A Randomized Response Protocol Based on Homomorphic Encryption
Kun Mei Cao, Ke Li · Advanced materials research · 2014
The investigation which involves the respondents privacy is hard to ensure the information security. To rectify this problem, Based on Homomorphic Response Protocol (RRPBH), a novel protocol using homomorphic encrypted system is proposed in this paper. The RRPBH uses the Paillier encryption algorithm to encrypt respondents answer. Paillier algorithm has the good properties of additive homomorphism and mixed multiplicative homomorphism. We can effectively compute the sum of respondents answer with better privacy protection by this protocol.
