A Comparative Study of Cryptographic Algorithms in Cloud Environment

Abstract

Cloud is a medium for providing virtual services and resources that can be accessed and utilized easily. Along mechanism in Internet storage content is saved online, retrieved from various distributed and interconnected resources which form a cloud across the network. The prime concern faced by the Internet content system securing, as a result the owner encrypts and utilizes an search technique for accessing the data. When using a cloud storage mechanism, the third party gains the control to import your highly secured and private data to put up in the cloud. The data owners have to deal with various security issues because of entailing intense safety and confidentiality. The present paper outlines the cloud types based on cloud usage and services offered. The focus of the research being to provide secured data sharing by comparing and assessing the functionality of different symmetric encryption algorithms like parallel homomorphic encryption algorithm (PHEA), KUNodes, triple data encryption algorithm (3DEA), Also by implementing PHEA there is flexibility in data sharing, fine-grained access control, improvised average execution time and memory and data size. The research work concludes that PHEA is highly suitable for data sharing compared to other techniques of symmetric encryption.
