Abstract As a diversion we return in this chapter to another (once) promising public-key encryption scheme using a trap-door function:Knapsack encryption. It, too, is based on residue arithmetic, but uses multiplication rather than exponentiation, making it easier to instrument and theoretically mor...

Computer Science - Cryptography and SecurityIn this paper, we analyze a knapsack schemes. The one is suggested by Su, which is relied on a new method entitled permutation combination method. We demonstrate that this permutation method is useless to the security of the scheme. Since the special ...
In general, the modular knapsack problem can be solved using a lattice reduction algorithm, when its density is low. The complexity of lattice reduction algorithms to solve those problems is upper-bounded in the function of the lattice dimension and the maximum norm of the input basis. In the...
For instance, in the domain of cryptography [19], a knapsack problem variant was explored for encryption and security applications. In logistics [22], strategies inspired by the knapsack problem are employed to optimize cargo and supply chain management. Similarly, in multimedia [14], knapsack-ins...

Our construction is a precoding-based encryption algorithm and uses the knapsack problem to perform a permutation and pad some random fogged data to the message bits. Compared to other approaches were introduced today, our approach is very simple and more efficient....
In this paper we break a knapsack based two-lock cryptosystem proposed at ICICS03 [7]. The two-lock cryptosystem is a commutative encryption algorithm that is very useful for the construction of the general t-out-of-n oblivious transfers and millionaire protocol. However, our analysis shows ...
