Cloud computing will only gain acceptance among the general people and to organizations when the trust is ensured. Both the Cloud service provider and the cloud customer must be trustworthy. Trust can only be ensured for the cloud when cloud activity are monitored effectively to aid forensic experts in Digital Forensic Investigation. In this respect cloud meta-data and provenance can be used to aid the digital investigation process. I have a number of publications regarding the integrity and security of cloud computing. Here are those:

2. https://www.researchgate.net/publication/259006208_Cloud-Niagara_A_High_Availability_and_Low_Overhead_Fault_Tolerance_Middleware_for_the_Cloud

3. https://www.researchgate.net/publication/260001378_Active-Threaded_Algorithms_for_Provenance_Cognition_in_the_Cloud_preserving_Low_Overhead_and_Fault_Tolerance

I have been conducting research in cloud computing security, trust and integrity for the last 2 and half years. Please get in touch if you need help.

Dear Nadeem, no doubt security in cloud computing is hot topic of research of this emerging field. I identify the key security issues of cloud computing according to my knowledge and experience as follows. As we know that resources are shared by virtualization techniques among the users of cloud computing keeping each resource in full isolation is ideal. Common cryptographic approaches are not adequate as data is to be stored on long term basis. Others are also to be described here, but i can suggest you to review literature or survey papers. Thanks

You can download the review of cloud security from main publishing houses such as springe,ieee
