Abstract:
1. A security module comprising: a first communication port connectable to a host device; a first storage device; a first decryption means; a hardware or software state module, which is configured to detect activity on a communication port and to determine, according to the activity, a state of said state module; a second communication port; and an insulating circuit placed in series with the second communications port and configured to electronically isolate said second communication port, said insulating circuit being controlled by the state module; wherein the insulating circuit includes tri-state or bidirectional MOSFET elements; and where at least a portion of a physical connection path including the first communication port is different from at least a portion of a connection path including the second communication port; wherein the security module is configured to receive a security message via the first or second communication port, and modify a state of said state module defining an accessibility of the security module to the host device via the second communication port in response to the security message.
