Abstract
This paper presents an attack on the fully homomorphic encryption over the integers by using lattice reduction algorithm. Our result shows that the FHE in [4] is not secure for some parameter settings. We also present an improvement FHE scheme to avoid this lattice attack. Keywords: Fully Homomorphic Encryption, Cryptanalysis, Lattice Reduction
