Concurrent and Independent Access to Encrypted Cloud Databases

Abstract

We are moving to future where some or even most of our data will exist in cloud, because cloud provides stored data to be accessed at anywhere through networks. Since data in cloud will be placed anywhere, because of the critical nature of the applications, it is important that clouds be secure. The major security challenge with clouds is that the owner of the data may not have control of where the data is placed; it will create other problems also like data confidentiality and bottleneck. This paper presents a new technique that provides data confidentiality and concurrent access of encrypted cloud database with resolving the bottleneck problem .
