Key Insertion and Splay Tree Encryption Algorithm for Secure Data Outsourcing in Cloud

Cloud computing is used broadly in various services which contain storage platform and very easy to get to vast calculation. Due to low cost, strength, elasticity and ubiquitous nature, cloud computing changes the path entities to manage their data. In cloud environment, secure outsourcing is one of the active research areas, as the cloud environment can´t be trusted. The situation becomes complex when the outsourced data sources in a cloud environment are covenant with multiple outsourcers who are available with different access rights. Key management is one of the important aspects for securing outsourced data in cloud environment. In this paper, a new encryption algorithm called Key Insertion and Splay Tree encryption (KIST) proposed. This algorithm makes use of an asynchronous key series and splay tree for encryption. This encryption approach provides better key management approach for validating the users in the cloud. The experimental result shows that it is very efficient in providing authentication and security to the cloud data.
