This seminar discusses a new technology, the next-generation secure computing base (NGSCB), which makes it possible to dynamically create a security perimeter around disparate software components by separating the operating system from security components”all without requiring drastic changes to existing personal computers.Trusted distributed computing relies on the ability to construct a security perimeter around an arbitrary trusted computing base (TCB) in which data remains invulnerable to attacks from both users and software.
