摘要：For the fully homomorphic encryption schemes in [3, 6], this paper presents attacks to solve an equivalent secret key and directly recover plaintext from ciphertext for lattice dimensions n=2048 with lattice reduction algorithm. Given the average-case behavior of LLL in [8] is true, then their schemes are also not secure for n=8192.
