Abstract

Recently, Chang and Chan proposed a new key exchange scheme based on the hyperspherical equation. However, we find that the Chang-Chan multiparty key exchange scheme is vulnerable to the malicious participant attack and the modification attack. This paper will show the security flaws in the Chang-Chan scheme.
