29. Leakage-Resilient RFID Authentication with Forward-Privacy.

Author

Matsuo, Shin΄ichiro, Phong, Le Trieu, Ohkubo, Miyako, and Yung, Moti

Abstract

Low power devices, such as smart-card and RFID-tags, will be used around our life including in commercial and financial activities. A prime application of such devices is entity authentication in pervasive environment. The obvious concerns in this environment involves getting security against tag-forgery (even by adversary controlled readers) and, on the other hand, giving users privacy against linking of different authentication transcripts. Many cryptographic protocols have realizes such requirements. However, there is no scheme which realizes, both, forward-privacy and tag-forgery right after some leakage is occurred. Since some devices among the huge quantity of expected devices will surely be compromised, it seems highly important, from an engineering point of view, to deal with limited damage of such exposures. In this paper, we address the gap by proposing the first RFID scheme that realizes both requirements. [ABSTRACT FROM AUTHOR]

30. A Framework for Constructing Convertible Undeniable Signatures.

Author

Kikuchi, Ryo, Phong, Le Trieu, and Ogata, Wakaha

Abstract

In this paper, we propose a framework for constructing convertible undeniable signatures from weakly-secure standard signatures. We then present a concrete instantiation employing a standard signature scheme recently proposed at Eurocrypt ΄09. The instantiation is the first (convertible) undeniable signature scheme whose unforgeability relies on the well-known RSA assumption. [ABSTRACT FROM AUTHOR]

31. New RSA-Based (Selectively) Convertible Undeniable Signature Schemes.

Author

Phong, Le Trieu, Kurosawa, Kaoru, and Ogata, Wakaha

Abstract

In this paper, we design and analyze some new and practical (selectively) convertible undeniable signature (SCUS) schemes in both random oracle and standard model, which enjoy several merits over existing schemes in the literature. In particular, we design the first practical RSA-based SCUS schemes secure in the standard model. On the path, we also introduce two moduli RSA assumptions, including the strong twin RSA assumption, which is the RSA symmetry of the strong twin Diffie-Hellman assumption (Eurocrypt ΄08).
