Abstract

encriptação homomórfica com aplicações para recuperação de informações privadas. uma solicitação é recebida para informações específicas que podem ser determinadas usando dados em um banco de dados em um primeiro sistema de computador. pelo menos alguns dos dados estão criptografados ou a solicitação está criptografada. o primeiro sistema de computador não possui uma chave de descriptografia para descriptografar os dados criptografados ou solicitação. o primeiro sistema de computador executa operações de he compactáveis nos dados para determinar o(s) texto s) cifrado(s) compactado(s) que correspondem às informações específicas. as operações incluem o uso de um primeiro esquema he não compactado e um segundo esquema he compactado. o primeiro esquema he é usado nos dados para criar outros textos cifrados múltiplos e o segundo esquema he é usado nos outros textos cifrados múltiplos para empacotar os outros textos cifrados múltiplos em menos textos cifrados que são compactados. ambos os esquemas he usam a mesma chave secreta. o primeiro sistema de computador envia uma resposta incluindo texto(s) cifrado(s) compactado(s) correspondente(s) à informação específica.
