Sigma$PKC.
In a sharp contrast with the conventional knapsack type PKC's, in our proposed scheme, K(III)$\Sigma$PKC, no conventional secret sequence but the natural binary number with noise is used.
We show that the coding rate, a more conservative measure for the security on knapsack PKC, can be made approximately 1.0.
In Appendix, we present K(II)$\Sigma$PKC.
Category / Keywords: public-key cryptography / Public-key cryptosystem(PKC), Knapsack type PKC, Subset-sum problem, LLL algorithm, PQC.
