On the subset sum problem over finite fields
Abstract. The subset sum problem over finite fields is a well known NPcomplete problem. It arises naturally from decoding generalized Reed-Solomon codes. In this paper, we study th...

Branching proofs of infeasibility in low density subset sum problems
We prove that the subset sum problem ax = x {0, 1}n (SUB) has a polynomial time computable certificate of infeasibility for all a with density at most 1/(2n), and for almost all ...

Solving Medium-Density Subset Sum Problems in Expected Polynomial Time
The subset sum problem (SSP) (given n numbers and a target bound B, find a subset of the numbers summing to B), is one of the classical NP-hard problems. The hardness of SSP vari...

Public-Key Cryptographic Primitives Provably as Secure as Subset Sum
Abstract. We propose a semantically-secure public-key encryption scheme whose security is polynomialtime equivalent to the hardness of solving random instances of the subset sum pr...

Low-density attack revisited
The low-density attack proposed by Lagarias and Odlyzko is a powerful algorithm against the subset sum problem. The improvement algorithm due to Coster et al. would solve almost a...
