Security is an integral part of the chip, instead of being an add-on.
Return to Top 2. The InterTrust TrustChip Architecture works by establishing a protected memory space in which an appliance's firmware can run, and by providing a security kernel that makes services available to that firmware without giving it unrestricted control over the hardware. The kernel allows appliance developers to create their own firmware without any special security constraints, because the kernel controls the firmware's operation. It runs securely. That is, once the kernel is initialized, the rest of the firmware runs under the kernel's control.
