A secure insert comprises a shell including a lid and a container configured to receive and encase one or more circuit cards, wherein the shell is further configured to be inserted into and engage a card slot area of a chassis. A bridge connector is disposed inside the shell and configured to couple the one or more circuit cards to a chassis connector. A tamper sensor is disposed inside the shell and configured to detect unauthorized tamper events.

This disclosure describes techniques that may prevent cryptographic devices, including both encryption devices and decryption devices, from producing a power signature that can be used by attackers to deconstruct a cryptographic algorithm and extract a cryptographic key. The techniques may include an external power supply charging an internal, dedicated power storage element; temporarily gating off the encryption device from the external power supply; configuring a cryptographic logic unit to perform a cryptographic algorithm from power stored in the power storage element while the external power source is gated off; and then recharging the power storage element upon the cryptographic logic unit completing an iteration of the cryptographic algorithm.
摘要:
In some examples, a system includes a data storage device that stores data and a monitor device that monitors a physical domain in which the data storage device is located and conditions access to data stored by the data storage device based on communication between the monitor device and the data storage device. In some examples, the system is configured to impede access to the data when at least one of operation the monitor device fails or the monitor device is attacked. Additionally, in some examples, the monitor device is configured to restrict access to the data when the monitor device is engaged and an attacker attempts to access the data storage device directly.

A secure connector is provided. The secure connector comprises a casing; a tamper sensor disposed inside the casing and configured to detect unauthorized tamper events; and one or more conductors configured to carry signals, the one or more conductors passing through the tamper sensor.
摘要:
An optical anti-tamper system including a light emitting layer located within a chassis, a light detecting layer located within the chassis and one or more detectors optically coupled to the light detecting layer. The one or more detectors are in communication with an alarm. The alarm is operable to transmit a tamper-event warning signal if an increased light level is detected by at least one detector.

A cooking apparatus ventilation system which evacuates smoke and vapors to allow indoor cooking. Air is evacuated through ventilation channels which surround all but one side of the cooking surface. A layer of air is directed from the fourth side across the cooking surface to push the smoke and vapor into the ventilation channels. A portion of the evacuated air is recycled back across the cooking surface to enhance the flavor of the food being cooked.

摘要:
A device is described for positioning a reinforcing cage within a cylindrical concrete pipe form. The device comprises a horizontally movable slide which may be moved inwardly into the form for engagement with the cage. A cam is secured to the slide for moving the slide inwardly and outwardly relative to the form. An air cylinder is pivotally connected to the cam for pivotally moving the cam. An adjustable stop is located in the pivotal path of the cam to limit the inward movement of the slide. A plurality of the devices are mounted on the form in a radially spaced and vertically spaced manner.
