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. 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 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.
