Technologies disclosed herein provide an apparatus comprising a fuse controller coupled to an aggregator. The fuse controller includes a plurality of fuses for storing a unique identifier of a device and a first secured value of a first password associated with the unique identifier. The aggregator is to receive the unique identifier and the first secured value from the fuse controller, send the unique identifier to an unlock host, receive a second password from the unlock host, compute a second secured value of the second password using a security function, and unlock one or more privileged features on the device based on the first secured value corresponding to the second secured value. In a specific embodiment, the first secured value corresponds to the second secured value if the first password is equivalent to the second password.

Secure unlock systems for locked devices

A technical problem faced when remotely controlling or debugging electronic devices is that remote control or debugging often requires a direct connection. However, debugging ports are inaccessible on many devices. Technical solutions described herein provide systems and methods for secure communication via existing communication infrastructure (e.g., public instant messenger (IM)), providing various debugging abilities including debugging and file sharing. Technical solutions described herein also provide systems and methods for debugging based on remote device memory state collection and sending for embedded or IoT devices. This solution avoids a hardware debugging connection by using a debugging methodology resident on the device to read and dump the relevant memory, registers, and other device state information in a secure and automated manner.

Remote debugging and management

Embodiments of the present invention provide for generation of SMI from ACPI ASL control method code to execute complex tasks including, but not limited to, transferring or searching through large amounts of data dynamically. Instead of executing certain tasks using limited ASL functionality, an SMI is generated in an ASL code execution path to enable usage of a CPU instruction set accessible to the SMM handler. In particular, an ACPI operation region is defined for an I/O address location capable of triggering an SMI. An ACPI control method accesses the SMI generation I/O address location to generate an SMI during ASL code execution when a predefined complex task is encountered, thus enabling the SMI handler code to advantageously execute the complex task.
