چکیده

Merkle and Hellman proposed a first knapsack cryptosystem. However, it was broken because the density is not sufficiently high. In this paper, we propose a a new trapdoor in modular knapsack PKC. Proposed scheme can use the message encoding. This method can use the method of enlarging messages over a finite field in order to realize a high density over 1. Keywords— Knapsack public-key cryptosystem, Knapsack problem, Modular multiplication, Trapdoor.

Knapsack Public-Key Cryptosystem Using Chinese Remainder Theorem

The realization of the quantum computer will enable to break publickey cryptosystems based on factoring problem and discrete logarithm problem. It is considered that even the quantum computer can not solve NP -hard problem in a polynomial time. The subset sum problem is known to be NP -hard. Merkle and Hellman proposed a knapsack cryptosystem using the subset sum problem. However, it was broken...

Cryptanalytic attacks on the multiplicative knapsack cryptosystem and on Shamir's fast signature scheme

The basic Merkle-Hellman additive trapdoor knapsack public-key cryptosystem was recently shown to be insecure, and attacks have also been developed on stronger variants of it, such as the Graham-Shamir system and the iterated knapsack cryptosystem. This paper shows that some simple variants of another Merkle-Hellman system, the multiplicative knapsack cryptosystem, are insecure. It is also show...

Analysis of Digital Knapsack Based Sealed Bid Auction

The need of totally secure online auction has led to the invention of many auction protocols. But as new attacks are developed, auction protocols also require corresponding strengthening. We analyze the auction protocol based on the well-known mathematical public-key knapsack problem for the design of asymmetric public-key knapsack trapdoor cryptosystem. Even though the knapsack system is not c...

Tractable Rational Map Signature

Digital signature schemes are crucial for applications in electronic commerce. The effectiveness and security of a digital signature scheme rely on its underlying public key cryptosystem. Trapdoor functions are central to public key cryptosystems. However, the modular exponentiation for RSA or the discrete logarithms for ElGamal/DSA/ECC, as the choice of the trapdoor functions, are relatively s...

QTRU: quaternionic version of the NTRU public-key cryptosystems

In this paper we will construct a lattice-based public-key cryptosystem using non-commutative quaternion algebra, and since its lattice does not fully fit within Circular and Convolutional Modular Lattice (CCML), we prove it is arguably more secure than the existing lattice-based cryptosystems such as NTRU. As in NTRU, the proposed public-key cryptosystem relies for its inherent securi...
