Integrated physical and cryptographic security system for serial console, serial data communication, and ethernet ports

Abstract

An integrated physical and cryptographic security system for securing serial console ports, serial data communication ports, Ethernet ports, or other connector ports of electronic devices. A connector port locking apparatus has a main shell and a plug replicator nose for being received into the connector port. The plug replicator nose has opposed ramp surfaces with a portion sloped in a ventral-dorsal direction. Lugs project oppositely from a locking expansion member into engagement with the ramp surfaces, and a locking tooth projects dorsally from the locking expansion member. A motor and expansion bolt cooperate to propel the locking expansion member relative to the plug replicator nose, and the ramp surfaces induce extension and retraction of the locking expansion member dorsally into a locking position and ventrally into an unlocking position. Command signals received by wire or wirelessly actuate port locking and unlocking processes only through cryptographic multifactor authentication.
