Abstract
Secure operations and components may be integrated into a conventional processing system executing a standard operating system. A secure processing environment where trusted secure application code is executed may be provided for performing secure operations. In this environment, the applications and components may access all of the components in the system including secure components. An open processing environment is provided for performing conventional operations. Conventional application code may be executed in the open environment. In the open environment, access may only be provided to open components. That is, open applications and components may not be allowed to access the secure components in the system. In this way, a secure processing environment may be provided that allows secure and non-secure applications to be simultaneously executed while protecting sensitive data and operations.
