Abstract

본 발명은 단리의 마이크로 스위치와 금속커버체에 의한 간단한 구성으로서 외부에 있는 메모리내의 프로그램을 보호하기 위한 소프트웨어 해독방지장치에 관한 것이다.The present invention relates to a software decryption device for protecting a program in an external memory as a simple constitution by an isolated micro switch and a metal cover body.

종래 장치는 소프트웨어가 주변환경에 개방(Open)되어 있기 때문에 이른바 디스어셈블러(Disassembler)를 이용하여 프로그램을 분석하는 형태로서, 소프트웨어 크기가 소형인 경우에는 단일칩 마이크로 컴퓨터에 내장한 후, 점차적으로 다기능화 되어가는 추세에 따라 소프트웨어 크기도 점차 대형화되고 프로그램도 다양화해짐에 따라 단일칩화가 어려운 문제점이 있었다.The conventional apparatus is a type of analyzing a program using a so-called disassembler because the software is open to the surrounding environment. When the software is small in size, it is embedded in a single-chip microcomputer and gradually becomes multifunctional There is a problem that the size of the software gradually becomes larger and the programs become diversified, making it difficult to make a single chip.

따라서, 본 발명은 기존의 회로에 마이크로 스위치를 부설하여 불특정인이 프로그램을 분석하기 위해 제품의 커버를 개방하거나 회로에 손을 데면 마이크로 스위치가 온(ON)되어 프로그램이 순간적으로 소멸되도록 하는 소프트웨어 해독방지장치를 제공코자 하는 것이다.Therefore, in the present invention, when a micro switch is installed in an existing circuit to open a cover of a product or analyze a program to unspecified, a micro switch is turned on when a user touches a circuit, Prevention device.
