Abstract: Provided is a method of transmitting security information of a single-bit analog-to-digital converter (ADC) wiretap channel. In the method of transmitting the security information of the single-bit ADC channel, a transmitting terminal adds additive noise to a transmission signal and transmits the transmission signal, and a receiving terminal and a wiretap terminal which each include a single-bit ADC receive the transmission signal, wherein received information is processed so as not to be determined by the wiretap terminal. When intensity of additive noise of the receiving terminal is less than that of additive noise of the wiretap terminal, a binary phase-shift keying (BPSK) distribution is used, and when the intensity of the additive noise of the receiving terminal is greater than that of the additive noise of the wiretap terminal, a codebook is designed using an asymmetric BPSK distribution in which both of two message points have a positive value.

Abstract: The present invention relates to a patch type thermometer containing a polymer that can be phase changed from a solid phase to a liquid phase. The patch type thermometer provided in an aspect of the present invention demonstrates high precision since it does not include conductive particles which have been a reason of disadvantage of the conventional temperature sensor, and has the effect of no temperature deviation in repeated temperature measurements because it is composed of such a single polymer material that is phase changed in a specific temperature range so that the polymer material can be reversibly changed in the volume and shape.
