Low Weight Discrete Logarithms and Subset Sum in 20.65n with Polynomial Memory
Low weight dlog subset sum representations Nested Rho

We propose two polynomial memory collision finding algorithms for the low Hamming weight discrete logarithm problem in any abelian group GG. The first one is a direct adaptation of the Becker-Coron-Jo...
Improved Low-Memory Subset Sum and LPN Algorithms via Multiple Collisions

Iterative collision search procedures play a key role in developing combinatorial algorithms for the subset sum and learning parity with noise (LPN) problems. In both scenarios, the single-list pair-w...

We construct a public-key encryption (PKE) scheme whose
security is polynomial-time equivalent to the hardness of the Subset Sum
problem. Our scheme achieves the standard notion of indistinguishabil...

SHipher: Families of Block Ciphers based on SubSet-Sum Problem
Block cipher SubSet-Sum problem Framework
font style='font-size:12px;'>
2016/1/25
In this paper, we describe the families of block ciphers named SHipher. We
show a symmetric encryption framework based on the SubSet-Sum problem.
This framework can provide families of secure, flexi...
