Embodiment Construction

[0052] Firstly, the computing environment according to the present invention is introduced. The computing environment according to the present invention generally includes computing hardware with an open architecture (such as but not limited to, Intel X86 architecture) and a software stack.

[0053] Generally, the hardware architecture includes a Trusted Platform Module (TPM), a Program Control Unit (PCU), a Memory Management Unit (MMU) and an Input / Output Memory Management Unit (IOMMU).

[0054] When starting the software stack of the computing platform, the trusted platform module can measure the Root Trusted Computing Base (RTCB, Root Trusted Computing Base), and store the measurement result in the trusted platform module for future verification. The method and device for measuring, storing and verifying the RTCB by the trusted platform module are common techniques in the art and will not be described here. See, eg, US Patent Application filed by the present applicant (Atto...

Abstract

The invention provides a method for isolating and protecting a computing environment in a protected process by using root trusted computing base (RTCB), which comprises an initialized protected process; controlling the dynamic computing environment in a protected process to prevent the dynamic computing environment from being used illegally; monitoring the use of a memory management unit (MMU) and isolating and protecting the memory space in a protected process; and monitoring the use of an input / output memory management unit (IOMMU), and controlling the interaction operation conducted by peripheral equipment with the protected process through the IOMMU. When the method is used, other processes beyond a safe access policy collection of the protected process are prevented from accessing the memory space through the MMU or any input / output (IO) equipment from accessing the memory space according to the memory space distributed to the protected process when the protected process is run, and thus, real safe isolation can be formed.

Description

technical field [0001] The present invention relates to the field of security of computing environments, and more particularly, to methods and systems for isolating computing environments to protect software applications executing in the isolated computing environments. Background technique [0002] Currently, it is well known that a large amount of software codes and data in clear text are usually stored in a computing environment. To prevent compromise of execution integrity and / or data confidentiality from any unauthorized access, some software code and data need to be run in an isolated secure computing environment. Strong isolation is an important security requirement for a backup device service configuration platform, such as a server in cloud computing. [0003] A virtual machine (VM) has been widely used as an isolation platform, and security isolation is provided through the natural separation between various virtual machines in the application.
