- W2047442679 abstract "E-비즈니스의 발전으로 온라인 서비스가 증가하면서, 금융이나 게임업체 등에서 정적 패스워드에 대한 취약성을 보완하기 위해서 OTP(One-Time Password)를 사용하고 있다. 기존의 OTP는 전용토큰을 이용하는데, 토큰을 이용한 OTP 기술은 항상 전용토큰을 소지하여야 한다. 이러한 단점을 보완하기위해 스마트폰과 같은 모바일 기기를 이용한 모바일 OTP를 제안한다. 본 논문에서 제안하는 모바일 OTP 기법은 범용적으로 사용되고 있는 해쉬함수를 이용한 S/KEY OTP 기법의 해쉬 충돌성에 대한 문제를 해결하기 위해 Pairing 기법을 이용한 비선형적 함수를 이용하여 OTP를 생성한다. 제안한 Pairing 기반의 비선형 함수를 이용한 모바일 OTP 기법은 기존의 해쉬충돌성을 보완할 수 있으며, 금융업체 및 다양한 서비스에서 보안안전성을 강화하기 위해 폭넓게 응용될 수 있을 것이다. While increasing online services with developing e-businesses, finance, game companies and others have employed OTP(One-Time Password) to overcome vulnerabilities of static passwords. Existing OTP technology has inconvenience that customers always possess reserved token since requiring the token to generate OTP. In order to supplement the issue we propose mobile OTP generated by mobile devices such as smart phones. Our mobile OTP scheme generates OTP by using a non-linear function based on pairing to eject the collision problem of S/Key scheme universally used to design OTP schemes. Our scheme based on a non-linear function over pairing can complements the collision problem and widely applied to finance and various services to increase security level of the services." @default.
