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.
