A secured cloud storage technique to improve security in cloud infrastructure

Security in cloud computing is considered to be the most challenging research domain where most of the solutions remain vulnerable. Availability of data in cloud to every other components of cloud made it difficult to protect it from external sources. The risk of malicious insiders in cloud and failing of cloud services have received a strong attention from many companies. Security ensures confidentiality, integrity and availability. Security has the characteristics of a complement to reliability. This work proposes a new system where data can be stored with high security using Storage Efficient Secret Sharing Algorithm (SESS) implemented using Shamir's Secret Sharing (SSS) approach. This approach ensures that security for data can be achieved by splitting data into K number of parts and need of every partition of data to construct original data proves that this algorithm is computationally strong against any attack. Implementing SSS approach for application processing, is computationally inefficient. This paper presents a detailed implementation of SESS using SSS approach with Dynamic Software Module (DSM) to secure data stored in cloud environment to improve security in cloud infrastructure.
