An Efficient Searchable Encryption Scheme using Multi-Indices in Cloud Computing Environments

A Searchable Encryption System enables the clients to search encrypted keywords without compromising the security of the original data. Also, malicious users are able to take advantage of the Searchable Encryption Systems. At the same time, however, they can impose overloads to the system using a Brute force attack. As a result, it could be exposed through retrieving the critical information such as keys and generating huge amount of false queries. Therefore, we propose a novel Searchable Encryption Scheme based on multi-indices by Bloom filter to deal with Brute force attacks efficiently.
