Abstract: A package includes a chassis, a plurality of components arranged within the chassis, a plurality of RFID devices, and at least one processing device. The RFID devices are arranged at a plurality of locations to form an array configured to authenticate compliance of the actual configuration of the package with a model configuration. The processing device is configured to communicate with the RFID devices, determine if the actual configuration of the package is in compliance with the model configuration based on communications with the RFID devices, and set an operational mode of one or more of the components of the package in response to determining if the actual configuration of the package is in compliance with the model configuration.

Abstract: In one embodiment, a system comprises application-specific functionality, anti-tamper functionality to detect an unauthorized attempt to interact with the application-specific functionality; and a hardware key interface to communicatively couple the system to a hardware key. An attempt to interact with the application-specific functionality is considered unauthorized if an authorized hardware key is not communicatively coupled to the hardware key interface when the attempt occurs.

Abstract: In one embodiment, a system comprises JTAG functionality that implements at least a portion of a JTAG protocol. The JTAG functionality supports a test data in (TDI) line, a test data out (TDO) line, a test rest (TR) line, a test mode state (TMS) line, and a test clock (TCLK) line. The system further comprises a debug interface to communicatively couple the system to a debug device external to the system. The debug interface comprises a transmit (TX) line, receive (RX) line, and a clock (CLK) line. The system transmits data output by the JTAG functionality on the TDI input on the RX line of the debug interface and receives data from the debug device on the TX line of the debug interface and provides the received data to the JTAG functionality on the TDO line, TR line and the TMS line.

Abstract: In one embodiment, a system comprises application-specific functionality, debug functionality, and a debug interface communicatively coupled to the debug functionality to communicatively couple the system to a debug device. The debug functionality encrypts data transmitted by the system over the debug interface.

Abstract: In one embodiment, a system comprises an enclosure, at least one item enclosed within the enclosure, and at least one optical medium disposed between the enclosure and the at least one item. The at least one optical medium is arranged in a pattern such that the at least one optical medium substantially encloses the at least one item. The system further comprises a generator communicatively coupled to a first portion of the optical medium. The generator generates a pseudo-random sequence of bits. The pseudo-random sequence of bits is optically transmitted over the optical medium. The system further comprises a detector communicatively coupled to a second portion of the optical medium. The detector detects any portion of the pseudo-random sequence of bits received at the second portion of the optical medium.

Abstract: In one embodiment, a system comprises debug functionality, a debug interface communicatively coupled to the debug functionality, and a hardware key interface. Communication with the debug functionality over the debug interface is not permitted if an authorized hardware key is not communicatively coupled to the hardware key interface.

Abstract: An improved system and method for protecting sensitive electronic equipment or components against unauthorized access, by detecting and also reacting to unauthorized intrusions into the enclosures for the sensitive electronic equipment or components is disclosed. For example, a protective system for protecting sensitive electronic equipment or components against unauthorized access is disclosed that includes a fiber optic cable mesh or network attached to, or embedded in, the walls of the enclosure for the electronic equipment or components. A continuous signal or burst is applied to the fiber optic cable, which is coupled to an optical signal detection device. Thus, any attempt to remove or penetrate the walls of the enclosure interrupts the signal in the fiber optic cable, and the interruption of the signal is detected by the optical signal detection device.
