Abstract

The security level in existing workstation and server systems is not sufficient for most applications in a network environment. The processors only provide basic multitasking support, and any other security enforcement has to be carried out in the software layers. It is shown why stronger hardware security must be provided by the processor, and how it can be realised to limit the execution time overhead to 2%. This overhead is only required for the critical parts of the code that need strong protection.
