Abstract

Una solicitud es recibida para información específica que se puede determinar utilizando datos en una base de datos en un primer sistema informático. Al menos algunos de los datos son cifrados o la solicitud está cifrada. El primer sistema informático no tiene una clave de cifrado para cifrar los datos o la solicitud cifrados. El primer sistema informático lleva a caobo operaciones HE comprimibles en los datos para determinar el texto cifrado comprimido que corresponde a la información específica. Las operaciones incluyen utilizar un primer esquema HE no comprimido y un segundo esquema HE comprimido. El primer esquema HE se utiliza en los datos para crear otros textos cifrados múltiples y el segundo esquema HE se utiliza en los otros textos cifrados múltiples para empaquetar los otros textos cifrados múltiples en pocos textos cifrados comprimidos. Ambos de los esquemas HE utilizan una misma clave secreta. El primer sistema informático envía una respuesta que incluye textos cifrados que corresponde a la información específica.
