Optimal attribute based encryption for secure data storage on Social Distributed Environmen

Abstract

 Preserving privacy and security in cloud computing is a big challenge. There are a lot of systems that can provide cloud computing services. Cloud Computing is a service that is quickly increasing its development in the IT industry in recent years. In a public cloud environment, users transfer their data to a public cloud server and cannot control its remote data. Thus, information security is one of the significant problem in public cloud storage, such as high computation cost, confidentiality of the data, integrity, availability and authenticity. To resolve this, in this paper, optimal attribute based encryption (OABE) is proposed. ABE aims to strengthen the sensitive data confidentiality in public cloud storage. To enhance the ABE algorithm, the key values are optimally selected with the help of Beetle Swarm Optimization algorithm (BSO). BSO is a new meta-heuristic algorithm, which is based on the foraging principle of the beetle.
