FIDO(Fast IDentity Online) technology is expanding very rapidly which can replace traditional password-based authentication with biometrics technology[1,7]. FIDO provides convenient authentication with biometrics technology and secure key management with smart card technology, but it does not provide user identification, thus traditional user identification technology should be used before a FIDO device is registered to a FIDO server. K-FIDO[3] is an approach to implement FIDO and certificate-based authentication technology into a single device that user can utilize certificate-based authentication in initial registration of FIDO device to FIDO server. It is expected that very shortly users will own and use multiple K-FIDO devices. If we consider the traditional approach of copying single certificate to multiple devices or issuing independent certificate to each device, there will be many complex problems. In this paper we propose more secure and convenient key management technology in multiple K-FIDO device scenario using self-extended certification[4].

In this paper, we describe a FIDO universal authentication system based on a Blockchain that can share the user's FIDO authentication information between the application services of multiple domains without the use of a server. In addition we provide a method to query the FIDO authentication information of the user recorded in the Blockchain using only the user's service ID. Therefore, even if the user executes the FIDO registration process only once, the user can use the FIDO authentication service of another application service without repeating an additional FIDO registration procedure, and the service provider can securely share and utilize the FIDO authentication information of the user without the use of a trusted third party, thereby lowering the deployment and maintenance costs of the FIDO server.

There are three standards for FIDO1 authentication technology: Universal Second Factor (U2F), Universal Authentication Framework (UAF), and Client to Authenticator Protocols (CTAP). FIDO2 refers to the WebAuthn standard established by W3C for the creation and use of a certificate in a web application that complements the existing CTAP. In Korea, the FIDO certified market is dominated by UAF, which deals with standards for smartphone (Android, iOS) apps owned by the majority of the people. As the market requires certification through FIDO on PCs, FIDO Alliance and W3C established standards that can be certified on the platform-independent Web and published 『Web Authentication: An API for Accessing Public Key Credentials Level 1』 on March 4, 2019. Most PC do not contain biometrics, so they are not being utilized contrary to expectations. In this paper, we intend to present a model that allows login in PC environment through biometric recognition of smartphone and FIDO UAF authentication. We propose a model in which a user requests login from a PC and performs FIDO authentication on a smartphone, and authentication is completed on the PC without any other user's additional gesture.

Recently, Biometrics is being magnified than ID or password about user authentication. However, unlike a PIN, password, and personal information there is no way to modify the exposure if it is exposed and used illegally. As FIDO(Fast IDentity Online) than existing server storing method, It stores a user's biometric information to the user device. And the user device authentication using the user's biometric information, the user equipment has been used a method to notify only the authentication result to the server FIDO. However, FIDO has no mutual authentication between the user device and the FIDO server. We use a Certificate Authority in order to mutually authenticate the user and the FIDO server. Thereby, we propose a more reliable method and compared this paper with existed methods about security analysis.

국내 인증기술은 패스워드를 시작으로 X.509 인증서 기반의 공인인증 기술로 발전되어 왔고 현재는 패스워드의 보안 취약성을 개선하기 위해 개발된 FIDO 기술로 전환되는 과정에 있다. FIDO는 바이오 인증 기술뿐만 아니라 다중 인증 기술도 지원하는 범용인증기술로 FIDO 인증 서버를 한번만 설치하면 서비스 제공자의 요구사항에 따라 다양한 인증방식을 서버 변경 없이 수용할 수 있다는 장점을 가지고 있어, 금융, 결제 등 다양한 분야에 급속하게 확산되고 있다. 본 고에서는 범용인증기술인 FIDO 1.0 기술을 설명하고 최근에 표준화를 진행하고 있는 FIDO 2.0 기술에 대한 소개 및 FIDO 1.0 기술과의 차이점을 기술하여 FIDO 2.0이 가지는 여러 의미를 분석하여 향후 인증기술에 대한 전망을 제시한다.

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.

Fast IDentity Online(FIDO) supports biometric authentications in an online environment without transmitting biometric templates over the network. For a given FIDO client, the "Fuzzy Vault" securely stores biometric templates, houses additional biometric templates, and unlocks private keys via biometrics. The Fuzzy Vault has been extensively researched and some vulnerabilities have been discovered, such as brute force, correlation, and key inversions attacks. In this paper, we propose a simple fingerprint Fuzzy Vault for FIDO clients. By using the FIDO feature, a simple minutiae alignment, and point-to-point matching, our Fuzzy Vault provides a secure algorithm to combat a variety of attacks, such as brute force, correlation, and key inversions. Using a case study, we verified our Fuzzy Vault by using a publicly available fingerprint database. The results of our experiments show that the Genuine Acceptance Rate and the False Acceptance Rate range from 48.89% to 80% and from 0.02% to 0%, respectively. In addition, our Fuzzy Vault, compared to existing similar technologies, needed fewer attempts.
