Abstract
A method and system for creating flexible security control mechanisms and virtualization of nominally shared system resources. The goal is to minimize the potential for interference between concurrently executing applications in a multithreaded environment. Executable content is associated with security policies appropriate to the content, and policies are associated with the content loader; security policies are dynamically computed so that content from multiple sources can be combined to create new, yet secure, function; digitally signed executable content can bypass some security restrictions; and, nominally shared resources are managed via policies associated with the content loading mechanism.
