Abstract: PURPOSE: A method for generating an electromagnetic wave using software is provided to generate electromagnetic wave by controlling noise generated in a bus connecting a CPU and a memory. CONSTITUTION: An electromagnetic wave pattern data is set in consideration of the number of lines and transmission characteristics of a bus interlinking a CPU and a main memory'(S311). The electromagnetic wave pattern data is saved in the register of the above CPU(S312). When electromagnetic wave pattern data is recorded, a main memory is set(S313). The electromagnetic wave pattern data is transmitted through all lines of the bus to the fixed address of the main memory(S314). The electromagnetic wave corresponding to electromagnetic wave pattern data is generated in a process that electromagnetic wave pattern data is transmitted through the bus to the main memory.

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).
