摘要：During the file access and storage the files are travelling through the secured network to the host, thus the security in the files are required to incorporate with the files. For securing the files in the cloud various cryptographic approaches are used but most of them increase the computational cost of file storage. Thus a new technique is required to develop which efficiently used for data storage and data access.Therefore the presented work is intended to find an approach by which the security in file hosting and management can play an important role. Therefore the given technique incorporates the SHA and AES encryption algorithms to secure the files in the server and for increasing the transfer rate of the data the file is used. The implementation of the proposed secure technique is performed using the JAVA technology and their performance in terms of time complexity and storage overhead computed.The results claim the efficient methodology of file hosting and distribution in the cloud storage additionally that is efficient during the fast upload and downloads. Thus the proposed technique is adoptable and secure for secure storage services.
