Abstract

본 논문에서는 1982년 D.Chaum에 의해서 개발된 은닉서명 기법을 이용한 전자화폐로부터 최근에 개발된 전자지불시스템의 기술 동향을 살펴본다. 개인의 프라이버시를 제공하기 위하여 지나친 익명성을 보장하면, 강탈, 돈세탁 등과 같은 부정적인 사용을 할 수 있으므로 신뢰기관을 연계시킴으로써, 부정 사용시 익명성을 제어할 수 있는 전자화폐시스템이 개발되었다. 또한, 이러한 신뢰기관의 익명성 제어를 위해 전자거래상에서 많은 간섭이 있다면, 직권남용을 통하여 잘못 사용될 수 있다는 점도 고려하여야 한다. 이러한 전자지불시스템에서 발생 가능한 문제점과 이를 개선하기 위한 전자지불시스템의 개발 동향을 살펴보기로 한다.
