Network-level security systems rely significantly on network operations. This reliance has led to conventional network-level security systems based on a host-centric architecture because the network operations themselves are based on hosts. However, host-dependent network security schemes are no longer applicable in content-based networks. In this paper, a host-oblivious network security paradigm for content-based networks is introduced, and then a comprehensive security procedure focusing on generating and sharing diverse secret keys is proposed. Then the proposed scheme, which provides not only essential security functions but also diverse security levels, is discussed. Finally, how this multiple security-level approach helps reducing inevitable performance overhead caused by implementing security functions is demonstrated.
