Abstract: Methods, systems, and media for remote control of a vehicle device and vehicle lockout notification are disclosed. Embodiments comprise a method of creating a secure bidirectional communication link between a remote access device and a central locking unit (CLU) of a vehicle, enabling the central locking unit to authenticate a user of the remote access device to manipulate a device of the vehicle. In some embodiments, the CLU may wait for an access attempt from a mobile device. In other embodiments, the CLU monitor vehicle conditions, detect a lockout condition, and alert the user before authenticating and granting vehicle access. Embodiments utilize private and shared key encryption methods to facilitate securely passing an access code between the CLU and the remote access device. Some embodiments authenticate the user by voice verification, while other embodiments may use personal identification numbers.

Abstract: A computer implemented method for recovering a partition context in the event of a system or hardware device failure. Upon receiving a command from a partition to modify context data in a trusted platform module (TPM) hardware device, a trusted platform module input/output host partition (TMPIOP) provides an encrypted copy of the context data and the command to the TPM hardware device, which processes the command and updates the context data. If the TPM hardware device successfully processes the command, the TMPIOP receives the updated context data from the TPM hardware device and stores the updated context data received in encrypted form in a context data cache or a non-volatile storage off-board the TPM hardware device. If the TPM hardware device fails to successfully process the command, the TMPIOP uses a last valid copy of the context data to retry processing of the command on a different TPM hardware device.
