In this paper, a zero trust-based complex biometric authentication was proposed in a passwordless environment. The linkage of FIDO 2.0 (Fast IDENTITY Online) transaction authentication platforms was designed in conjunction with metaverse. In particular, it was applied with the location information of a smart terminal according to a geomagnetic sensor, an accelerator sensor, and biometric information for multi-factor authentication(MFA). At this time, a FIDO transaction authentication platform was presented for adaptive complex authentication with user's environment through complex authentication with secondary authentication based on situational awareness such as illuminance and temperature/humidity. As a result, it is possible to authenticate secondary users based on zero trust with behavior patterns such as fingerprint recognition, iris recognition, face recognition, and voice according to the environment. In addition, it is intended to check the linkage result of the FIDO platform for complex integrated authentication and improve the authentication accuracy of the linkage platform for transaction authentication using FIDO2.0.

Despite the opinion that certificate is useless, half of the population in Korea (approx. 35 million) get an certificate, and use it for internet banking, internet shopping, stock trading, and so on. Most users store their certificates on a usb memory or smartphone, and certificates or passwords stored on such storage media can be easily attacked and used to disguise as legitimate users. Due to these security problem of certificate, a various authentication technologies has been proposed such as smartphone owner authentication using SMS, and a personal authentication using biometric authentication. However, a safe technique is not presented yet without user password, and certificate. In this paper, I proposed a method to secure certificate/private key without a user password using a combination of USIM card and smartphone's information. Even if a hacker gets the user password, the certificate, and the private key, he can not use the certificate. User do not need to remember complex password which is a combination of alphabetic / numeric / special characters, and use his certificate safely.

패스워드 기반의 사용자 인증은 비용이 적게 들고 편리성 때문에 보안상 취약점이 있어도 현재까지 광범위하게 사용되고 있다. 이러한 패스워드 기반 인증의 보안 취약성을 개선하기 위해 생체 인증을 사용하거나 다중 요소 인증기술을 적용하려는 시도는 그동안 계속되어 왔다. 하지만 기술에 따라 사용자의 편리성이 떨어지거나 광범위하게 설치하기에 비용부담이 증가하여 응용서비스에 적용하기에는 무리가 있었다. FIDO(Fast IDentity Online)는 인증 프로토콜과 인증수단을 분리하여 패스워드 없이 인증강도를 높이면서 사용자의 편리성도 높이려는 시도를 하는 기술로 패스워드의 문제를 극복하여 스마트 모바일 환경에 적합한 인증기술로 활용될 수 있다.
