An automobile, vehicle, vessel or other device may include a plurality of modules, software applications, computer program products, controllers or other logically executing entities to facilitate controlling, implementing or otherwise enabling various operations according to computer-readable instructions, code or other information stored within a memory, such as within a file or other memory construct. A controller having capabilities sufficient to facilitate updating, modifying, creating or otherwise manipulating such stored files and/or corresponding instructions is contemplated.

Module updating device

A method for verifying electronic software code integrity may comprise providing a list of encryption keys to a client, encrypting a software code packet using one of the plurality of encryption keys, delivering the encrypted software code packet to the client, and informing the client to choose an encryption key for decryption based on the specific time factor Each encryption key on the list may correlate to a respective time factor The one of the plurality of encryption keys may be chosen from the list based at least in part on a specific time factor

System and methods for remote maintenance in an electronic network with multiple clients

Generally, this disclosure describes devices, methods and systems and for securely updating software on a mobile platform using trusted hardware based authentication. The device may include an image update module configured to receive a software update image from an update server, the image update module executing at an operating system (OS) level; a critical component database configured to identify critical software components associated with the secure operation of the device; a secure update application module configured to verify the inclusion of the critical software components in the software update image prior to installation of the software update image on the device; and a trusted execution environment (TEE) configured to restrict control access and data access to the secure update application module and the critical component database, the restriction enforced against the OS and against modules executing at the OS level.

Mobile platform software update with secure authentication

Among other things, a determination is made of and ability of an autonomous vehicle to safely or robustly travel a road feature or a road segment or a route that is being considered for the autonomous vehicle as of a time or range of times. The route conforms to properties of stored road network information. The road feature or road segment or route is eliminated from consideration if the computer has determined that the road feature or road segment or route cannot be safely or robustly traveled by the autonomous vehicle. The determination is based on analysis of performance of the autonomous vehicle.

Route Planning for an Autonomous Vehicle

A system configured to manage battery energy of a mobile device includes a primary mobile device and at least one peer device. The primary mobile device includes a power unit, a main communication module to electrically communicate with a peer device, and a peer assisted module in electrical communication with the power unit and the main communication module. The peer assisted module determines an energy level of the energy unit, and determines a task to be executed by the peer device. The peer device receives the task transmitted from the primary mobile device. The peer device further includes a peer process management module that executes at least one computation that completes the task, and communicates a completed task to the primary mobile device.

Peer assisted mobile device battery extension system

A network based installation management system that dynamically manages secure software installation on a client The server is configured to determine the software required and prepare an appropriated response containing the list of software and an information file containing the respective attributes of the list of software The server encoded this response and the encoded response is transmitted to the client The client on receiving the response is configured to authenticate the response and install the encoded response after authentication Highly accurate and reliable software installation using the network based installation management system may be achieved using a respective hardware element on the client and the server, which is configured to encode and decode a request and/or response suitably thereby providing a high level of security and trust in an un-trusted network environment

Method and system for software installation

A trusted device having virtualized registers provides an extensible amount of storage for hash values and other information stored within a trusted device. The trusted device includes a buffer to which registers are virtualized to and from external storage, by encrypting the register values using a private device key. The registers may be platform control registers (PCRs) or other storage of the trusted device, which may be a trusted platform module (TPM). The registers are accessed in accordance with a register number. When the externally stored values are retrieved, they are decrypted and placed in the buffer. The buffer may implement a cache mechanism, such as a most recently used algorithm, so that encryption/decryption and fetch overhead is reduced. A register shadowing technique may be employed at boot time, to ensure that the trusted device is not compromised by tampering with the externally stored virtualized registers.

PROBLEM TO BE SOLVED: To provide a trusted device which has an extensible register and a method for protecting a register extension in order to resolve a restriction of a memory device in the trusted device. SOLUTION: The trusted device contains one buffer, and the register to the buffer is virtualized to and from an external storage device by enciphering a value of the register using a private device key DPK. The register may be another memory device in a platform control register (PCR) or its trusted device. It may be a trusted platform module (TPM). The register is accessed according to a register number. When a value stored outside is retrieved, their encryption are released and they are set on the buffer. COPYRIGHT: (C)2008,JPO&INPIT
