In this article, we show that the scheme is not secure. In particular, if a valid message-signature pair has been revealed, an adversary can forge the signer's ...

Bibliographic details on An Attack on Libert et al.' s ID-based Undeniable Signature Scheme.
In this paper, we give a first example of identity based undeniable signature using pairings over elliptic curves.
An Attack on Libert et al.' s ID-based Undeniable Signature Scheme · Zichen LiC. Chong +5 authors. K. Pun. Computer Science. Int. J. Netw. Secur. 2007. TLDR.
We say that an identity based undeniable signature scheme is existentially un- forgeable under chosen-message attacks if no probabilistic polynomial time (PPT) ...
Libert and Quisquater proposed the first identity-based undeniable signature scheme. In 2007, Li et al. proposed a universal forgery attack on their scheme.
