A Ciphertext-Only Attack Against the Cai-Cusick Lattice-Based Public-Key Cryptosystem |
Abstract | ||
|---|---|---|
In 1998, Cai and Cusick proposed a lattice-based public-key cryptosystem based on the similar ideas of the Ajtai-Dwork cryptosystem, but with much less data expansion. However, they didn't give any security proof. In our paper, we present an efficient ciphertext-only attack which runs in polynomial time against the cryptosystem to recover the message, so the Cai-Cusick lattice-based public-key cryptosystem is not secure. |
