Improving GGH Public Key Scheme Using Low Density Lattice Codes
Channel Coding Code-Based Cryptography Lattice Codes
2016/1/3
Goldreich-Goldwasser-Halevi (GGH) public key cryptosystem is an instance of lattice-based cryptosystems whose security is based on the hardness of lattice problems. In fact, GGH cryptosystem is the la...
Low-Density Attack Revisited
subset sum problem knapsack-based cryptosystem low-density attack lattice problem
2008/9/12
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
all the problems of ...
