Abstract: Compared with the traditional network, active network node in the middle of its
programmable features of the new network for the development and expansion of services
provided broad space for development, but there are still many problems restricted the
development of the Active Network. Among them, is an important aspect of security. This article describes ideological and active network technology and characteristics of the architecture and algorithms CCAAN. DSAN elaborated on the active node security design and implementation of the model.
