Abstract: Various embodiments of the present disclosure provide systems and methods for securing electronic devices, such as financial payment terminals, to protect sensitive data and prevent unauthorized access to confidential information. In embodiments, this is achieved without having to rely on the availability of backup energy sources. In certain embodiments, tampering attempts are thwarted by using a virtually perfect PUF circuit and PUF-generated secret or private key within a payment terminal that does not require a battery backup system and, thus, eliminates the cost associated with common battery-backed security systems. In certain embodiments, during regular operation, sensors constantly monitor the to-be-protected electronic device for tampering attempts and physical attack to ensure the physical integrity.

Abstract: A method and apparatus for deactivating an identification device or RFID tag, such as an e-passport or an ID card that has been revoked, has expired, or is invalid. A programmable memory circuit is coupled to a controlling circuit that is coupled to a shorting circuit that may activate or deactivate the operation of the identification device.

Abstract: A bi-directional serial interface for serial communication having a control line to facilitate the transmission of data to and from a microcontroller and a serial interface module. The control line can be used by both the microcontroller and the serial interface module to send controlling signals such as start signals, receipt acknowledge signals, error signals, and stop signals. By having a dedicated control line that can be used by both the sending device and the receiving device, the present invention allows the initiation of a communication session by either the microcontroller or the serial interface.

Abstract: The present invention allows the use of low speed USB reader/connector to be use for full speed and high-speed transmission by introducing an accurate clock element into the smart card. In addition, the present invention eliminate the need of having a clock element in any USB compatible reader/connector, making the reader/connector a much simpler device that can be manufactured in a lower cost.
