CDMA2000, 무선랜 등의 무선 네트웍 접속 환경이 좋아지고, 무선 기기의 능력 역시 예전에 비하여 비약적으로 발전하면서 핸드폰이나 PDA와 같은 단말을 이용한 무선인터넷의 이용이 점점 늘어가고 있다. ADSL, 케이블 모뎀 등을 이용한 인터넷 환경이 발달하면서 인터넷을 이용한 전자상거래의 수요가 폭발적으로 증가했듯, 이제는 무선인터넷을 이용한 전자상거래의 수요가 매우 커질 것으로 보이며, 이동통신 업체와 금융권 등 무선 전자상거래에 관련이 있는 다양한 분야의 업체들이 이 부분에 주목을 하고 있다. 그러나 안전성과 편의성이 지원되지 않는 전자상거래 시스템은 아무런 의미가 없으며, 이는 곧, 무선 전자상거래를 위해서는 이를 위한 정보보호 기반 기술과 보안 프로토콜이 선행되어야 함을 뜻한다. 본 고에서는 무선전자상거래를 위한 기반 기술 및 프로토콜에 대해 살펴보고 국내외 동향을 알아보고자 한다.
