  • Pointcheval과 Zimmer는 2008년에, 사용자의 비밀 키, 패스워드, 생체정보를 모두 이용한 다중 인증 요소 기반 키 교환 프로토콜을 제안하였다. 하지만, Hao와 Clarke는, 공격자가 한 개의 인증요소 (패스워드) 를 알고 있다고 가정 했을 때 이를 이용해서 나머지 두 개의 인증요소인 사용자의 비밀 키와 생체정보를 모두 알 수 있는 안전성 결함이 있음을 보였다. 하지만, Hao와 Clarke은 프로토콜 설계의 구조적인 결함 및 복잡성을 이유로 그에 대한 해결책을 제안하지 못하고 남겨 두었다. 본 논문에서는 Hao와 Clarke이 제시한 공격을 효율적으로 방어할 수 있는 대응방안을 제시하고 안전성을 논의한다.

  • In this paper, a secure multilevel quadrature amplitude modulation (MQAM) scheme is proposed for the physical layer security (PLS) of the wireless communications. In the proposed scheme, each transmitted symbol's signal constellation (SC) is hopping with the control of two unique factors: amplitude distortion (AD) factor and phase hopping (PH) factor. With unknown the two factors, the eavesdropper cannot extract effective information from the received signal. We first introduce a security metric, referred to as secrecy gain, and drive a lower bound on the gain that the secrecy capacity can be improved. Then, we investigate the relationship among the secrecy gain, the signal to noise power ratios (SNRs) of the main and wiretap channels, and the secrecy capacity. Next, we analyze the security of the proposed scheme, and the results indicate that the secrecy capacity is improved by our scheme. Specifically, a positive secrecy capacity is always obtained, whether the quality of the main channel is better than that of the wiretap channel or not. Finally, the numerical results are provided to prove the analytical work, which further suggests the security of the proposed scheme.

  • 내부에 있는 정보를 보호하기 위한 노력들 중 하나인 네트워크 접근통제 시스템의 적용은 내부 사용자들의 효과적 제어 및 자동적인 네트워크 관리와 보안을 가능하게 한다. 그러나 이미 허가된 PC 또는 모바일 기기로 위장하거나 자리를 비운 사용자의 인가된 시스템을 이용하여 내부 네트워크에 접속할 수 있는 문제점이 있다. 또한 허가된 PC 또는 모바일 기기의 악성코드 감염으로 인해 사용자가 직접 사용하는 시간 이외에도 동작하여 비의도적인 정보유출 및 내부 네트워크 공격 등이 발생할 수 있다. 따라서 내부 네트워크에 접속을 허가 받은 이가 인가된 장비를 이용하여 접근정책에 따른 통신을 수행하고 있는지를 확인해야 한다. 이를 위해 본 연구에서는 RFID 출입통제시스템과 연동한 네트워크 이중 접근통제 시스템을 제안한다. 제안된 시스템은 내부 네트워크 접속 시 이중인증을 수행함으로써 허가된 사용자가 인가된 장비를 이용하여 통신을 수행하는 환경을 제공한다.

  • Many security systems rely solely on solutions based on Artificial Intelligence, which are weak in nature. These security solutions can be easily manipulated by malicious users who can gain unlawful access. Some security systems suggest using fingerprint-based solutions, but they can be easily deceived by copying fingerprints with clay. Image-based security is undoubtedly easy to manipulate, but it is also a solution that does not require any special training on the part of the user. In this paper, we propose a multi-factor security framework that operates in a three-step process to authenticate the user. The motivation of the research lies in utilizing commonly available and inexpensive devices such as onsite CCTV cameras and smartphone camera and providing fully secure user authentication. We have used technologies such as Argon2 for hashing image features and physically unclonable identification for secure device-server communication. We also discuss the methodological workflow of the proposed multi-factor authentication framework. In addition, we present the service scenario of the proposed model. Finally, we analyze qualitatively the proposed model and compare it with state-of-the-art methods to evaluate the usability of the model in real-world applications.

  • Physical layer security (PLS) can improve the security of both terrestrial and nonterrestrial wireless communication networks. This study proposes a simplified framework for nonterrestrial cyclic prefixed orthogonal variable spreading factor (OVSF)-encoded multiple-input and multiple-output nonorthogonal multiple access (NOMA) systems to ensure complete network security. Various useful methods are implemented, where both improved sine map and multiple parameter-weighted-type fractional Fourier transform encryption schemes are combined to investigate the effects of hybrid PLS. In addition, OVSF coding with power domain NOMA for multi-user interference reduction and peak-toaverage power ratio (PAPR) reduction is introduced. The performance of $\frac{1}{2}$-rated convolutional, turbo, and repeat and accumulate channel coding with regularized zero-forcing signal detection for forward error correction and improved bit error rate (BER) are also investigated. Simulation results ratify the pertinence of the proposed system in terms of PLS and BER performance improvement with reasonable PAPR.

  • 핀테크 환경에서 스마트 폰을 이용한 금융거래가 활발하게 이루어지고 있다. 안전한 금융거래를 위해 사용자 인증 기술이 필수적이다. 기존 보안 키패드를 통한 PIN 인증은 입력 편리성이 좋지만, 보안성이 떨어지고 취약점이 존재한다. 생체인증 기법은 보안성이 안전하지만 오탐 및 미탐 인증 가능성이 있다. 이를 보완하기 위해 2-factor 인증을 사용한다. 본 논문에서는 생체인증 기법을 적용한 PIN 입력을 통해 편리성과 보안성을 높일 수 있는 1.5-factor 인증을 제안하고자 한다. 지문인증의 안정성과 2~4번의 PIN 입력을 통해 편리성을 제공하여 안전한 금융거래가 가능하다. 제안기법은 PIN 입력 시 생체인증을 동시에 수행하므로 PIN 입력할 때 터치하는 영역에 지문인식을 적용하는 방식이다. 보안이 요구되는 경우 높은 안전성이 요구되는 상황에서는 추가적인 PIN 입력을 통해 입력 편리성을 보장하면서 사용자 인증을 수행하여 안전한 금융거래가 가능하다.

  • The study aims to investigate factors affecting enterprise's satisfaction and loyalty toward the Social Security's online public services, looking at the case of Thanh Hoa province, Vietnam. This study employs samples with 216 enterprises that use online public system of Thanh Hoa province's Social Security. The research model is closely linked to the SERVQUAL model developed by Parasuraman, Zeithaml and Berry (1988). We propose 23 scales that constitute the quality of service, three scales that constitute Customer Satisfaction and three components that constitute Customer Loyalty. This study use the tool of Exploratory Factor Analysis (EFA), Cronbach's Alpha test, Confirm Factor Analysis (CFA) and Structural Equation Modeling (SEM) in order to address the question of satisfaction and loyalty. The result shows that the factor with the most impact is Reliability, next is Capacity of staffs, Tangibles, Attitude of staffs, and the least impacting factor is Empathy; moreover, the results also show that Satisfaction has a strong impact on Customer Loyalty. The findings of this study suggest that Thanh Hoa province's Social Security should: (i) strengthen the reliability of online service system; (ii) build capacity for staffs; (iii) develop the responsiveness of electronic transactions systems; and (iv) improve the empathy of staffs.
