1. Memory curtaining Memory curtaining refers to a strong, hardware-enforced memory isolation feature to prevent programs from being able to read or write one another's memory. Today, an intruder or malicious code can often read or alter sensitive data in a PC's memory. In the trusted computing design, even the operating system should not have access to curtained memory, so an intruder who gains control of the very operating system would not be able to interfere with programs' secure memory. Although memory isolation can be achieved in software, this requires some combination of rewriting operating systems, device drivers, and possibly even application software. Implementing this feature in hardware instead permits greater backwards compatibility with existing software and reduces the quantity of software which must be rewritten. (In general, many of the security benefits of trusted computing could be achieved in some form simply by rewriting software, but this appears impractical to some.) |
