Implementation of Lashkari et al Scheme and Convergent Encryption on Cloud-Based Secure Deduplication Application

Abstract

The development and growth of data is rapidly increasing and it triggers development on storage technology namely cloud storage. In this research, implementation of Lashkari et al scheme and convergent encryption was conducted on cloud application to provide data confidentiality service and cloud storage space efficiency. Tests were conducted through comparing application that implemented this scheme with application that did not implement scheme within the same condition. Based on statistically significant comparison results, application that implements the scheme reduce 5% of storage space and takes less time for files uploading. Moreover, it can prevent attacker to obtain data illegally by implementing the convergent encryption.
