Abstract

In this paper, we present multi-channel authentication based security card design. Since this security card is written on the transparent paper, security information is extracted by overlaying the card with smartphone screen. This method removes the limitations of physical layout in previous security card and improves the security level. Furthermore, our security card is secure when our card is exposed to malicious users.

본 논문에서는 다중 채널 보안카드 설계 기법을 제공한다. 해당 보안 카드는 투명하게 제작되어 스마트폰의 화면과 합쳐서 나타나는 정보를 통해 비밀값을 도출하게 된다. 이는 기존 보안카드가 가지는 레이아웃의 물리적인 한계를 제거하여 보안카드가 가지는 복잡도를 향상시켰으며 1채널 보안카드의 단점인 물리적 노출에 대한 취약점을 다중 채널로 확장하여 한 번의 물리적 보안카드의 노출이 모든 비밀 정보의 노출로 연결되는 문제점도 해결하였다.
