Optimization of Security in Public Cloud Storage Using Parallel Chunk Encryption Scheme

Abstract

Cloud services currently use many organizations to capture a large segment of today's competitive market and security issues among wearers of cloud services; the most potent service is store data in the cloud. Cloud storage seems to be data safety in terms of confidentiality and integrity, as cyber security professionals are concerned about the top storage security challenges in recent data loss and leakage. The purpose of this work is to introduce a new concept called the Parallel Chunk Encryption (PCE) Scheme; the data holders chop the file (documents, videos. etc.) into multiple chunks. Every chunk is encrypted using the Parallel Chunk Encryption (PCE) scheme and, Forward Encipher (FE) technique. The forward Encipher technique forwards the encrypted chunk to carry out the subsequent chunk encryption is necessary to perform the XOR operation in every chunk encryption it constructs to strengthen the confidentiality of data. PCE reduces the encryption time for chunks in a massive amount of size. In terms of data share and storage in a public cloud environment. The experimental results demonstrated that the PCE technique outperformed contemporary state-of-the-art methods.
