Cryptanalysis of the MORE symmetric key fully homomorphic encryption scheme
The fully homomorphic symmetric encryption scheme MORE encrypts random keys by conjugation with a random invertible matrix over an RSA modulus. We provide a known-ciphertext cryptanalysis recovering a linear dependence among any pair of encrypted keys.
