Additional User Authentication on Group Communication
Noe Lopez-Benitez,Sunghyuck Hong 중소기업융합학회 2015 중소기업융합학회 국제학술대회논문집 Vol.2 No.1
Group communications are becoming popular in Internet applications such as videoconferences, on-line chatting programs, games, and gambling. However, the conventional group key agreement protocols are focused on minimizing the computational overhead by concentrating on generating the common group key efficiently. As a result, the common group key is generated efficiently but a failure in authentication allows adversaries to obtain valuable information during the group communication. This paper proposes a Media Access Control (MAC)-based authentication in the group key agreement in order to secure the user authentication process in group communications. Without a preliminary agreement, participants in a group communication cannot trust each other in the beginning of the group setup. Therefore, the group controller, who is randomly selected from the group members, needs a security deposit from all members in case an illegitimate user tries to join the group. The user MAC address proposed in this paper can act as a security deposit to provide a secure communication channel while preventing the MAC spoofing problem.

The Software Architecture of A Secure and Efficient Group Key Agreement Protocol
Lopez-Benitez, Noe Convergence Society for SMB 2014 융합정보논문지 Vol.4 No.3
Group communications are becoming popular in Internet applications such as video conferences, on-line chatting programs, games, and gambling. Secure and efficient group communication is needed for message integration, confidentiality, and system usability. However, the conventional group key agreement protocols are too much focused on minimizing the computational overhead by concentrating on generating the common group key efficiently for secure communication. As a result, the common group key is generated efficiently but a failure in authentication allows adversaries to obtain valuable information during the group communication. After achieving the secure group communication, the secure group communication should generate the group key efficiently and distribute it to group members securely, so the balance of security and system usage must be considered at the same time. Therefore, this research proposes the software architecture model of a secure and efficient group communication that will be imbedded into networking applications.

Trends and Implications of Mobile and Online FinTech
Sunghyuck Hong,Sanghee Park,Noe Lopez-Benitez ASCONS 2017 INTERNATIONAL JOURNAL OF EMERGING MULTIDISCIPLINAR Vol.1 No.1
With the advent of the FinTech era, which is an IT technology-based financial service, the service has been transformed into a service emphasizing user-friendly convenience, and new and innovative services are always pouring out. However, due to the nature of FinTech, personal information, financial information, and physical information can be easily exposed, so countermeasures against security threats are essential. Even if we provide innovative services, if we can not provide reliable service and do not get customer’s trust, we will not only lose customers but also result in the decline of brand value. Therefore, this paper examines the security threats of the FinTech market, domestic and overseas industries, and proposes countermeasures to protect consumers from increasingly intelligent and organized security.
