Abstract: PURPOSE: A tamper resistance device and a method for operating the same are provided to prevent data stored in a memory of an electronic device from being flowed out by an attack from an exterior or an illegal treatment. CONSTITUTION: An electronic device has a processor(114) which stores data in a memory(115) or reads/processes stored data. The electronic device is covered by an instrument(101). A luminous element(103) for emitting a light to an internal surface is included in the instrument(101). A light(109) emitted from the luminous element(103) is contacted with an internal surface(102) of the instrument(101) and the electronic device and dispersed to two-dimensional space or three-dimensional space. A partial portion of the dispersed light is collected in a light receiving element(111). An amount of a light collected to the light receiving element(111) is measured by a measuring device(112) and compared with a critical value in a comparator(113). In the case that the measured light amount is beyond tolerance, the comparator(113) outputs a predetermined signal to the processor(114). The processor(114) deletes data stored in the memory(115) in accordance with a signal from the comparator(113). The luminous element(103) is operated by a voltage being applied from an external power(107) or an internal power(106). If a level of the voltage become low or the power is stopped, a voltage comparison circuit(108) senses the variation and supplies a power from the internal power(106). A variable resistor(104) applies a power being supplied from the external power(107) or the internal power(106) to the luminous element(103) fixedly. The variable resistor(104) is controlled by a signal generated from a variable generator(105).

Abstract: The present invention relates to a security codeless telephone unit using bluetooth and communication method using the same. According to the present invention, a communication of a body of a codeless telephone in a portable device of a security codeless telephone with a portable device in a counterpart codeless telephone via a network is safely secured from a wiretapping. In order to accomplish this, the security codeless telephone unit according to the present invention includes the codeless telephone body and a portable device both of which are connected via bluetooth for allowing voice or data communication mode. Thus, if there is a request for switching a security mode from the portable device or the body, the portable device converts voice signals into encrypted digital signals using a voice codec, a vocoder and an encryption module. The portable device then transmits the encrypted digital signals to the body using the bluetooth the mode is changed from a voice communication mode to a data communication mode. Next, the body transmits the encrypted digital data to counterpart codeless telephone body and portable device via a network using a data modem. Therefore, the present invention can secure a safe communication from a wiretapping while securing the activity of a user.

Abstract translation: 本发明涉及一种使用蓝牙的安全无代码电话单元及使用其的通信方法。 根据本发明，安全无代码电话的便携式设备中的无代码电话的本体与便携式设备通过网络在对方无代码电话中的通信可以安全地免于窃听。 为了实现这一点，根据本发明的安全无编码电话单元包括无代码电话主体和便携式设备，二者都通过蓝牙连接以允许语音或数据通信模式。 因此，如果存在从便携式设备或身体切换安全模式的请求，则便携式设备使用语音编解码器，声码器和加密模块将语音信号转换为加密的数字信号。 便携式设备然后使用蓝牙将加密的数字信号发送到身体，模式从语音通信模式改变为数据通信模式。 接着，身体通过使用数据调制解调器的网络将加密的数字数据发送给对方无代码电话本体和便携式装置。 因此，本发明能够在确保用户的活动的同时确保来自窃听的安全通信。
