Abstract
본 발명은 마이크로 컴퓨터의 보안 방법 및 장치에 관한 것으로서, 특히 마이크로 컴퓨터의 데이타 보호를 위한 보안 방법 및 장치에 관한 것이다.The present invention relates to a security method and apparatus for a microcomputer, and more particularly, to a security method and apparatus for data protection of a microcomputer.
본 발명의 목적을 위하여 클럭 카운터부의 카운트된 값과 상기 마이크로 컴퓨터 시스템 고유의 값을 비교하여 일치하면 동기 클럭을 출력하는 동기 클럭 검출부, 키이 코드부의 키이 데이타를 확인하는 고유의 시간이 동기 클럭 검출부의 동기 클럭 갯수를 단위로 하여 코드화되어 있는 클럭 코드부, 동기 클럭 검출부의 동기 클럭의 발생 횟수가 클럭 코드부에 정해준 값과 일치 할 경우 상기 데이타 버퍼부의 외부 데이타와 상기 키이 코드부의 키이 데이타를 비교하고, 상기 각각의 데이타가 일치하면 상기 마이크로 컴퓨터 메모리의 읽기와 쓰기가 허용되는 키이 코드 검출부로 구성되는 것을 특징으로 한다.For the purposes of the present invention, if the counted value of the clock counter unit and the unique value of the microcomputer system are compared and matched, a synchronous clock detector for outputting a synchronous clock, and a unique time for checking key data of the key code unit is a synchronous clock detector. When the number of occurrences of the synchronous clock of the clock code unit and the synchronous clock detection unit coded by the number of synchronous clock units coincides with the value specified in the clock code unit, the external data of the data buffer unit and the key data of the key code unit are compared. And a key detection unit configured to allow reading and writing of the microcomputer memory if the respective data coincide with each other.
상술한 바와 같이 본 발명에 의하면, 마이크로 컴퓨터의 메모리를 액세스 할 수 있는 키이 코드를 특정 시간에만 검출되게 함으로서 시스템의 보안을 강화 할 수 있다.As described above, according to the present invention, the security of the system can be enhanced by allowing the key code that can access the memory of the microcomputer to be detected only at a specific time.
