Abstract

In 2007, Kwon et al. proposed a three-round protocol, SKE, for smart card-based key exchange in the three-party setting which provides both key independence and forward secrecy. This paper demonstrates the vulnerability of the SKE protocol and then presents an improvement to repair the security flaws of the SKE protocol.
