Encryption Technique for a Trusted Cloud Computing Environment

Abstract

Cloud computing has reached a certain level of maturity which leads to a defined productive state. With varying amount of computing power present with everyone, it has become necessity of the hour to use cloud computing systems. It helps us to store our data within a virtual cloud structure. When we use the cloud storage mechanism, the computing power gets distributed rather than being centralised. The whole system uses the internet communication to allow linkage between client side and server side services/applications. The service providers may use the cloud platform as a web service platform or a data storage architecture. The freedom to use any device and location for cloud management is an added advantage for any user. Maintenance of such systems is also easy as installation of resources aren't required in each and every system which is using cloud services. But along with varying flexibility and multi tenancy in usage comes the question of reliability and security. As in public hosting, the client is totally unaware of the security strategies applied by the service provider, it creates a necessity for the end user to save the data from expected threats. One cannot totally rely on the quality of service (QoS) which is guaranteed by host servers. When we look at the security of data in the cloud computing, the vendor has to provide some assurance in service level agreements (SLA) to convince the customer on security factors. This paper describes a schema that ensures encryption of data using Advanced Encryption Standards. By doing so, the customer services can become quiet secured and thus can help in further enhancement of the cloud computing standards.
