  • Transforming untrusted applications into trusted executables through static previrtualization
    Patent number: 8584248
    Abstract: A method for transforming untrusted applications into trusted executables through static previrtualization is disclosed. For example, the method receives an untrusted application and extracts a system call from the untrusted application. The method then determines if the system call is privileged or non-privileged. If the system call is privileged, the method replaces the system call with a hypercall. If the system call is non-privileged, it is replaced with a library call. The method repeats this process for additional system calls in the untrusted application to create a trusted executable. The method then forwards the trusted executable.
    Type: Grant
