Last time when we introduced a DHCP proxy agent through our previous blog post dated in September 1. 2013, we mentioned that this DHCP proxy agent can offer the benefits of enhanced security. So, we will look into these security-related functions in more detail today. As shown in the figure below, if there is a DHCP proxy agent in a network, all DHCP messages (used in IP address allocation...

All wireless telecommunication networks (e.g. Wi-Fi, WiBro and LTE provide “user authentication” and “security over radio link (integrity check (protection/verification) and ciphering (or encryption))” features. User authentication is required for network operators to ensure that only those who subscribe to them (i.e. paid subscribers) can access their networks. In wir...

지난 시간에는 LTE 망과 Wi-Fi 망 간에 연동 구조에 대해 살펴 보았는데요. 오늘은 인증(Authentication)과 보안(Security)에 대해서 알아 보도록 하겠습니다. 이동 통신 기술에서의 인증과 보안(암호화/무결성 보호) 기술은 수많은 Key들과 알고리즘으로 인해 이해하기 참 쉽지 않은 분야라고 생각합니다. 오늘 설명 드릴 내용은 그런 복잡한 얘기는 제하고 쉽게 개념 위주로 설명 드리고자 합니다. 1. 인증 (Authentication) ■ 인증 정보는 누가 가지고 있나? UE는 USIM에 인증 정보가 들어 있고, 망은 HSS에 그 정보가 저장(Provisioning)되어 있습니다. 물론 UE 별로(IMSI 별로) 서로 다른 인증 정보를 가지고...

2011.12.23일자 Netmanias Blog을 통해 DHCP Proxy Agent에 대해서 소개 드리면서 이 DHCP Proxy Agent를 이용하면 "보안"이 좋다고 말씀드린바 있습니다. 오늘은 그 "보안" 기능이 뭔지 설명드리겠습니다. 아래 그림과 같이 유선망에 DHCP Proxy Agent가 위치하게 되면, 모든 DHCP 메시지(IP address Allocation, IP address Renewal, IP address Release)는 이 DHCP Proxy Agent를 통과(DHCP Proxy Agent가 수신)하게 되고, 이를 통해 DHCP Proxy Agent는 DHCP를 통해 IP 주소를 할당받지 않은 가입자(고정 IP 가입자)의 트래픽을 차단할 수 있습니다. 그 차단 방...

오늘은 국내 통신 3사의 Wi-Fi Hotspot에서의 웹기반 인증 방식에 대해서 설명드리겠습니다. 여기서 소개하는 웹인증 방식은 통신 3사의 특정 자료를 기반으로 하지 않고 간단한 테스트에 몇가지 추론을 첨가하여 작성하였으므로, 약간의 오류가 있을 수 있음을 먼저 알려 드립니다. 현재 국내 통신 사업자는 전국에 Wi-Fi Hotspot을 구축해 놓은 상태이며(지금도 계속 늘려가고 있지요) 어떤 SSID(Wi-Fi 서비스 이름)는 자물쇠 모양이 있어 802.1x 기반으로 인증을 받아야 인터넷 액세스가 되는 반면 어떤 SSID는 자물쇠 모양이 없는 즉, 802.1x 기반의 인증이 아닌 웹기반(웹서버에 접속하여 ID/PW 입력)으로 인증을 수행합니다. (단말 MAC 기반으로 인증을 하는 경우도 있는...
