Achieving Cloud Security using Third Party Auditor, MD5 and Identity-Based Encryption

In recent years, Cloud computing has enjoyed a tremendous rise in popularity. It provides facilities for users to use cloud applications or platform without the need of any software installation and access the data or application from anywhere, with the help of internet. The cloud computing is divided into three fragments: Application, Service and Platform. Each of fragment provides different cloud services for business and individuals. Many organizations use this cloud service without any software, they run all their applications on the cloud and use on demand services. In Cloud, consumers, store their personal files or data on cloud server and consumers use that data or files whenever needed. Many consumers store or place their personal data on the cloud, so security and privacy are very important issue in cloud. These two issues can lead to a number of security concerns related to data transmission, integrity control, access control, identity management, logging and auditing, etc. Yet, research in the area of cloud computing receiving great attention from industry, academia and government. Since these domains have numerous complex issues, there are multiple open problems for research and opportunities for making noteworthy contributions, one of these issues is the data transmission in cloud computing. This proposal is concerned to overcome the security trade-off and improve the performance of data transmission and increase the security through Third Party Auditor and Identity Based Encryption.
