웹 기반의 전자ID지갑을 모바일 환경에서 활용하게 되면 오프라인에서 각종 인증 및 지불 등이 모바일 전자ID지갑을 통해 가능하게 된다. 모바일 전자ID지갑이 오프라인에서 활용되려면 근거리 무선망을 통한 통신이 이루어져야 하는데, 이를 위해서는 각 사업자별로 동일한 방식으로 무선 통신이 이루어져야 모바일 전자ID지갑의 상호운용성을 보장할 수 있다. 이러한 근거리 무선통신 기술로 NFC(Near Field Communication)가 세계 표준으로 지정되어 기술 개발이 이루어지고 있다. 본 논문에서는 전자ID지갑의 역할을 오프라인으로 확대시킬 수 있는 NFC 기술과 이와 관련된 보안 알고리즘, NFC와 USIM 인터페이스에 대해 연구한다.

Most recent trend reveals broader state of provision of NFC service as NFC technology was applied on smartphones which has become core communication tools by providing integrated services such as payment, medical, and personal authentication. Moreover, with integration of original service and NFC technology, new service providers now can handle personal information of original service or can handle other personal information with transition of previous service provider to NFC service provider. Considering current state of security industry along with NFC technology and service, we would like to analyze current stage of security threats and plan the counter strategies to create NFC service structure.

In this paper, smart door-lock system to access public facilities will be proposed. An existed door-lock system using physical door-lock, NFC Tag, and RFID could be replaced by our proposed system. Automatic access control management system with security authentication module enables the worker to access public facilities efficiently.

Recently, an application business model was proposed to implement an M-coupon system using the NFC-based mobile devices. In this paper, the security requirements were surveyed for a secure M-coupon system and to analyze the threats on the existing NFC-based M-coupon protocols. After considering the implementation efficiency and security, this paper presents a novel M-coupon protocol based on the Diffie-Hellman key agreement scheme. This protocol can be an alternative to solve the security problems related to the PKI (Public Key Infrastructure) and secret key distribution. Furthermore, this M-coupon protocol is designed to provide user authentication and counteract the relay attack.

Recently, NFC technology of short-range wireless communication using a smart phone to perform personal authentication with the electronic payment has been in the spotlight in various fields. However, the security associated with the personal information and the location information is vulnerable because it is easily fused with the existing mobile services and devices. In this paper, we propose a model for NFC payments help protect personal information and location information of NFC payment systems and services in various fields. Proposed model uses tag-based services in order to protect personal information and position information. The proposed model using the tag-based services is the place to check the various features available information in a simple Tag that can be easily accessed.

Wireless communication technology such as NFC and RFID makes the data transfer between devices much easier. Instead of the irksome typing of passwords, users are able to simply authenticate themselves with their smart cards or smartphones. Relay attack, however, threatens the security of token-based, something-you-have authentication recently. It efficiently attacks the authentication system even if the system has secure channels, and moreover it is easy to deploy. Distance bounding or localization of two devices has been proposed to detect relay attacks. We describe the disadvantages and weakness of existing methods and propose a new way to detect relay attacks by recording a background noise.
