Data exchange is a core part of all cloud systems
so it becomes necessarily important to control access to data that are confidential and whose integrity influences the state of the system at any time.It can be proven that the administrator in a
IaaS can easily perform some hidden and malicious
task on unsuspecting customer machine. This is
attributed to the fact that he/she possesses the root
privilege to do so and forms an attack. A cold boot
attack can easily be lauched amongst other attacks by the privilege user or system administrator.A simple attack scenario could be that a customer pays a virtual machine at Amazon EC2 (Provider) and the systemadmin (Privilidged User) who is, for instance, threatened to be fired, has access to the same virtual machine state, this priviledged user can easily leak customer’s data. There is a need to secure the computation state during communication and storage and we achieve this through the implementation of a trusted platform.
