Abstract

We analyze the possibility of implementation of cloud computing over private data that is based on previously proposed threshold fully homomorphic cryptosystems. The main result is a protocol for securer cloud computing over private data in a model with supplementary cryptoservers. As a result, one gets a system that does not require a public key and replaces a sophisticated and costly bootstrapping by a more efficient reencryption protocol run by the cryptoservers.
