Abstract: The present invention is directed to a security device for securing computer ports that are in use and also for securing unused computer ports of an electronic device. The invention is also directed to physically blocking access to the computer port. The security device typically comprises a securing mechanism configured for releasably locking the security device within the computer port. The security device further comprises a controlling mechanism that is configured to cause the securing mechanism to move between a locked state and an unlocked state. The security device is further configured to establish an operative connection with an external computing device and authenticate the device via a communication port of the security device.

Abstract: Described herein are systems and methods for securing and regulating access to physical input/output (“I/O”) ports on a computing or network device. Novel devices and methods for authenticating a user or device while retaining operational security are disclosed. In some embodiments reauthentication is not required unless a device is removed or replaced, even if the attached computing or network device is powered down or rebooted. The novel devices and methods are further enhanced by utilization of a locking mechanism and control scheme that utilizes a shape memory alloy.

Abstract: Described herein are systems and methods for securing and regulating access to physical input/output (“I/O”) ports on a computing or network device. Novel devices and methods for physically securing an I/O port using a memory shape alloy is disclosed. The compact form factors required in this application make the utilization of memory shape alloys particularly advantageous as they require minimal space.
