Abstract

Signcryption, introduced by Zheng in 1997, is a public key primitive which has the ingredients of both digital signature and data encryption. In 2001, Chung and Song proposed a collection of signcryption schemes which are generalized from Zheng's seminal schemes. In this paper, we describe a new attack called Known Session Key Attack. We show that the entire collection of Chung-Song signcryption schemes is vulnerable to this attack, while we also show that the original Zheng's schemes remain secure against this new attack. In addition, we comment that Zheng's schemes are not 'Insider Secure' as defined by An, et al. in 2002.
