Launch Time Application Security: The Trusted Approach

In the day to day lives of human beings commodity computers are increasingly used to access banking transactions, sending sensitive e-mails, accessing personal and confidential information from remote systems, where it becomes the prime necessity to assure the user that security sensitive operations executes always on secure and trusted state of system. The emergence of the Trusted Platform Module (TPM) has added to the security feature of a computer. Much work has been done to ensure the integrity of the system using a TPM. But what happens when the applications running on top of the Trusted System are malicious? The sensitive data provided to such applications becomes vulnerable for exploit. We propose a system which notifies the user if the integrity of an application is violated and stops it. The system makes use of the functionalities of the TPM chip.
