摘要：

In this paper, we analyse the signcryption scheme proposed by Libert and Quisquater in 2004 and show that their scheme does not meet the requirements as claimed in their paper in PKC'2004, such as, semantically secure against adaptive chosen ciphtertext attack, ciphertext anonymity and key invisibility.
