초록

개인식별번호(personal identification number: PIN)는 숫자로 이루어진 짧은 패스워드로서, 은행 ATM, 디지털 도어락, 스마트 디바이스 등에서 사용자 인증을 위해 널리 쓰이고 있다. PIN을 입력하기 위한 전통적인 키패드 방식의 인터페이스는 엿보기나 녹화 등의 공격에 취약하며, 이를 방지하기 위해 다양한 PIN 입력 방식들이 제안된 바 있다. 그러나, 잘못 설계된 PIN 입력 방식은 무작위 대입 공격 등 다른 공격에 대한 안전성이나 사용자 편의성을 떨어뜨릴 수 있다. 이 논문에서는 특히 스마트 디바이스 상에서 PIN을 안전하게 입력하기 위한 다양한 방식들을 조사하고 이들의 특성을 분석함으로써 안전하고 편리한 PIN 입력 방식의 설계를 위한 방향을 제시한다.
