Intel® Server Board S5520UR and S5520URT TPS Functional Architecture

Revision 1.9 Intel order number E44031-012

hardware enhancements. Key hardware elements of this platform are:

Processor: Extensions to the IA-32 architecture allow for the creation of multiple execution

environments, or partitions. This allows for the coexistence of a standard (legacy) partition and

protected partition, where software can run in isolation in the protected partition, free from being

observed or compromised by other software running on the platform. Access to hardware

resources (such as memory) is hardened by enhancements in the processor and chipset

hardware. Other processor enhancements include:

1. Event handling, to reduce the vulnerability of data exposed through system events

2. Instructions to manage the protected execution environment

3. Instructions to establish a more secure software stack.

Chipset: Extensions to the chipset deliver support for key elements of this new, more protected

platform. They include:

1. The capability to enforce memory protection policy

2. Enhancements to protect data access from memory

3. Protected channels to graphics and input/output devices

4. Interfaces to the Trusted Platform Module [Version 1.2].

Keyboard and Mouse: Enhancements to the keyboard and mouse enable communication

between these input devices and applications running in a protected partition to take place

without being observed or compromised by unauthorized software running on the platform.

Graphics: Enhancements to the graphic subsystem enable applications running within a

protected partition to send display information to the graphics frame buffer without being

observed or compromised by unauthorized software running on the platform.

The TPM v. 1.2 device: Also called the Fixed Token, is bound to the platform and connected to

the PC’s LPC bus. The TPM provides the hardware-based mechanism to store or ‘seal’ keys

and other data to the platform. It also provides the hardware mechanism to report

platform attestations.
