Batch Fully Homomorphic Encryption over the Integers


We extend the fully homomorphic encryption scheme over the integers of van Dijk et al. (DGHV) into a batch fully homomorphic encryption scheme, i.e. to a scheme that supports encrypting and homomorphically processing a vector of plaintexts as a single ciphertext. We present two variants in which the semantic security is based on different assumptions. The… (More)
