Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
Computer programs can use a TPM for the authentication of hardware devices, since each TPM chip has a unique and secret Endorsement Key (EK) burned in as it is produced. Security embedded in hardware provides more protection than a software-only solution. [ 31 ]
This key is used to allow the execution of secure transactions: every Trusted Platform Module (TPM) is required to be able to sign a random number (in order to allow the owner to show that he has a genuine trusted computer), using a particular protocol created by the Trusted Computing Group (the direct anonymous attestation protocol) in order ...
The TEE is used to protect the content once it is on the device. While the content is protected during transmission or streaming by the use of encryption, the TEE protects the content once it has been decrypted on the device by ensuring that decrypted content is not exposed to the environment not approved by the app developer or platform vendor.
AMD Platform Security Processor settings in an UEFI configuration screen. The AMD Platform Security Processor (PSP), officially known as AMD Secure Technology, is a trusted execution environment subsystem incorporated since about 2013 into AMD microprocessors. [1]
The exploit involves scanning through process memory in order to reconstruct a payload, which can then run code on the system. The paper claims that due to the confidential and protected nature of the enclave, it is impossible for antivirus software to detect and remove malware residing within it. Intel issued a statement, stating that this ...
Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
USB Key Mode: The user must insert a USB device that contains a startup key into the computer to be able to boot the protected OS. Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment. BitLocker does not support smart cards for pre-boot authentication.
