HESSIS: Hybrid Encryption Scheme for Secure Image Sharing in a Cloud Environment

Abstract

Cloud computing has appeared as a new computing paradigm that offers a great possibility of storing information remotely. Advancements in this new technology have reduced computational cost, the expense for requisition hosting, computation, content delivery, and storage. Cloud has many advantages but has issues or threats also. Alongside that mobile devices are making major changes in the world. Users share their confidential information on an unsecured channel which is vulnerable to attack. Security is fundamental concern over cloud computing and Cryptography is one of the best techniques for protection. The main focus of this research work is to provide the high-level security to data while storing on the cloud. In existing work, security is provided to images but that security is not high level and encryption/ decryption time also increased. In this research work, a hybrid algorithm ‘HESSIS’ is proposed to secure data while sharing. In this proposed scheme Secure hashing algorithm-3, Elliptic Curve and Advanced encryption algorithm are combined to enhance the security. Parameters calculated are index building time, candidate selection time, and accuracy.
