Towards a DHT Networks and Safe File Sharing Scheme in Cloud Storage Service

Abstract

Safe file sharing mechanism in cloud storage is one of the most significant elements that affects the development of security technology. With application of homomorphic key agreement mechanism, Shamir secret sharing algorithm, Bloom Filter and B-tree search algorithm and Rsync data updating algorithm, a safe file sharing scheme in cloud storage is established based on cloud storage infrastructure of DHT networks. Under the circumstance of cloud storage, the scheme can make full use of the sharing mechanism and achieve the confidentiality and integrity of the file. Based on DHT networks, the analysis and test of data sharing are conducted in the paper. Together with file upload and download, the test of data encryption and decryption is done on the basis of Dropbox. As the result shows, the scheme puts forward a safe and effective solution to safe file sharing in cloud storage.

File retrieval and storage in the open source cloud tool using digital bipartite and digit compact prefix indexing method

“…Many researchers introduced algorithms for search and retrieval of data in cloud data centers. Lu and Shen introduced an algorithm called key negotiation. This algorithm works in the shared cloud storage system with distributed hash table (DHT)–based networks.…”
