Comparative study on RSA algorithm of multi-keyword search scheme over encrypted cloud data

Cloud computing offers advantages in terms of scalability and availability as the ability to access resources anytime and anywhere over an external server can bring about issues concerning data privacy, however. To combat this, one might have the data go through an encryption process prior to a server upload. This approach however can tamper with the ability to work with the data on a plain text level. Hence, it is necessary to enable the cloud server to make use an encrypted search feature for efficient data accessibility. This paper intends to provide a comparative study of keyword search-based of multi-keyword ranked search implementations with the intention of comparing them in terms of efficiency. The performance of these implementations with respect to speed of searches made over encrypted data with the same is extended in the view of decryption. Results are showcased in graphs to enable the reader to get a comparative understand of these implementations at a glance.
