Paillier´s encryption: Implementation and cloud applications

Paillier´s additive homomorphic encryption is increasingly used in recent research in the field of cloud secure outsourcing and privacy-preserving computation in addition to other cryptographic tools such as garbled circuits. In this paper, we review Paillier´s encryption and its application to privacy-preserving computation outsourcing and secure online voting. We present a new implementation of Paillier´s cryptosystem using Python as for interface language and fast GMP C-routines for arithmetic operations.
