  • This paper propose DA-UDC(Double Authentication User, Device, Cross) Module which solves the cost problem and the appropriation of Certificate using User Authentication, Device Authentication and Cross Authentication with OTA(One Time Authentication) Key, and which is designed not to subscribe to the service of Home network business. Home Server transmits its public key which is needed to create OTA to the user which passed the first step of authentication which verifies User ID, Device ID and Session Key. And it performs the second step of authentication process which verifies the OTA key created by a user. Whenever the OTA key of DA-UDC module is generated, the key is designed to be changed. Therefore, DA-UDC Module prevents the exposure of User and Device ID by performing the two steps of authentication and enhances the authentication security of Home Network from malicious user with OTA key. Also, DA-UDC Module is faster than the existing authentication system in processing speed because it performs authentication calculation only once. Though DA-UDC Module increases data traffic slightly because of the extra authentication key, it enhances the security more than the existing technique.

  • The purpose of this paper is to improve the authentication method for IP camera user authentication. Since existing authentication uses knowledge-based authentication method, if ID and PW are exposed to attack by attacker, IP camera becomes defenseless from attacker. The attacker can access the IP Camera and acquire and distribute real time video and voice, which can be exploited as a second crime, and there is a fear of a secret leak when a secret facility is installed. In order to compensate for this vulnerability, this paper proposes a DUI authentication method that identifies and registers a device using DUI (Device Unique Identifier), blocks access to unauthorized devices by subordinating the device to the IP Camera and authenticates only authorized devices.

  • A variety of services for mobile payments by the activation of FinTech have been developed. Various payment methods were developed, and an authentication method was developed to improve the reliability of the payment. On the other hand, when mobile easy payment services are used, they have weak security because the authentication by phone number. Therefore, this paper proposes a technique for increasing the reliability of the authentication process using the unique device ID of the mobile device to improve the authentication process based on the telephone number. The core research contents are the architecture and process for the authentication of mobile payments based on the mobile device ID. The mobile payment architecture consists of a mobile device, authentication service, and mobile payment application. The mobile device consists of mobile device ID and phone number, and the authentication server consists of authentication module and encryption module. The mobile payment service consists of a pre-authentication module and decryption module. The process of mobile payment service is processed by the encrypted authentication information (device ID, phone number, and authentication number) among mobile devices, authentication server, and mobile payment application. The mobile device sends the telephone number and the device ID to the authentication server and the authentication server authenticates the user through an authentication process and encryption process. The mobile payment application performs the pre-authentication process by decrypting the received authentication number. This paper reports a difference that can prevent the risk of leakage of the authentication number in existing payment services through the authentication process of the authentication server and the pre-authentication process of the mobile payment service of this paper.

  • ogy is being used in many fields, such as smart farms, smart oceans, smart homes, and smart energy. Various IoT terminals are used for these IoT services. Here, IoT devices are physically installed in various places. A malicious attacker can access the IoT service using an unauthorized IoT device, access unauthorized important information, and then modify it. In this study, to solve these problems, we propose an authentication system for IoT devices used in IoT services. The IoT device authentication system proposed in this study consists of an authentication module mounted on the IoT device and an authentication module of the IoT server. If the IoT device authentication system proposed in this study is used, only authorized IoT devices can access the service and access of unauthorized IoT devices can be denied. Since this study proposes only the basic IoT device authentication mechanism, additional research on additional IoT device authentication functions according to the security strength is required.IoT technol

  • IoT is being used in a lot of industry domain such as smart home, smart ocean, smart energy, and smart farm, as well as legacy information services. For a server, an IoT device using the same protocol is a trusted object. Therefore, a malicious attacker can use an unauthorized IoT device to access IoT-based information services and access unauthorized important information, and then modify or extract it to the outside. In this study, to improve these problems, we propose an IoT device authentication system used in IoT-based information service. The IoT device authentication system proposed in this study applies identifier-based authentication such as MAC address. If the IoT device authentication function proposed in this study is used, only the authenticated IoT device can access the server. Since this study applies a method of terminating the session of an unauthorized IoT device, additional research on the access deny method, which is a more secure authentication method, is needed.

  • In this paper, we described about the home device authentication framework, certificate issuing process and home device authentication method. since the home device authentication scheme of the public key infrastructure would be more needed as the number of home device can participate in the home network increased, we described about the home device authentication system of the public key infrastructure. Moreover, we described about the construction method of CA adminstration interface for convenient CA administration.

  • As the distribution rate of smart device increases, users of smartwork are increasingly able to work without constraints imposed by time and space. However, there are many security threats in smartwork environment. Security threats is illegal information for an unauthenticated device. Especially, smartwork environment is approach to users. Therefore, there are other matters concerning justifiable user and device authentication. However, the studies of smartwork are still in early stage of development, and the studies of user and device authentication also not enough to apply smartwork environment. In this paper, we proposed USIM based user and device authentication scheme in the smartwork environment.

  • 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.
