통신시스템의 디피-헬만형 키 분배방법Diffie-Hellman type key distribution method of communication system

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명이 적용되는 통신시스템의 구성도,1 is a configuration diagram of a communication system to which the present invention is applied;

제2도는 본 발명에 의한 디피-헬만형 키 분배방법의 흐름도.2 is a flowchart of a Diffie-Hellman type key distribution method according to the present invention.

Claims (1)

암호통신 매체인 제1 및 제2터미널(i, j)(2.3), 및 상기 제1 및 제2터미널(i, j)(2,3)간에 정보를 교환하기 위한 통신로(1)를 포함하여 구성되는 통신시스템의 암호화 기능을 제공하는 디피-헬만(Diffie-Hellman형 키 분배방법에 있어서, 상기 제1 및 제2터미널(i,j)(2,3)이 상대방의 공개키(Yi,Yj)와 자신의 비밀키(Si,Sj)를 이용하여 상기 제1 및 제2터미널(i,j)(2,3)간의 비밀공유키(M)를 계산하는 제1단계(10), 상기 제1터미널(i)(2)이 랜덤수(Ri)를 생성하여 상기 제2터미널(j)(3)로 전송하고, 상기 제2터미널(0)(3)이 랜덤수(Rj)를 생성하여 상기 제1터미널(i)(3)로 전송하는 제2단계(20), 및 상기 제1및 제2터미널(i,j)(2,3)이 상기 비밀공유키(M)와 랜덤스(Ri,Rj)를 이용하여 세션키(Ks)를 계산하여 공유하는 제3단계(30)에 의해 수행되는 것을 특징으로 하는 디피-헬만(Diffie-Hellman) 형 키 분배방법.First and second terminals (i, j) (2.3), which are cryptographic communication media, and a communication path (1) for exchanging information between the first and second terminals (i, j) (2, 3). In a Diffie-Hellman type key distribution method for providing an encryption function of a communication system configured by the communication system, the first and second terminals (i, j) (2, 3) are the public key Yi, A first step (10) of calculating a secret shared key (M) between the first and second terminals (i, j) (2, 3) using Yj) and its secret keys (Si, Sj), The first terminal (i) (2) generates a random number Ri and transmits it to the second terminal (j) (3), and the second terminal (0) (3) generates a random number (Rj) The second step 20 of transmitting to the first terminal (i) (3) and the first and second terminals (i, j) (2, 3) are randomized with the secret shared key (M) Diffie-Hellman type key distribution room, which is performed by the third step 30 of calculating and sharing the session key Ks using (Ri, Rj). . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
