Abstract: A security verification system may acquire first authorization information, wherein the first authorization information defines an access right to store data in a trusted platform module (TPM) of the computing device. A system may generate an index of an allocated memory location of the TPM and second authorization information using the first authorization information, wherein the second authorization information defines an access right associated with the index. A system may receive a request from a hypervisor to initiate a virtual machine. A system may transmit the second authorization information to the hypervisor. A system may store an initial state of the virtual machine at the index using the second authorization information.

Abstract: A data processing system supporting a secure domain and a non-secure domain comprises a hardware component, and a processor device having operating modes in the secure domain and non-secure domain, the processor device to execute a secure application in the secure domain. The hardware component has a property having a secure state. The property of the hardware component in the secure state may only be reconfigured responsive to instructions received from the secure domain. The secure application is operative to implement a configuration service to configure the property of the hardware component in the secure state, responsive to a request received from the non-secure domain according to an application programming interface associated with the secure application.

Abstract: In an example, a computing device is described. The computing device comprises a communication interface and a processor. The processor is to determine whether a signature, produced by a signer, is derived from a free state under a stateful signature scheme. The free state is a state that has not been used as an input to generate a signing key. The signature is encrypted by the signer. The processor is further to, in response to determining that the signature is derived from a free state, decrypt the encrypted signature. The processor is further to transmit the decrypted signature to a recipient via the communication interface.
