Security on Dynamic ID-based Authentication Schemes
Jingxuan Zhai,Tianjie Cao,Xiuqing Chen,Shi Huang 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.1
Dynamic ID-based authentication schemes based on password and smart card are widely used to provide two-factor authentication and user anonymity. However, these schemes have one or the other possible security weaknesses. In this paper, we analyze the schemes of Li et al. and Wang et al. published in recent years. After the analysis, we demonstrates that Li et al.’s schemes are vulnerable to off-line password guessing attack if the user’s identity is compromised, Li et al.’s scheme cannot withstand the impersonation attack and linkability attack, Wang et al.’s schemes cannot resist off-line password guessing attack if the attacker steals a smart card, Wang et al.’s schemes fail to provide forward security. Our result shows that none of the existing dynamic ID based authentication schemes can achieve all the desirable security goals.

Untraceable Analysis of Lightweight RFID Ownership Transfer Protocol
Xiuqing Chen,Tianjie Cao,Jingxuan Zhai,Yu Guo 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.8
Nowaday, the worldwide applications of RFID technologies have contributed to the development of supply chain system. However, to be confronted with various security and privacy issues in lightweight RFID protocols, the security analysis of lightweight ownership transfer (OT) protocols has become an important task. First and foremost, the passive attacker can further break down the security and privacy of three new published lightweight RFID protocols. Subsequently, the proposed protocol is designed to prevent the traceability attacks. Then, it is significant for us to show how to prove strong forward untraceable and backward untraceable of the improved scheme in security model.

Cryptanalysis and Improvement of RFID Ownership Transfer Protocol
Xiuqing Chen,Qiang Zhao,Tianjie Cao,Jingxuan Zhai 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.12
The widespread use of Radio Frequency Identification (RFID) technologies help to trace a large number of commodity and share the tag information in the supply chain system. However, many ownership transfer protocols are subject to various attacks. We analyze the security of two protocols. Even if the designers claim that their protocols are security, we find that their schemes suffer from forward traceability attacks and tracing attacks. In addition, we show that a weak attacker can retrieve the secrets of the tag with a probability 1 in Kardaş et al.’s protocol. To resist against these attacks, we present an improved scheme based on Kardaş et al.’s protocol by adopting the new key-update mechanism. In the end, we show the enhanced versions provides the forward and backward untraceable security properties.
