A device receives a request from a user to manage a Mobile Network Operator (MNO) profile stored in a smart card within the device, wherein the MNO profile includes one or more network access credentials for accessing a wireless network. The device performs a Completely Automated Public Turing Test to tell Computers and Humans Apart (CAPTCHA), wherein the CAPTCHA includes receiving input from the user, and authenticates the user as a human, and not a bot or other automated activity, based on the CAPTCHA and the input from the user. The device receives, from a network node external to the device responsive to the authenticating, a MNO profile management code, and manages the MNO profile based on the received MNO profile management code.

Protected smart card profile management

A remote device management, diagnostics, and self-installation architecture employs multiple wireless links, which may include a local wireless link and a remote wireless link. The architecture employs cellular channels for remote management of customer premises equipment (CPE). Within the architecture, test devices may operate on the CPE. As examples, the test devices may include a cellular radio, or the test devices may be in communication with another device that includes the cellular radio.

Auxiliary channel remote device management, diagnostics, and self-installation

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.

Method and system for securely programming OTP memory

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.

Method and system for hardware enforced virtualization in an integrated circuit

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.

Method and system for securely protecting a semiconductor chip without compromising test and debug capabilities

A lifting tool for lifting an internal combustion engine having an intake manifold, the lifting tool including a mounting plate for connecting to the intake manifold of the engine, the mounting plate having a plurality of holes therein aligned with bolt holes or studs in the intake manifold, a 'U'-shaped bracket connected to the mounting plate for receipt of a hook or chain connected to a lifting device such as a chain hoist, and a plurality of safety chains connected to the 'U'-shaped bracket for connecting to the engine to prevent the engine from falling to the ground if the 'U'-shaped bracket should separate from the mounting plate or if the mounting plate should separate from the engine while the engine is being hoisted.

Engine lifting tool

A trailer light assembly for use on boat trailers, which assembly is capable of maintaining a light fixture component of the assembly at such a height that the light fixture is not brought into contact with the water when the trailer is being used to launch or retrieve a boat. Maintenance of the desirable height is achieved by having the light fixture move upward or away from the water in response to a flotation device which is attached to the light fixture. The trailer light assembly may also feature a double-acting pivot point which will allow the flotation device to survive lateral forces thereon.
