Trustzone hypervisor

ARM TrustZone technology provides system-wide hardware isolation for trusted software.To accomplish this we will use an ARM security extension called TrustZone. Hypervisor solution: Hypervisor switching between two instances of the microkernel. Open Virtualization - ARM TrustZon

How is then an extra bit making all that difference in terms of security.ARM TrustZone software provided by Open Virtualization can be easily integrated into smart phones, set top boxes, residential gateways and other ARM-powered devices.The Truth about TrustZone: Exploring the Impact of Recent Advances for Premium Content.We have lots of relevant tutorials and FAQs over in the ARM Development.

With Cortex-A15, ARM introduced hardware virtualization support.This mode of operation supports virtually all ARM-based systems currently in production today.The SierraVisor Hypervisor is ideally suited for equipment vendors that are developing next generation systems with Cortex-A15 processors.SierraVisor Hypervisor for ARM offers equipment vendors flexible open source and commercially licensed software for embedded virtualization.


The guest operating systems are aware of the fact that they are running on top of a hypervisor, so minor modifications must be made to the guest operating systems.

Security Views: TrustZone and Trusted Execution Environment

Sierraware has released a flexible, reliable hypervisor for ARM-based systems that supports not one, not two, but three distinct modes of operation.For multiple CPUs, it also has an advantage of one centralized place to restrict access so it is simpler.

With all three modes of operation, guest systems can still access the secure world provided by ARM TrustZone technology, so each guest system can protect sensitive data like DRM applications, encryption keys, and NFC payment applications.The SierraVisor Hypervisor Development Toolkit enables equipment manufacturers to choose the right hypervisor for their processor architecture and virtualization requirements.Ie, they will always tag transactions with an NS bit (the 33 rd bit ).Besides DMA Masters, alternate CPUs also pose a threat to memory partitioning.DMA Attack explanation: In contrast to a hardware bit, a Hypervisor usually uses the CPUs MMU to limit software access.
