Abstract: Described herein are methods, device, and systems that provide security to various computing systems, such as, smartphones, tablets, personal computers, computing servers, or the like. Security is provided to computing systems at various stages of their operational cycles. For example, a secure boot of a base computing platform (BCP) may be performed, and security processor (SecP) may be instantiated on the BCP. Using the SecP, an integrity of the OS of the BCP may be verified, and an integrity of a hypervisor may be verified. A virtual machine (VM) may be created on the BCP. The VM is provided with virtual access to the SecP on the BCP. Using the virtual access to the TAM, an integrity of the guest OS of the VM is verified and an integrity of applications running on the guest OS are verified.
