%X Active network is a new network that promises to provide powerful and flexible network services. All these services are custom-built by active packets sent by network users. However, active networks is more vulnerable before attacks. To solve this problem, resources in active nodes are graded and all accesses to them are controlled by role which is specified by attribute certificate in active packets. Seraphim architecture guarantees security for codes as they are executed. Finally, the realization of role-based dynamic access control is exampled by firewall.
