Propomos um protocolo para converter a função de criptografia de um texto cifrado em outra função de criptografia, mantendo a mensagem correspondente em segredo. O protocolo proposto permite conversões dos criptossistemas El Gamal e Paillier e tem potencial para projetar um protocolo multipartidário eficiente destinado a circuitos que consistem em operações aritméticas e lógicas. Esclarecemos a condição dos circuitos de forma que o protocolo multipartidário baseado no protocolo proposto forneça melhor desempenho do que as abordagens anteriores. Além disso, apresentamos alguns cálculos estatísticos que preservam a privacidade como uma aplicação eficaz do protocolo proposto.

Abstract: We propose a protocol for converting the encryption function of a ciphertext into another encryption function while keeping the corresponding message secret. The proposed protocol allows conversions of the El Gamal and Paillier cryptosystems and has the potential to design an efficient multiparty protocol intended for circuits consisting of arithmetic and logical operations. We clarify the condition of circuits such that the multiparty protocol based on the proposed protocol provides better performance than previous approaches. In addition, we introduce some privacy-preserving statistical computations as an effective application of the proposed protocol.
