With the growing deployment of the Internet
infrastructure for diversified multimedia services,
the demand of customized security service for
CMNs is one of the emerging paradigms. In
detail, current Internet is constructed based
on TCP/IP protocol suite while the IP was
not planned with security in mind [6]. These
negative developments threaten to undermine the
potential highly beneficial opportunities of upper
applications [7]. The incredibility of substrate
network will lead to the insecurity of all CMNs
carried by it. For example, the hijacking by
dominating substrate nodes will lead to the rapid
information leakage or baleful propagation in
upper CMNs. So the security of CMNs still relies
on the substrate network-inbounded structure at
the most first, and a security matching between
the substrate fixed structure and upper diversified
CMNs is required.
