An Architecture for Differentiated Security Service

Applications on network need not only enough quality of service (QoS) but also enough quality of security service (QoSS) because the security is essential for most of applications on network. The purpose of QoSS is to organize various security services together to achieve enough security for applications. As security requirements vary dramatically for different applications, differentiated security services (DSS) are necessary to realize the QoSS. This paper provides an architecture of DSS that is not only general enough to various types of scenarios, such as mobile communication and Internet communication, etc, but also compatible enough to current network solutions and technologies.
