Abstract

One of the major limitations of index based encrypted string search on big dataset is the inherent problem of big index generation, maintenance and update which stops it from being dynamic in a sense that one could not modify data or add or remove keywords. Also for a resource constraint client, to generate an index linear in the size of big dataset is difficult. In this paper, we provide an efficient easy-toimplement public key based searchable encryption scheme for string search which is adaptively secure and does not need any index. We provide concrete proof of the adaptive security of our scheme against honest-but-curious server. We validate our scheme against three different publicly available datasets.
