Electromechanical USB Locking Device for Port Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB port protection methods lack effective prevention of cyber attacks, as they can be bypassed through brute force, are not secure when the host computer is powered off, and do not allow for future use of the USB ports without damaging the device or jack, and they suffer from key management and monitoring vulnerabilities.
Innovation Solution
An electronic USB security device with an electromechanical solenoid lock driven by a security controller, which is coupled to the USB interface and requires authentication through a remote-control receiver or host emulator to ensure secure locking and unlocking, providing a positive locking mechanism and monitoring capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software-based USB port locking is used, then USB ports can be locked and managed, but the security can be bypassed through brute force or administrator permissions
Solution Approach 1:
The patent replaces software-based USB port locking with a hardware-based electromechanical locking mechanism. The locking device includes a physical lock that can be engaged to block access to the USB port, and an electromechanical actuator that can be controlled to lock or unlock the port. This hardware-based approach eliminates the security vulnerabilities of software-based solutions, as the physical lock cannot be bypassed through software attacks or administrator permissions.
2Reliability
If a mechanical lock for USB port is used, then physical access is prevented, but the lock cannot be removed without damaging the device or jack
Solution Approach 1:
The patent implements a dynamic locking mechanism that can transition between locked and unlocked states. The electromechanical actuator can be controlled to engage or disengage the physical lock, allowing the USB port to be securely locked when needed and easily accessible when required. This dynamic capability eliminates the need to damage the device or jack for removal, as the lock can be electronically controlled to open.
3Reliability
If an electromechanical solenoid lock is used, then secure locking and unlocking is achieved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single USB device. The locking device includes both USB communication functionality and electromechanical locking functionality in one integrated unit. The device can communicate with the host computer through the USB interface while simultaneously controlling the lock mechanism. This multi-functionality reduces the need for separate locking devices and simplifies the overall system architecture.

AI summary
The invention relates to an electronic USB security device (20), comprising:a plug (13) capable of interfacing the electronic USB security device (20) with a USB jack (31) of a host device (30), having at least one locking tooth (8) shaped to lock inside a shielding tab hole (34) of said USB jack (31), thus locking the electronic USB security device (20) to said host device (30); and a solenoid (24) capable of enabling and disabling the locking of said at least one locking tooth (8) to said shielding tab hole (34) of said USB jack (31). USB ports present risk of data leak from computers. The invention provides an electromechanical USB port protection device capable to mechanically block unused USB ports, thus preventing the connection of any USB device to that port. Removal of the device requires electrically energizing the lock using for example a security code. Security software provides scalable and secure centralized keys management. The device provides clear and continuous user visual indications when device is secure. A device derivative secures USB cable to the computer USB port. Another device derivative filters and secures a connected user peripheral device, for example a USB locking device that only allows a connection of USB mouse or keyboard.
