최근 홈, 오피스 및 핫스팟 영역에서 초고속 멀티미디어의 서비스 수요가 많아짐에 따라 고속의 안정적인 무선랜에 대한 수요도 증가하고 있다. Access Point를 이용한 네트워크를 하는 무선랜은 네트워크에 접근하는 사용자에 대한 인증 프로토콜을 통한 보안이 필요로 하며, 무선랜의 특성상 단말의 이동으로 인해, 핸드오프 시마다 반복되는 사용자 인증은 또 다른 문제를 야기한다. 또, 차세대 인터넷 프로토콜 IPv6는 현재의 주소체계인 IPv4가 인터넷에 접속된 컴퓨터 수의 기하급수적으로 증가로 인해 빠른 속도로 고갈되는 상황에서의 대안이다. 따라서 본 논문에서는 이동성을 고려하여 무선랜 환경에서 안전하게 사용자를 인증하고 서비스를 제공하기 위한 패스워드 기반의 사용자 인증 프로토콜을 제안한다. 또한 본 논문에서 제안한 프로토콜을 차세대 주소체계인 IPv6 환경을 바탕으로 구현하였고, 제안한 프로토콜에 대한 다양한 공격으로부터의 안전성을 분석 하였다.

A renal infarct is too rare a disease for early diagnosis and treatment. Furthermore, it presents nonspecific symptoms in many patients. Cardiac diseases such as valvular heart disease and arterial fibrillation are the most common causes of renal infarct. Vascular disease such as renal artery dissection or aortic dissection, trauma, inflammation, vasculitis, malignancy and antiphospholipid syndrome have been also known as possible causes of renal infarct. In acute pancreatitis, adjacent vessels can be involved, and were reported to induce splenic infarction, portal vein thrombosis and superior mesenteric vein thrombosis etc. However, the renal infarct from renal artery involvement in acute pancreatitis has not yet been reported. In our case, a 46 year old male patient had an abdominal trauma due to an in-car accident to develop a rupture of pancreatic tail. The progression of acute pancreatitis caused the inflammation of left renal artery, leading to renal artery obstruction. We report a case of renal infarct developed in acute pancreatitis.
