摘要： A technique to provide an integrated circuit that performs memory partitioning to partition a memory into a plurality of regions, in which the memory is accessed by a plurality of heterogeneous processing devices that operate to access the memory. The integrated circuit also assigns a security level for each region of the memory and permits a memory access by a transaction to a particular region of the memory, only when a level of security assigned to the transaction meets or exceeds the assigned security level for the particular region. The integrated circuit also performs sandboxing by assigning which of the plurality of processing devices are permitted access to each of the plurality of regions. The integrated circuit may implement only the security level function or only the sandboxing function, or the integrated circuit may implement them both. In some instances, a scrambling/descrambling function is included to scramble/descramble data. In one application, the integrated circuit is included within a mobile phone.

摘要： An integrated circuit is disclosed that can be included in a host electronic device that can be commonly manufactured, where the integrated circuit can be designated (“locked”) for a specific manufacturer, thereby substantially reducing the likelihood that a third party will be able to successfully clone a host electronic device manufactured by the specific manufacturer and/or swap the chip containing the integrated circuit for one having more enabled features. The integrated circuit includes an ID module that can be programmed after fabrication. Components within the integrated circuit designate manufacturer-specific configurations (e.g., address mapping, pin routing and/or vital function releasing) based on the programmed manufacturer ID. As a result, once the integrated circuit has been programmed with the manufacturer ID, the integrated circuit will function correctly only within a host device manufactured by the manufacturer associated with the programmed manufacturer ID.

摘要： A technique to provide a hardware security module that provides a secure boundary for retention of a secure key within the secure boundary and prevention of unauthorized accesses from external sources outside of the secure boundary to obtain the secure key. The hardware security module includes a security processor to unwrap and authenticate a secure key within the secure boundary to decrypt or encrypt data and to provide data through a single interface that communicates with external sources, so that all data transfers between the secure boundary, formed by the hardware security module, and external sources are transferred only through the interface. The hardware security module ensures no unwrapped key leaves the secure boundary established by the hardware security module.

摘要： A multifunctional tool includes a main body including a connecting end with a socket. A rigid tube has a first end securely and releasably engaged with the socket of the main body. A first hose is telescopically received in the rigid tube and has an end extendible out of a second end of the rigid tube. A second hose is telescopically received in the first hose and has an end extendible out of the first hose. A magnetic member is attached to the end of the second hose for attracting and thus removing a screw from a place difficult to access. The rigid tube can be detached from the main body, and the second hose is then securely and removably held by the main body. A bit carrier carrying a number of bits is pivotally mounted to the main body and pivotable between a storage position inside the main body and an exposed position outside the main body, thereby allowing the user to choose the proper bit.

摘要： Aspects of a method and system for hardware enforced virtualization in an integrated circuit are provided. In this regard, a mode of operation of an integrated circuit may be controlled such that the integrated circuit alternates between a secure mode of operation and an open mode of operation. Various resources of the integrated circuit may be designated as open or secure, and secure resources may be made inaccessible while the integrated circuit operates in the open mode. Access to the secure resources may be controlled based on a configuration of one or more registers and/or switching elements. Resources designated as secure may comprise, for example, a one-time-programmable memory. The integrated circuit may comprise ROM and/or one-time-programmable memory that stores one or more instructions, wherein execution of the one or more instructions may control transitions between the secure mode and the open mode.

摘要： A semiconductor chip may be operable to block the debug interfaces when the semiconductor chip boots up from the boot read-only memory (ROM). The semiconductor chip may be operable to authenticate a debug certificate received by the semiconductor chip and enable one or more debug interfaces in the semiconductor chip based on the information resulting from the authentication of the debug certificate. The debug certificate may be in a form of a cryptographic public key certificate. A unique device ID which may be generated at boot and stored in the memory may be used by the semiconductor chip to authenticate the debug certificate. The device ID may be generated using the cryptographic public key that is stored in the one-time programmable (OTP) memory in the semiconductor chip and a cryptographic hash algorithm.

摘要： A semiconductor chip may be operable to receive and copy an OTP programming vector presented by the semiconductor chip programming device into its memory after it boots up from the boot read-only memory (ROM). The OTP programming vector which is a computer program may comprise an encrypted data to be programmed into the one-time programmable (OTP) memory in the semiconductor chip and may be signed with an electronic signature. The semiconductor chip may be operable to authenticate the OTP programming vector in the memory. The authenticated OTP programming vector in the memory may be executed to decrypt the data and program the data in a random data format into the OTP memory and then report the status via one or more general purpose input/output (GPIO) pins on the semiconductor chip.
