Abstract

A method and system for a multi-user searchable encryption system over ordered keywords is disclosed. The system includes a key generation server which issues a primary key to a user terminal device and a secondary key to a proxy server. A trapdoor is sent by the user terminal and received by the proxy server. The trapdoor is encrypted at the proxy server. The proxy server receives cypher text from the user terminal and sends the cypher text to the database server. A search keyword inputted by the user at the user terminal is used to perform a lookup in encrypted data. REF FIG: 1
