Abstract

본 발명은 디지틀 이동통신 시스템의 인증기능 중 인증키를 생성하는 방식에 관한 것으로, 특정소수를 선정하여 상기 특정소수 이하의 숫자를 사용한 숫자배열 리스트를 구성하는 제 1 과정과, 임의의 현재 시간을 소정비트의 초기화 난수로 설정한후 상기 특정소수로 나눈 값을 제 1 과정에서 구성된 숫자배열 리스트중 대응하는 숫자를 산출하는 제 2 과정과, 상기 제 2 과정에서 산출되어진 숫자를 상기 초기화 난수와 합산하여 인증키 형성을 위한 데이타로 저장하는 제 3 과정과, 상기 제 3 과정에서 저장되어진 데이타의 길이에 대응하는 잉여류들의 집합을 산출한 후 하나의 순환군을 생성하는 제 4 과정과, 상기 제 4 과정에서 생성된 순환군에 속하지 않은 원소들은 무작위로 섞어서 재 배열한 후 배열순서에 따라 순환 고리를 형성하는 제 5 과정 및 상기 제 4 과정과 제 5과정을 반복수행하여 매순간 형성되는 순환고리를 인증키로 사용하는 제 6 과정을 포함하는 것을 특징으로 하는 디지틀 이동통신망의 인증 센터에 사용되는 인증키 생성방법을 제공하면, 키생성에 대한 계산량의 감소로 생성시간을 줄일 수 있고, 계산에 따른 인증 센터 시스템의 부하를 경감함으로써, 호처리에 할당할 수 있는 프로세서 사용시간을 늘여주어 인증센터의 전체적인 성능 향상을 기대할 수 있다.The present invention relates to a method of generating an authentication key among the authentication functions of a digital mobile communication system. A second step of calculating a corresponding number from the list of numbers arranged in the first step after setting the initialization random number of a predetermined bit and adding the number calculated in the second step with the initialization random number; A third process of storing the data as data for forming an authentication key, a fourth process of calculating a set of surplus flows corresponding to the length of the data stored in the third process, and then generating one cycle group; A fifth process of forming a circular ring according to the arrangement order after the elements which do not belong to the circulation group generated in step 4 are randomly mixed and rearranged; When the authentication key generation method used in the authentication center of the digital mobile communication network comprising a sixth process of repeating the fourth process and the fifth process using a circular ring formed every time as an authentication key, the key By reducing the computational amount for generation, the generation time can be reduced, and by reducing the load on the authentication center system according to the calculation, it is possible to increase the processor usage time that can be allocated to call processing, thereby improving the overall performance of the authentication center.

이러한 장점은 많은 가입자를 수용하게될 PCS, UPT 등의 서비스에도 적합하다는 것이다.This advantage is also suitable for services such as PCS and UPT, which will accommodate many subscribers.
