VISHNU: A Software Behavior Trustworthiness Control Method Based on DRTM

Based on secure execution technology provided by Late Launch and modern computer hardware, we propose a software dynamic trustworthy control method, which purpose is to solve trust control problem of key operations at software runtime through strong isolation. Key operations indicate operations that directly access to sensitive data. This method can prevent malware program accessing to sensitive data and key operations in protected processes for security, even that computer´s application or operating system has been invaded or controlled. We developed a prototype system called VISHNU and take Online Payment as an example to validate the effectiveness of the method.
