Abstract
A method for enhancing security of a computer system is provided. The computer system may include a plurality of microprocessors and a security management processor for managing execution of applications in isolation on the plurality of microprocessors. Each of the plurality of microprocessors is communicatively coupled to the security management processor. An operating system is installed on one of the plurality of microprocessors. An application is installed on the same microprocessors. The application and the operating system are combined into an OS/application pair (or pair). The pair is encrypted. The encrypted pair is then stored in a mass storage of the computer system. The mass storage is communicatively coupled to the security management processor. A graphic user interface of the security management processor may be used to launch the application on any of the plurality of microprocessors by loading the stored pair to that microprocessor. Data produced by the application may be encrypted and stored in the mass storage when saved. The stored data produced by the application may be not accessible by other applications without authorization.
