Abstract

Раскрытие направлено на схему непрозрачного шифрования, которая обеспечивает обработку запросов диапазона над зашифрованными числовыми данными, полученными из внешних источников в облаке или на удаленном сервере, и тем самым инкрементное адаптивное индексирование, в результате чего индексируются только те данные, которые запрашиваются доверенными клиентами. В одном варианте осуществления предложен способ индексирования значений данных. Способ содержит этапы, на которых выполняют шифрование множества значений данных с использованием первого режима шифрования для получения зашифрованных значений данных; выполняют шифрование одного или более связанных значений с использованием первого режима шифрования для получения первых зашифрованных связанных значений и с использованием второго режима шифрования для получения вторых зашифрованных связанных значений, причем второй режим шифрования отличается от первого режима шифрования; сравнивают указанное одно или более связанных значений с множеством значений данных с использованием вторых зашифрованных связанных значений и зашифрованных значений данных и индексируют зашифрованные значения данных на основании упомянутого сравнения с использованием первых зашифрованных связанных значений в качестве значений ключа.The disclosure is directed to an opaque encryption scheme that provides processing of range requests over encrypted numeric data received from external sources in the cloud or on a remote server, and thus incremental adaptive indexing, with the result that only data requested by trusted clients is indexed. In one embodiment, a method is provided for indexing data values. The method comprises the steps of encrypting a set of data values using the first encryption mode to obtain encrypted data values; encrypting one or more related values using the first encryption mode to obtain the first encrypted related values and using the second encryption mode to obtain the second encrypted related values, the second encryption mode different from the first encryption mode; comparing said one or more associated values with a plurality of data values using the second encrypted related values and encrypted data values, and indexing the encrypted data values based on the above comparison using the first encrypted related values as key values.
